Abstract

A flow control system for use together with a subterranean well may include a flow chamber through which a fluid composition flows, and a closure device which is biased toward a closed position in which the closure device prevents flow through the flow chamber. The closure device can be displaced to the closed position in response to an increase in a ratio of undesired fluid to desired fluid in the fluid composition. A structure can prevent the closure device from being displaced to the closed position. The fluid composition can flow through the structure to an outlet of the flow chamber.

[0019] 详细说明 [0019] Detailed Description

[0020] 在图1中代表性地示出了可以体现本披露的原理的一种井系统10。 [0020] In FIG. 1 representatively illustrates the principles of the present disclosure may be embodied in a well system 10. 如图1所描绘的,井筒12具有从套管16向下延伸的大体竖直的无套管区段14以及延伸穿过地层20的大体水平的无套管区段18。 Depicted in FIG. 1, a wellbore 12 having a generally vertical uncased section extending downwardly from the sleeve 16 and the uncased section 14 extending substantially horizontally through the formation 20 18.

[0021] 管柱22 (如生产管柱)被安装在井筒12之中。 [0021] The tubular string 22 (such as a production tubing string) is mounted in the wellbore 12. 在管柱22中,多个井筛24、可变流阻系统25以及封隔器26互相连接。 In the column 22, a plurality of well screens 24, variable flow resistance system 25 and the packer 26 connected to each other.

[0022] 封隔器26密封了径向形成在管柱22与井筒段18之间的环空28。 [0022] The packer 26 sealing the annulus formed radially between the tubular string 22 and the wellbore section 18, 28. 以此方式,流体30可以从地层20的多个层段或区带经由相邻对的封隔器26之间环空28的多个隔离部分而产生。 In this manner, fluid 30 may be produced via an adjacent pair of the plurality of packer annulus 28 between the isolation portion 26 with segments from a plurality of layers or strata 20.

[0023] 定位在每对相邻的封隔器26之间的井筛24和可变流阻系统25在管柱22中互相连接。 [0,023] is positioned at each pair of adjacent packer well screen system 24 and a variable flow resistance between 25 and 26 connected to each other in the column 22. 井筛24对从环空28流动到管柱22中的流体30进行过滤。 The well screen 24 in fluid 3022 flows from the annulus 28 to the filter column. 可变流阻系统25基于流体的某些特征来可变地限制流体30到管柱22中的流动。 Variable flow resistance system 25 to variably restrict the flow of fluid 30 into column 22 based on certain characteristics of the fluid.

[0024] 在这点上,应当注意,井系统10是仅作为能利用本披露的原理的各种各样的井系统的一个实例而在附图中示出并在此进行描述。 [0024] In this regard, it should be noted that the well system 10 is only one example of the principles of the present disclosure can utilize a variety of well system is shown in the drawings and described herein. 应当清楚地理解,本披露的原理绝不限于在附图中描绘或在此描述的井系统10或其部件的任何细节。 It should be clearly understood that the principles of the present disclosure is in no way limited to any detail depicted in the drawings or described herein, or a member of the well system 10.

[0025] 例如,在与本披露的原理保持一致的情况下,井筒12并非必须包括大体竖直的井筒段14或大体水平的井筒段18。 [0025] For example, in the case of keeping with the principles of the present disclosure, the wellbore 12 is not necessarily includes a generally vertical wellbore section 14 or substantially horizontal wellbore section 18. 流体30并非必须仅从地层20产生,因为在其他实例中,流体可以被注射到地层中,流体既可以被注射到地层中也可以从地层产生,等等。 Fluid 30 need not be generated only from the formation 20, as in the other examples, the fluid may be injected into the formation, the fluid may be either injected into the formation may be produced from the formation, and the like.

[0026] 井筛24和可变流阻系统25中的每一个并非必须被定位在每对相邻的封隔器26之间。 [0026] The well screen system 24 and each of the variable flow resistance 25 must not be positioned between each pair of adjacent packers 26. 单个可变流阻系统25并非必须结合单个井筛24来使用。 Single variable flow resistance system 25 is not necessarily bound single well screen 24 is used. 任何数量、安排和/或组合的这些部件都可以使用。 Any number, arrangement and / or a combination of these components may be used.

[0027] 任何可变流阻系统25并非必须与井筛24 —起使用。 [0027] Any variable flow resistance system 25 need not be a sieve with a well 24-- used together. 例如,在注射操作中,所注射的流体可以流动穿过可变流阻系统25,而并不也流动穿过井筛24。 For example, in the injection operation, the injected fluid can flow through the variable flow resistance system 25, but also does not flow through the well screen 24.

[0028] 井筛24、可变流阻系统25、封隔器26或管柱22的任何其他部件并非必须被定位在井筒12的无套管区段14、18之中。 Any other member [0028] 24 well screen, variable flow resistance system 25, the packer string 22 or 26 need not necessarily be positioned in the uncased section 12 of borehole 14, 18. 井筒12的任何区段都可以是带套管的或无套管的,并且在与本披露的原理保持一致的情况下,管柱22的任何部分都可以定位在井筒的无套管区段或带套管区段之中。 Any section of the wellbore 12 may be cased or uncased, and in the case of keeping with the principles of the disclosure, any portion of the tubular string 22 can be positioned in an uncased portion of the wellbore or with among the casing section.

