However, for a swash wells or horizontal wells apparatus and method, if appropriate, such terms may refer to a left to right, right to left, or other relationships.

[0021] 在此描述的实施例通常涉及机械采油系统,例如,与油气井相关的机械采油系统。 [0021] Example embodiments described herein relate generally to artificial lift systems, e.g., oil and gas wells and associated artificial lift system. 所述实施例包括用于分离井流体组分,例如油、水和固体的系统和方法。 The embodiment comprises, for example, a system and method for separating a well fluid components oil, water and solids. 例如,一个实施例涉及井下油/水/固体分离以及涉及管控用于操控井流体组分分离的背压。 For example, one embodiment relates to downhole oil / water / solids separation and to control for manipulating the well fluid backpressure fractionation. 一种控制油和水的分离的方式例如通过调节施加给油流和/或水流的背压进行。 Separation of oil and water in a controlled manner and to such oil flow or back pressure / flow by adjusting applied. 背压可通过调节限流控制,以实现对退出井流体组分分离器的油流和/或水流的期望节流。 Back pressure may be controlled by adjusting the flow restrictor to achieve the desired expansion of the well fluid component exits the separator oil flow and / or flow. 除了井流体组分分离以外,在此描述的实施例涉及被设计用于向输出流提供期望节流、即背压的设备。 In addition to the well fluid fractionation, embodiments described herein relate to the desired throttle is designed to provide the output stream, i.e., the back pressure device. 节流幅度可根据井流体的油/水/固体含量在完全关闭(没有流动)到宽开口(充分流动)之间变化。 Throttling the oil well fluid according to the amplitude / water / solids content is fully closed (no flow) to the opening width (full flow) vary.

[0022] 控制背压和相关流动可与注水区相对于生产区(生产区的井上或井下方向的注水区)的方位高度地相关。 [0022] The back pressure control and flow associated with injection zone with respect to the orientation of the production zone (uphole or downhole injection zone of the production zone) is highly relevant. 这两个方位之间的一些差别涉及井上注入(injecting uphole) 和井下注入(injecting downhole),在所述井上注入中,装置可以单一操作节流和通到油管环空,在所述井下注入中,装置可能需要对流动“在线”节流,即,需要从油管接收注入流, 对该流进行节流,然后将该流返回到向着注水区行进的另一油管。 Some differences between these two orientations relates Inoue injection (injecting uphole) and the downhole injection (injecting downhole), the uphole injection, the throttling means may be a single operation through the tubing and annulus in the downhole injection , flow devices may require "online" throttling, i.e., needs to receive from the injection pipe flow, the flow is throttled and the flow returns to the other tubing traveling towards the injection zone. 在一些应用中,限流器的节流通道/或开口的直径可在大约0. 125英寸到1. 0英寸的范围内。 In some applications, the throttling passage / or diameter of the opening of the flow restrictor may be in the range of about 0.125 inches to 1.0 inches of.

[0023] 总体上请参看图1,井系统20被示为部署在井眼22中。 [0023] Referring generally to Figure 1, a well system 20 is shown deployed in the wellbore 22. 在该实施例中,井系统20包括潜入式电力泵送系统对,所述潜入式电力泵送系统M具有潜入式马达26和由潜入式马达沈驱动的潜入式泵28。 In this embodiment, well system 20 comprises a submersible pumping system power, the power submersible pumping system having a submersible motor M by a submersible motor 26 and sink 28 is driven submersible pump. 潜入式电力泵送系统M可包括多种其他构件、例如泵开口或进入口30和马达保护器32。 M Power submersible pumping system may include various other components, such as a pump or inlet port opening 30 and a motor protector 32. 附加性地,示出的井系统20还包括被设计成用于分离井流体组分的分离器34,例如离心分离器或旋流分离器。 Additionally, the well system 20 shown also includes a separator designed for separating a well fluid components 34, such as a centrifugal separator or a cyclone separator. 例如,分离器34可被设计成用于分离流体组分、例如油和水,流体和固体组分、例如水和颗粒,或其他组分组合、例如油、水和固体。 For example, separator 34 can be designed to separate fluid components, such as oil and, fluid and solid components, such as water and granules, other components, or a combination of water, such as oil, water and solids. 分离器34可在多种位置、例如在示出的潜入式泵观上方的位置连接到井系统20中。 Separator 34 may be at a variety of locations, such as the well system 20 is connected to a position above the submersible pump concept illustrated. 然而, 分离器34还可定位在潜入式泵观的上游,以限制固体流过泵观。 However, the separator 34 may also be positioned upstream of the submersible pump concept, to restrict solids flow through the pump concept.