[0029] 因此,应当清楚地理解,本披露描述了如何做出并且使用某些实例,但是本披露的原理并不局限于那些实例的任何细节。 [0029] Therefore, it should be clearly understood that this disclosure describes how to make and use certain instances, but the principles of the present disclosure is not limited to any details of those instances. 相反,可以将那些原理应用到使用从本披露获得的知识的各种其他实例上。 Instead, those principles can be applied to use a variety of knowledge obtained from this disclosure of other examples.

[0030] 本领域的技术人员应当认识到,能够调节流体30从地层20的每个区带到管柱22中的流动将会是有益的,例如,以便防止地层中的水锥进32或气锥进34。 [0030] Those skilled in the art will recognize, 30 can be adjusted to the tubular string fluid flow 22 would be beneficial from each region of the formation 20, e.g., in order to prevent water coning or gas intake 32 coning 34. 井中流动调节的其他用途包括但不限于:平衡多个区带的产出(或注入)、最小化不期望流体的产出或注射、最大化所期望流体的产出或注射,等等。 Other uses include, but are well flow regulator are not limited to: balance the plurality of output zones (or injection), to minimize undesirable output or injection fluid, the fluid to maximize the desired output injection or the like.

[0031] 下文更全面地描述的可变流阻系统25的实例可以通过以下方式提供这些益处:如果流体速度增加到超过选定水平,则增大流阻(例如,以便由此平衡区带间的流动、防止水或气锥进等),和/或如果流体粘度降低到选定水平以下,则增大流阻(例如,以便由此限制诸如水或气体等不期望流体在产油井中的流动)。 [0031] The variable flow resistance system hereinafter more fully described in Example 25 can provide these benefits in the following way: if the fluid velocity increases beyond a selected level, increasing resistance to flow (e.g., to thereby balance the inter-zone flow, to prevent water or gas coning, etc.), and / or if the fluid viscosity is reduced to a selected level less, increasing resistance to flow (e.g., to thereby limit such as water or other undesired fluid gas in an oil producing well flow). [0032] 如在此所使用,术语“粘度”用于指示包括运动粘度、屈服强度、粘塑性、表面张力、可湿润性等流变特性中的任何流变特性。 [0032] As used herein, the term "viscosity" is used to indicate comprising kinematic viscosity, rheological properties of the rheological properties of any yield strength, plastic viscosity, surface tension, wettability, and the like.

[0033] 流体是期望流体还是不期望流体取决于正在进行的产出操作或注射操作的目的。 [0033] The fluid is a desired or undesired fluid fluid output depends on the purpose or operation of an injection operation in progress. 例如,如果期望从井中产出油而不是产出水或气体,那么油是期望流体而水和气体是不期望流体。 For example, if it is desired to produce oil from a well instead of produced water or gas, it is desirable oil and water fluid gas fluid is undesirable. 如果期望从井中产出气体而不是产出水或油,那么气体是期望流体而水和油是不期望流体。 If desired, rather than product gas from a well to produce water or oil, it is desirable to gas oil and water fluid and the fluid is undesirable. 如果期望将蒸汽注射到地层中而不是注射水,那么蒸汽是期望流体而水是不期望流体。 If desired the steam is injected into the injection formation, rather than water, the water vapor is desirable fluid is undesired fluid.

[0034] 应当注意,在井下温度和压力下,烃气体实际上可以完全或部分处于液相。 [0034] It should be noted that, at downhole temperature and pressure, the hydrocarbon gas may actually be wholly or partially in the liquid phase. 因此,应当理解,当在此使用术语“气体”时,超临界相、液相、冷凝物相和/或气相都包括在该术语的范围内。 Accordingly, it should be understood that, when used herein the term "gas", supercritical phase, liquid phase, the condensate phase and / or gas are included within the scope of the term.

[0035] 现在另外参照图2,代表性地示出了一个可变流阻系统25、和一个井筛24的一部分的放大比例的截面图。 [0035] Referring now additionally to FIG. 2 representatively illustrates a variable flow resistance system 25, and a sectional view of the well screen 24 in an enlarged scale a part of. 在这个实例中,流体组合物36 (其可以包含一种或多种流体,如油和水,液态水和蒸汽,油和气体,气体和水,油、水和气体等)流动到井筛24中、由此被过滤、并且随后流动到可变流阻系统25的入口38之中。 In this example, fluid composition 36 (which may comprise one or more fluids, such as oil and water, liquid water and steam, oil and gas, water, and gas, oil, water and gas) flow into the well screen 24 thereby it was filtered, and then flows to the inlet 25 of the variable flow resistance in the system 38.

[0036] 流体组合物可以包含一种或多种不期望流体或期望流体。 [0036] The fluid composition may comprise one or more undesired fluid or desired fluid. 蒸汽和水两者可以组合在流体组合物中。 Both steam and water may be combined in a fluid composition. 作为另一个实例,油、水和/或气体可以组合在流体组合物中。 As another example, oil, water and / or gas may be combined in the fluid composition.

[0037] 基于流体组合物的一个或多个特征(如粘度、速度等)来阻止流体组合物36流动穿过可变流阻系统25。 [0037] based on one or more characteristics of the fluid composition (e.g., viscosity, speed, etc.) to prevent the flow of the fluid composition 36 through the variable flow resistance system 25. 随后,流体组合物36经由出口40从可变流阻系统25排放到管柱22内部。 Subsequently, the fluid composition 40 from the outlet 36 inside the variable flow resistance to the exhaust system 25 via the tubular string 22.

[0038] 在其他实例中,井筛24可以不结合可变流阻系统25使用(例如,在注射操作中),流体组合物36可以在相反方向上流动穿过井系统10的多种元件(例如,在注射操作中),单个可变流阻系统可以结合多个井筛使用,多个可变流阻系统可以与一个或多个井筛一起使用,流体组合物可以接收自或排放到井的、除环空或管柱之外的区域中,流体组合物可以在流动穿过井筛之前流动穿过可变流阻系统,任何其他部件可以在井筛和/或可变流阻系统的上游或下游互相连接,等等。 [0038] In other instances, well screen 24 may not bind a variable flow resistance system 25 using a variety of elements (e.g., in the injection operation), the fluid composition 36 can flow through the well system 10 in the opposite direction ( For example, in the injection operation), a single variable flow resistance system can be used in conjunction with a plurality of well screens, a plurality of variable flow resistance system can be used with one or more well screens, the fluid composition may be received from or discharged into the well the region other than an annulus or tubing string, a fluid composition that can flow through the well screen before flowing through the variable flow resistance system, other components may be any of the well screen and / or a variable flow resistance system of upstream or downstream connected to each other, and the like. 因此,应当认识到,本披露的原理绝不限于图2中描绘并在此描述的实例的细节。 Thus, it should be appreciated that the principles of the present disclosure is not limited to the details depicted in Figure 2 and examples described herein.

[0039] 虽然图2中描绘的井筛24为本领域技术人员称为为绕丝型井筛的类型,但是在其他实例中,可以使用任何其他类型或组合的井筛(如烧结网、扩张网、预填网、丝网等)。 [0039] Although Figure 2 depicts a well screen 24 is referred to those skilled in the type of wire-wrapped screen type well, but in other examples, any other type or combination of the well screen (such as sintered wire mesh, expanded net, pre-filled nets, screen, etc.). 如果期望,还可以使用另外的部件(如护罩、分流管、线路、检测仪表、传感器、流入控制装置 If desired, additional components may also be used (e.g., shrouds, shunt tubes, lines, instrumentation, sensors, inflow control means

[0040] 图2中以简化形式描绘了可变流阻系统25,但是在优选实例中,该系统可以包括用于执行多种功能的多种通道和装置,如在下文更全面地描述。 In [0040] Figure 2 depicts a variable flow resistance system 25 in a simplified form, but in a preferred example, the system may include a variety of channels and means for performing various functions, as described more fully below. 另外,系统25优选至少部分地围绕管柱22周向延伸,和/或该系统可以形成在作为管柱的一部分互连的管状结构的壁之中。 Further, the system 25 preferably at least partially extends circumferentially around the tubular string 22, and / or the system interconnect may be formed in a part of the wall of the tubular string into the tubular structure.

[0041]在其他实例中,系统25可以不围绕管柱周向延伸或不在管状结构的壁中形成。 [0041] In other examples, the system 25 may not extend circumferentially about the column or the wall of the tubular structure is not formed. 例如,系统25可以在平坦结构中形成,等等。 For example, system 25 may be formed in a planar structure, and the like. 系统25可以处于附接到管柱22上的单独外壳中,或者它可以定向成使得出口40的轴线与管柱的轴线平行。 The system 25 may be attached in a separate housing 22 on the tubular string, or it may be oriented such that an axis parallel to the axis of the outlet 40 of the tubular string. 系统25可以位于测井柱上、或附接到形状不是管状的装置上。 Logging system 25 may be located in a column, or attached to the device not tubular in shape. 在与本披露的原理保持一致的情况下,可以使用系统25的任何取向或构型。 In keeping consistent with the principles of the present disclosure, may be used in any orientation or configuration of the system 25. [0042] 现在另外参照图3A和图3B,代表性地示出了系统25的一个实例的更详细的截面图。 [0042] Referring now additionally to FIGS. 3A and 3B, the representatively shows a more detailed cross-sectional view of an example of the system 25. 系统25在图3A和图3B中被描绘为如同从其周向延伸构型中“展开”成大体平面构型。 The system 25 is depicted as extending configuration to "expand" its circumferentially into a generally planar configuration in FIG. 3A and FIG 3B.