[0024] 在示出的示例中,井系统20放置在油气井的井下,例如井的套管36内。 [0024] In the example shown, the well system 20 is placed downhole in oil and gas wells, for example, in the well casing 36. 当放置在井下期望位置处时,潜入式马达26可供给动力,以驱动潜入式泵观和分离器34。 When placed at a desired downhole position, submersible motor 26 may be powered to drive the submersible pump 34 and the separator concept. 在该实施例的操作过程中,井流体通过开口30被吸入泵观中且被泵送到分离器34中。 During operation of this embodiment, well fluid sucked into the pump through the opening 30 and is pumped to the concept of the separator 34. 分离器34加速并沿圆形路径驱动井流体混合物,从而,利用离心力将密度较大的物质、例如水和固体定位到更远的径向位置,以及将密度较小的流体、例如油定位到与转动中心更接近的位置。 Separator 34 to accelerate the fluid mixture and drives the well along a circular path, so that, by centrifugal force denser substances, such as water and solid positioning farther radial position, and the less dense fluid, such as oil targeting and a position closer to the center of rotation. 在该示例中,油流和水流从分离器34排出并沿着不同的路径单独地行进到方向改变装置38, 所述方向改变装置改变水流的方向,并将水流注入周围地层中,同时例如通过油管40将油流向井上引导到地面收集位置。 In this example, the oil and water streams 34 and discharged separately to travel along different path direction changing means 38, the direction changing means to change the direction of water flow, and the flow of water injected into the surrounding formation from the separator, at the same time by e.g. the pipe 40 guiding the oil to flow uphole to the surface collection location. 分离器34可被设计成用于分离油、水和固体(参看图10), 在这种情况下,井流体的固体组分被方向改变装置38引导到期望位置。 Separator 34 may be designed for separation of oil, water and solids (see FIG. 10), in this case, the solid component of the well fluid in the direction of the device 38 is changed to a desired location. 应当指出,分离器34也可在具有或没有方向改变装置38的情况下用于多种位置。 It should be noted that, in the separator 34 may be used with or without a plurality of direction changing means 38 the position of the case. 例如,分离器34可用于分离油、水和固体组分,然后再将固体与油流组合以给送到期望的地面收集位置,从而,避免堵塞注水区。 For example, separator 34 can be used to separate oil, water and solid components, then the solid composition to the oil stream fed to the desired position of the collection surface, thus avoiding clogging of injection zone.

[0025] 关于水流、油流和/或固体流,从分离器34的输出是指分别大致具有水、油和固体的浓度的流。 [0025] For water, oil flow and / or solids flows, the output 34 from the separator means each having a substantially water flow, the concentration of oil and solids. 换言之,相应的流可包含一部分其他井流体组分,不可能是纯的而仅包含水、 油或固体。 In other words, the stream may comprise a portion of the respective other component of the well fluid, it is impossible and only containing pure water, an oil or a solid. 根据特定的应用场合,井系统20可包括其他各种构件,例如封隔器42和44。 Depending on the particular application, the well system 20 may include various other components, such as the packer 42, and 44.