[0043] 如上所述,流体组合物36经由入口38进入系统25,并经由出口40离开该系统。 [0043] As described above, the fluid composition 36 into the system 25 via the inlet 38 and leaves the system via outlet 40. 流体组合物36穿过系统25的流阻基于该流体组合物的一个或多个特征而变化。 The fluid composition based on one or more characteristics of the fluid composition 36 varies the flow through the system 25 barrier.

[0044] 在图3A中,相对高速度和/或低粘度的流体组合物36流动穿过从系统入口38到流动腔室46的入口44的流动通道42。 [0044] In FIG 3A, a relatively high speed and / or low viscosity fluid 36 flows through the composition from the system 38 to the inlet flow chamber 46 of the flow channel inlet 44 of 42. 流动通道42在入口44的正好上游具有方向突变48。 A flow passage 42 having an inlet 44 just upstream of the abrupt change in direction 48. 方向突变48被示出为流动通道42中的相对小半径的九十度弯曲,但是如果期望,也可以使用其他类型的方向改变。 48 shows abrupt change in direction is relatively small radius bent ninety degrees in the flow passage 42, but if desired, can also use other types of direction change.

[0045] 如图3A中所描绘,腔室46是大体圆柱形的,并且在方向突变48之前,流动通道42引导流体组合物36相对于该腔室大体切向地流动。 [0045] As depicted in FIG. 3A, the chamber 46 is substantially cylindrical, and 48 before the mutation in the direction of the flow passage 42 to guide the fluid composition 36 with respect to the flow chamber substantially tangentially. 由于流体组合物36的相对高速度和/或低粘度,它不密切遵循该方向突变48、而是替代地经由入口44在相对于从入口44到出口40的笔直方向50实质性地成角度(参见图3A中的角度A)的方向上继续进入腔室46之中。 Since relatively high velocity fluid composition and / or low viscosity of 36, it does not closely follow the abrupt change in direction 48, but instead via the inlet 44 with respect to the straight direction from the inlet 44 to the outlet 40 is substantially 50 angle ( It continues into the chamber 46 in the see angle a in FIG. 3A) direction. 因此,流体组合物36将从入口44迂回地流动到出口40,而最终螺旋向内到达该出口。 Thus, the fluid composition 36 to flow from the inlet 44 to the bypass outlet 40 and eventually reaches the outlet spiral inwardly.

[0046] 相比之下,在图3B中,相对低速度和/或高粘度的流体组合物36流动穿过该流动通道42到达腔室入口44。 [0046] In contrast, in FIG. 3B, a relatively low velocity and / or flow of the fluid composition 36 through which a high viscosity flow passage 42 to the inlet chamber 44. 应当注意,这个实例中的流体组合物36更密切地遵循流动通道42的方向突变48、并且因此在相对于从入口44到出口40的笔直方向50仅略微成角度(参见图3B中的角度α)的方向上流动穿过入口44进入腔室46之中。 It should be noted that, in this example, fluid composition 36 more closely follow the direction of the flow channel 42 mutant 48, and thus α with respect to the inlet 44 to the straight direction of the outlet 40, 50 is only slightly angled (see FIG. 3B angle flows through the inlet 44 into the chamber 46 in) direction. 因此,这个实例中的流体组合物36将直接得多地从入口44流动到出口40。 Thus, in this example, fluid composition 36 to flow much more directly from the inlet 44 to the outlet 40.

[0047] 应当注意,如图3Β中所描绘,流体组合物36也在相对于从入口44到出口40的笔直方向50仅略微成角度的方向上经由出口40离开腔室46。 [0047] It should be noted that, as depicted in Figure 3Β, the fluid composition also with respect to the 36 out of the chamber 46 via the outlet 40 from a direction only slightly angled straight direction 44 to the inlet 50 of the outlet 40. 因此,流体组合物36在基于速度、粘度和/或流体组合物中期望流体与不期望流体的比率而改变的方向上离开腔室46。 Thus, the fluid composition 36 exit the chamber 46 at a desired ratio of the fluid based on the undesired fluid velocity, viscosity and / or fluid composition and changes in direction.

[0048] 应当认识到,与图3Β的实例中的流体组合物采取的直接得多的流动路径相比,图3Α的实例中的流体组合物36采取的迂回得多的流动路径在相同流动速率下耗散该流体组合物的更多能量、并且因此导致更多流阻。 [0048] It should be appreciated that, as compared with the much more direct example of FIG 3Β taken in the flow path of the fluid composition, much circuitous flow paths in the example of FIG 3Α fluid composition 36 taken at the same flow rate the more energy dissipative fluid composition, and thus results in more flow resistance. 如果油是期望流体而水和/或气体是不期望流体,那么应当认识到,当流体组合物中具有的期望流体与不期望流体的比率增加时,图3Α和图3Β的可变流阻系统25将对该流体组合物36提供较少流阻,并且当流体组合物中具有的期望流体与不期望流体的比率降低时,该系统将提供较大流阻。 If oil and water is desired fluid / fluid or gas is not desirable, it should be appreciated that, when increasing fluid composition having a desired ratio of fluid to undesired fluid variable flow resistance system of FIGS 3Α and 3Β 25 provides less resistance to flow of the fluid composition 36 decreases and when the fluid composition having a desired ratio of fluid to undesired fluid, the system will provide greater resistance to flow.