[0026] 图2示出了分离器34的一个示例的剖视图,在这种情况下,所述分离器是离心式分离器。 [0026] FIG. 2 shows a sectional view of an example of the separator 34, in this case, the separator is a centrifugal separator. 井流体混合物被驱动通过分离器34的井流体入口45并进入分离器部分或分离器34的腔室46、例如旋流腔室中。 Well fluid mixture is driven through the well fluid separator 34 and the inlet 45 into the separator or separator portion of the chamber 4634, such as the cyclone chamber. 井流体的组分通过分流器48分离,所述分流器48限定出用于从分离器部分46运送已被分离的井流体组分的管道或通道。 Separation of components of the well fluid through the shunt 48, the flow diverter 48 defines a passage for the pipe or has been separated from the conveying portion 46 of the separator well fluid components. 例如,通道可包括充当分离器腔室46的出口的油通道或管道50和水通道或管道52。 For example, the channel may include a passage or pipe serving as an oil separator chamber 50 and outlet 46 of the conduit 52 or the water passage. 分流器48还可从井流体分离出另外的组分,例如固体,所述固体沿着单独的固体通道或管道传送。 Splitter 48 is separated from the well fluid may be an additional component, such as a solid, the solid along a separate channel or conduit conveying solid. 如图所示,油通道50 相对于水通道52在径向方向上偏内设置。 As shown, the oil passage 50 with respect to the water passage 52 is provided within the bias in the radial direction. 背压可选择性地施加给油流、水流和/或固体流, 以影响分离过程。 Back pressure selectively applied to the flow of oil, water and / or solids flows, in order to influence the separation process. 例如,当分流具有高百分比的油的井流体时,通过水通道52作用于水流的背压可改善分离结果。 For example, when the shunt well fluid having a high percentage of oil by water passage 52 acting on the backpressure flow separation results can be improved. 对于具有较高百分比的水的井流体,通过油通道50作用于油流的较高的背压可类似地改善油和水的分离。 For the well fluid having a higher percentage of water, a higher back pressure acting through the oil passage 50 on the oil flow can similarly improve the separation of oil and water. 总体上,相同的背压原理适用于旋流或离心式分离器。 In general, the same principles apply to the back pressure cyclone or centrifugal separator. [0027] 总体上参看图3,示出了另一类型的分离系统M的剖视图,所述分离系统具有分离器34,该分离器用于将井流体组分分成例如流过油通道50和水通道52的流。 [0027] Referring generally to FIG 3, shows a cross-sectional view of another type of separation system M, a separation system having a separator 34 which separates the well fluid components for example, into the water passage 50 and the oil flowing through the passage stream 52. 应当指出, 分离器34也可设计成分离出固体组分,所述固体组分然后沿着单独的管道输送,这将在下面进行更详细的描述。 It should be noted that the separator 34 may also be designed to separate the solid component, said solid component and, as will be described in more detail in the following along a single pipeline. 在图3中,箭头56示出了表示油流的路径,箭头58示出了表示水流的路径。 In Figure 3, arrow 56 shows the path of the oil flow represented by arrow 58 shows the path represented by the water flow. 在该示例中,限流器60、例如节流构件定位在水通道52中。 In this example, the flow restrictor 60, for example, the throttle member 52 is positioned in the water passage. 然而,替代性地,限流器60也可放置在油通道50中,或另外的限流器60可放置在油通道50中而使得在水通道和油通道中均具有限流器。 However, alternatively, flow restrictor 60 may also be placed in the oil passage 50, or other flow restrictor 60 may be placed in the oil passage 50 so that the water passage and the oil passage has a flow restrictor. 在该实施例中,水流58向井上流入限流器60中。 In this embodiment, the flow restrictor 58 into the flow uphole to 60.

[0028] 限流器60可以从多种不同类型的限流器中选择,其中一个示例具有节流孔件62, 所述节流孔件具有通流节流孔或通道64。 [0028] The flow restrictor 60 may be selected from a variety of different types of flow restrictors, one example of a member orifice 62, the orifice member having an orifice or flow passage 64. 节流孔64的尺寸可以变化,且限流器60和节流孔件62的结构使得能够调节水流58中的背压。 The size of the orifice 64 may be varied, and the flow restrictor member 60 and the orifice 62 of the structure 58 makes it possible to regulate the flow of back pressure. 例如,限流器60可以是可移除的限流器,以便能被更换为具有不同的节流性能的其他限流器60,例如具有尺寸不同的通流节流孔64 的不同的节流孔件62,从而,能够调节背压。 For example, the flow restrictor 60 may be removable flow restrictor, to be replaced with another flow restrictor 60 having a throttle different properties, for example different sizes of the different through-flow orifice 64 of the throttle hole member 62, whereby the back pressure can be adjusted. 在其他实施例中,节流孔件62可移除,且可更换为具有尺寸不同的节流孔64的其他节流孔件62。 In other embodiments, the orifice member 62 may be removed and may be replaced with another orifice having a different orifice size of 64 62. 限流器60和/或节流孔件62可借助于工具66更换,所述工具可下放到井下,以放置和/或移除限流器60或节流孔件62。 Flow restrictor 60 and / or orifice 62 by means of the replacement tool 66, the tool may be lowered into the underground, to place and / or removed or the flow restrictor 60 orifice member 62. 作为示例,用于更换装置的工具可以包括在电缆、钢丝(slick line)、连续油管或其他合适的传送装置68上运行的工具。 As an example, the tool may comprise means for exchanging the tool run on a cable, wire (slick line), coiled tubing, or other suitable transfer means 68. 在一些应用场合下,钢丝可以是用于改变节流特性的最经济的传送装置。 In some applications, the wire may be the most economical means of transmission for changing the throttle characteristic. 在图3中示出的示例中,油管道50可被定位或构造成防止由传送装置68下放的工具意外地进入油通道50中。 In the example shown in FIG. 3, the oil pipe 50 may be positioned or configured to prevent the tool decentralization transfer means 68 in the accidental entry of the oil passage 50. 例如,油通道50可具有倾斜部分70,以防止工具66进入管道中,或管道的尺寸可被选择成使工具66不能进入通道中。 For example, the oil passage 50 may have an inclined portion 70 to prevent the size of the tool 66 into the pipe or conduit may be selected such that tool 66 can not enter the passage.