[0049] 由于腔室46具有如图3Α和图3Β的实例所描绘的大体圆柱形的形状,所以从入口44到出口40的笔直方向50是在径向方向上。 [0049] Since the chamber 46 has a generally cylindrical shape and 3Β example of FIG 3Α depicted, so a straight direction from the inlet 44 to the outlet 40 is 50 in the radial direction. 在方向突变48上游的流动通道42是相对于腔室46大体切向定向的(即,垂直于从腔室中心径向延伸的线)。 Mutation 48 in a direction upstream of the flow passage 42 relative to the chamber 46 is substantially tangential orientation (i.e., perpendicular to a line extending radially from the center of the chamber). 然而,在与本披露的原理保持一致的情况下,腔室46不必是圆柱形的,并且从入口44到出口40的笔直方向50并非必须是在径向方向上。 However, in the case of keeping with the principles of the present disclosure, the chamber 46 need not be cylindrical and straight from the inlet 44 to the outlet 40 of the direction 50 is not necessarily in a radial direction.

[0050] 由于这个实例中的腔室46具有带有中心出口40的圆柱形形状,并且流体组合物36 (至少在图3Α中)随着其接近该出口而速度增加、被从入口44到出口的压差驱动而围绕腔室进行螺旋,因此该腔室可以被称为“涡旋”腔室。 [0050] For this example, the chamber 46 has a cylindrical shape with a central outlet 40, and the fluid composition 36 (at least in FIG. 3 [alpha]) as it approaches the outlet and the speed increases, being from the inlet 44 to the outlet the pressure around the driven helical chamber, so that the chamber may be referred to as "swirl" chamber.

[0051] 现在另外参照图4Α和图4Β,代表性地示出了可变流阻系统25的另一个构型。 [0051] Referring now additionally to FIGS. 4Α and 4Β, representatively shows a variable flow resistance system 25 in another configuration. 图4Α和图4Β的构型在许多方面类似于图3Α和图3Β的构型、但是至少在以下方面不同:流动通道42相对于在方向突变48上游的腔室46更多地在径向方向上延伸,并且该方向突变影响该流体组合物36流动远离从入口44到出口40的笔直方向50。 FIG 4Α and 4Β configuration similar to FIG 3Α 3Β configuration and in many ways, but at least in the following points: 42 46 more in a radial direction with respect to the direction of the flow passage 48 upstream of the chamber mutant extending, and which mutations affect the flow direction of the fluid composition 36 from the direction straight away from the inlet 44 to the outlet 40 of 50. [0052] 在图4A中,相对高粘度和/或低速度的流体组合物36受到方向突变48的影响,从而在远离笔直方向50的方向上(例如,以与笔直方向成相对大的角度A)流动到腔室46之中。 [0052] In FIG. 4A, a relatively high viscosity and / or low speed of the fluid composition 36 is affected by abrupt change in direction 48, so that in a direction away from a straight direction 50 (e.g., in a straight direction with a relatively large angle A ) flows into the chamber 46 into. 因此,流体组合物36将在经由出口40离开之前围绕腔室46迂回地流动。 Thus, the fluid composition 36 to flow to the bypass 46 around the chamber before exiting via the outlet 40.

[0053] 应当注意,这与上文针对图3B描述的情形是相反的,在该情形中,相对闻粘度和/或低速度的流体组合物36经由入口44在相对于从入口到出口40的笔直方向50仅略微成角度的方向上进入腔室46。 [0053] It should be noted that for the above described case of FIG. 3B is reversed, in this case, the relative viscosity smell and / or low speed of the fluid composition 36 through the inlet 44 with respect to the outlet from the inlet 40 50 into the chamber 46 only slightly angled in the direction of a straight direction. 然而,图3B和图4A构型的相似性在于,流体组合物36倾向于在流动通道42中随着方向突变48而改变方向。 However, 3B, 4A, and FIG configuration of similarity in that the fluid composition 36 tends to flow in the passage 42 with the abrupt change in direction 48 to change the direction.

[0054] 相比之下,在图4B中,相对高速度和/或低粘度的流体组合物36流动穿过流动通道42到达腔室入口44。 [0054] In contrast, in Figure 4B, the relatively high velocity and / or low viscosity of the fluid composition 36 to flow through the flow passage 42 to the inlet chamber 44. 应当注意,这个实例中的流体组合物36并不密切遵循流动通道42的方向突变48、并且因此在相对于从入口44到出口40的笔直方向50仅略微成角度的方向上流动穿过入口44进入腔室46之中。 It should be noted that, in this example, fluid composition 36 does not closely follow the direction of the flow channel 42 mutant 48, and thus with respect to the direction of flow through the inlet 44 to the outlet 40 of the straight direction 50 is only slightly angled inlet 44 enters into the chamber 46. 因此,这个实例中的流体组合物36将直接得多地从入口44流动到出口40。 Thus, in this example, fluid composition 36 to flow much more directly from the inlet 44 to the outlet 40.

[0055] 应当认识到,与图4B的实例中的流体组合物采取的直接得多的流动路径相比,图4A的实例中的流体组合物36采取的迂回得多的流动路径在相同流动速率下耗散了流体组合物的更多能量、并且因此导致更多流阻。 [0055] It should be appreciated that, compared to much more straightforward to take the example of FIG. 4B fluid composition flow path, the bypass flow path much in the example of FIG. 4A fluid composition 36 taken at the same flow rate dissipate more energy at the fluid composition, and thus causing more resistance to flow. 如果气体或蒸汽是期望流体而水和/或油是不期望流体,那么应当认识到,当流体组合物中具有的期望流体与不期望流体的比率增加时,图4A和图4B的可变流阻系统25将对流体组合物36提供较少流阻,并且当流体组合物中具有的期望流体与不期望流体的比率降低时,该系统将提供较大流阻。 If a gas or vapor is a desired fluid and water / oil or fluid is not desirable, it should be appreciated that, when increasing the fluid composition having a desired ratio of fluid to undesired fluid, variable FIGS. 4A and 4B stream resistance system 25 the fluid composition 36 will provide less flow resistance, and decreases when the fluid composition having a desired ratio of fluid to undesired fluid, the system will provide greater resistance to flow.

[0056] 现在另外参照图5,代表性地示出了将流动控制系统52与可变流阻系统25 —起使用的另一个构型。 [0056] Referring now additionally to FIG. 5 representatively illustrates a flow control system 52 with variable flow resistance system 25 - Another configuration from use. 控制系统52包括可变流阻系统25的某些元件(如流动腔室46、出口40等)、以及关闭装置54和结构56,以便在不可接受水平的不期望流体已经流动穿过系统时防止其流动到管柱22之中。 The control system 52 includes certain elements (e.g., flow chamber 46, outlet 40, etc.) of variable flow resistance system 25, and the closing means 54 and the structure 56, so as to prevent an unacceptable level when the undesired fluid has flowed through the system its flow into the tubular string 22.

[0057] 结构56支撑该关闭装置54远离出口40,直到足够的不期望流体已经流动穿过腔室46而使该结构劣化。 [0057] The support structure 56 of the closure means 54 away from the outlet 40, until enough of the undesired fluid has flowed through the chamber of the deterioration of the structure 46. 在下述另外实例中,结构56抵抗被施加到关闭装置54上的偏置力,其中该偏置力将该关闭装置偏置朝向出口40。 In further examples described below, it is applied to the structure 56 against the biasing force of the closing device 54, wherein the biasing force of the biasing means toward the outlet 40 closed.

[0058] 图5中描绘的关闭装置54具有圆柱形的形状、并且其直径在一定程度上大于出口40,这样使得在该关闭装置被释放时,它将遮挡并防止穿过出口的流动。 [0058] FIG. 5 depicts a closure device 54 having a cylindrical shape, and its diameter to some extent greater than the outlet 40, such that when the closure device is released, it will be blocked and prevented from flowing through the outlet. 然而,在与本披露的范围保持一致的情况下,可以使用其他类型的关闭装置(例如,活瓣等)。 However, in the case where consistent with the scope of the disclosure, other types of closure means (e.g., flaps, etc.).

[0059] 关闭装置54可以设有用于密封地接合围绕出口40的密封表面(例如,座)的密封件或密封表面。 [0059] The closing means 54 may be provided with a sealing surface 40 for sealingly engaging around the outlet (e.g., seats) the seal or sealing surface. 在与本披露的范围保持一致的情况下,可以使用利用关闭装置54来密封的任何方式。 In keeping consistent with the scope of the present disclosure may be used with any embodiment of the closing device 54 for sealing.

[0060] 结构56可以由在与特定的不期望流体接触时相对快地发生腐蚀的材料来制成(例如,该结构可以由在与盐水接触时发生腐蚀的钴制成)。 [0060] The structure 56 may be made of a material relatively quickly corroded upon contact with a particular undesired fluid (e.g., the structure may be made of cobalt corrode when in contact with saline). 结构56可以由在被高速流体冲击时相对快地发生侵蚀的材料制成(例如,该结构可以由铝等制成)。 Structure 56 may be made of a material erosion occurs relatively quickly at high speed is impacted fluid (e.g., the structure may be made of aluminum or the like). 然而,应当理解,在与本披露的原理保持一致的情况下,结构56可以使用任何材料。 However, it should be understood that, while remaining consistent with the principles of the present disclosure, the structure 56 may be any material.

[0061 ] 结构56可以在流体组合物36迂回地流动穿过腔室46时更快地劣化(例如,侵蚀、腐蚀、断裂、溶解、碎裂等等)。 [0061] The structure 56 may be fluid composition 36 through the circuitous flow faster deterioration in the chamber 46 (e.g., corrosion, erosion, rupture, dissolution, fragmentation, etc.). 因此,结构56可以在图3A描绘的相对高速度和/或低粘度的情形下、或在图4A描绘的相对高粘度和/或低速度的情形下更快地劣化。 Thus, the structure 56 may in the case of FIG. 3A depicts a relatively high velocity and / or low viscosity, or deteriorate at a faster 4A depicts a relatively high viscosity and / or low speed situation.

[0062] 然而,应当注意,腔室46并非必须是“涡旋”腔室。 [0062] However, it should be noted that the chamber 46 is not necessarily a "swirl" chamber. 在一些实例中,结构56可以在特定的不期望流体流动穿过腔室46时、在流体组合物36中不期望流体与期望流体的比率增加(无论流体组合物36是否迂回地流动穿过该腔室)等等时释放该关闭装置54以便使其移位到其闭合位置。 In some examples, the structure 56 may in certain undesired fluid flow passes through the chamber 46, the fluid composition 36 in an undesirable increase in the desired ratio of fluid to the fluid (36 regardless of whether the fluid composition to flow through the circuitous chamber) and the like to release the closing means 54 so as to be displaced to its closed position.

[0063] 应当注意,如图5中所描绘,结构56环绕了出口40,并且流体组合物36流动穿过该结构到达该出口。 [0063] It should be noted that, as depicted in Figure 5, the structure 56 surrounding the outlet 40, and the fluid composition to flow through the structure 36 reaches the outlet. 出于这个目的,在大体管状结构56的壁中提供多个开口58。 For this purpose, there is provided a plurality of openings 58 in the wall 56 of generally tubular configuration. 在其他实例中,流体组合物36可以不流动穿过结构56,或者流体组合物可以以其他方式流动穿过该结构(例如,经由结构中的凹槽或槽缝,该结构可以是多孔的,等等)。 In other examples, the fluid composition 36 may not flow through the structure 56, or a fluid composition that can flow through the structure (e.g., a groove structure, via slots or otherwise, which may be porous structure, and many more).

[0064] 现在另外参照图6,在放大比例下代表性地示出了流动控制装置52的另一个实例。 [0064] Referring now additionally to FIG 6, at an enlarged scale representatively illustrates another example of the flow control device 52. 在这个实例中,偏置装置60(如螺旋弹簧、贝氏弹簧垫圈、形状记忆元件等)将关闭装置54偏置朝向其闭合位置。 In this example, the biasing means 60 (e.g., coil springs, Belleville washers, the shape memory element, etc.) biased toward the closing means 54 in its closed position.

[0065] 结构56被插置于关闭装置54与腔室46的壁之间,从而防止该关闭装置移位到其闭合位置。 [0065] Close structure 56 is interposed between the apparatus 54 and the chamber wall 46, thereby preventing the closing device is displaced into its closed position. 然而,当结构56充分劣化(例如,响应于不期望流体与期望流体的比率足够大、响应于足够体积的不期望流体流动穿过系统,等等)时,该结构将不再能够抵抗由该偏置装置施加的偏置力,并且该关闭装置54将被允许移位到其闭合位置,从而防止穿过腔室46的流动。 However, when the structure 56 sufficiently deteriorated (e.g., in response to the undesired fluid is sufficiently large ratio of desired fluid, in response to a sufficient volume of fluid flow through the system is not desirable, etc.), the structure can no longer resisted by the applying a biasing force of the biasing means, and the closure means 54 will be allowed to shift to its closed position, thereby preventing flow through the chamber 46.

[0066] 现在另外参照图7,以透视图代表性地示出了流动控制系统52的另一个实例,其中腔室46的上部壁被移除以供观看该腔室的内部。 [0066] Referring now additionally to FIG. 7 representatively shows a perspective view illustrating another example of the flow control system 52, wherein an upper portion of the chamber wall 46 is removed for viewing the interior of the chamber. 在这个实例中,偏置装置60环绕了关闭装置54的上部部分。 In this example, the biasing device 60 surrounds the upper part of the closing device 54.

[0067] 结构56防止该关闭装置54移位到其闭合位置。 [0067] The structure 56 to prevent the closure device 54 is displaced to its closed position. 偏置装置60在关闭装置54上施加偏置力,从而将该关闭装置偏置朝向闭合位置,但是结构56抵抗该偏置力,直到该结构被充分劣化。 Biasing means 60 is applied to the biasing force of the closing means 54, whereby the closure means biased toward the closed position, but the structure 56 against the biasing force, until the structure is sufficiently degraded.

[0068] 虽然在图3A至图7中描绘的这些实例中,仅使用单个入口44来将流体组合物36引进到腔室46中,但是在其他实例中,如果期望,可以提供多个入口。 [0068] Although in these examples depicted in FIGS. 7 to FIG. 3A, only a single inlet 44 to the fluid composition 36 introduced into the chamber 46, but in other examples, if desired, may be provided a plurality of inlets. 流体组合物36可以同时或分开地经由多个入口44流动到腔室46之中。 The fluid composition 36 may be simultaneously or separately via a plurality of flow inlet 44 to the chamber 46 into. 例如,可以使用不同入口44来用于流体组合物36具有相对应的不同特征(如不同速度、粘度等)的时候。 For example, the inlet 44 may be used for different when the fluid composition 36 having different characteristics corresponding to (e.g., different speeds, viscosity, etc.).

[0069] 虽然上文已经描述了可变流阻系统25和流动控制系统52的多种构型,并且每个构型具有不同于其他构型的某些特征,但应清楚地理解,这些特征并不是相互排斥的。 [0069] While the foregoing has described a variable flow resistance system 25 and flow control system 52 in a variety of configurations, and each having a configuration different from configurations of some other features, it is to be clearly understood that these features They are not mutually exclusive. 相反,上述系统25、52的任何构型的任何特征可以与任何其他构型一起使用。 Conversely, any feature 25.52 said system configuration may be used with any other configuration.

[0070] 现在可以完全认识到,以上披露提供了对控制井中流体流动技术的多个改进。 [0070] it can now fully appreciated that the above disclosure provides improved control of the plurality of the well fluid flow techniques. 流动控制系统52可以在不要求人为干涉的情况下自动操作,以便切断具有相对低粘度、高速度和/或相对低的期望流体与不期望流体比率的流体组合物36的流动。 The flow control system 52 may operate automatically without requiring human intervention, so as to cut off the flow having a relatively low viscosity, high speed and / or relatively low fluid with undesired fluid a desired ratio of the fluid composition 36. 即使系统52在设计上相对简单、构造起来容易并且经济并且在操作上稳健,仍获得了这些优点。 52 even if the system is relatively simple in design, easy to build up and operate a robust economy and still get these benefits.

[0071] 以上披露向本领域提供了一种用于与地下井一起使用的流动控制系统52。 [0071] The above disclosure provides a flow control system for use with a subterranean well 52 to present art. 在一个实例中,系统52可以包括:流体组合物36流动穿过其中的流动腔室46和被偏置朝向闭合位置的关闭装置54,在该闭合位置中,该关闭装置54防止穿过该流动腔室46的流动。 In one example, system 52 may include: flow of the fluid composition 36 through which the flow chamber and closing device 46 is biased toward the closed position 54, the closed position, the closure means 54 to prevent flow through the flow chamber 46. 关闭装置54可以响应于流体组合物36中不期望流体与期望流体比率的增加而移位到闭合位置。 Closing means 54 may be responsive to a fluid composition 36 is not desirable to increase the fluid to a desired fluid ratio is displaced to the closed position.

[0072] 偏置装置60可以将关闭装置54偏置朝向闭合位置。 [0072] The biasing means 60 may be biased toward the closing device 54 closed position.

[0073] 关闭装置54可以响应于不期望流体与期望流体的比率的增加而自动移位。 [0073] The closing means 54 may be responsive to an undesirable increase of the fluid with a desired fluid ratio is automatically shifted. [0074] 不期望流体与期望流体的比率的增加可以造成抵抗该关闭装置54移位的结构56的劣化。 [0074] undesirably increase the rate of fluid with the desired fluid 56 may cause deterioration of the shifting device 54 to resist the closed configuration.

[0075] 流体组合物36可以流动穿过结构56而到达流动腔室46的出口40。 [0075] The fluid composition 36 can flow through the structure 56 to the outlet 40 and flow chamber 46.

[0076] 结构56可以环绕该流动腔室46的出口40。 [0076] The structure 56 may surround the outlet 40 of the flow chamber 46.

[0077] 不期望流体与期望流体的比率的增加可以造成结构56的腐蚀、侵蚀和/或断裂。 [0077] The increase rate of undesired fluid with a desired fluid may cause corrosion, erosion and / or fracture of the structure 56.

[0078] 关闭装置56在释放时可以防止到流动腔室46的出口40的流动。 [0078] The closing device 56 can be prevented when released into the flow chamber 46 of the flow outlet 40.

[0079] 流体组合物36中不期望流体与期望流体的比率的增加可以由流体组合物36中水或气体的增加而导致。 [0,079] The composition of the fluid with undesired fluid 36 desired fluid ratio increases may be caused by an increase in 36 water or gas fluid composition.

[0080] 流体组合物36中不期望流体与期望流体的比率的增加可以由流动腔室46中流体组合物36的速度的增加而导致。 [0080] The fluid composition 36 is not desirable to increase the ratio of the fluid to a desired fluid may be caused by increasing the speed of the fluid flow chamber 46 of composition 36.

[0081] 以上还描述了一种流动控制系统52实例,在该实例中,结构56防止关闭装置54被移位到闭合位置,在该闭合位置中,该关闭装置54防止流体组合物36流动穿过流动腔室46,并且其中流体组合物36流动穿过结构56到达流动腔室46的出口40。 [0081] Also the above described example of a flow control system 52, in this example, structure 56 to prevent the closing means 54 is displaced to the closed position, the closed position, the closure means 54 to prevent the flow of the fluid composition 36 through 46 through the flow chamber, and wherein the fluid composition 36 to flow through the flow structure 56 to the outlet 40 of the chamber 46.
