The specific embodiment
The present invention relates to be used to control the apparatus and method of the exploitation of hydrocarbon recovery well.The present invention allows multi-form embodiment.Show in view and be that the specific embodiment of the present invention is interpreted as in this detailed description: the present invention is considered to the example of the principle of the invention, rather than the present invention is limited to content in this demonstration and description.Further, though embodiment is described as having one or more features or two or more combination of features, such feature or feature combination should not regard basic as, unless spell out in addition.
At first referring to Fig. 1, shown exemplary well 10, it drills stratum 12 and enters a pair of stratum 14,16, from this to being expected to exploration of hydrocarbons the stratum 14,16.The metal sleeve of in well 10, packing into, this is well known in the art, and several perforation 18 penetrate and extend in the stratum 14,16, and the fluid of exploiting out like this can be from the stratum 14,16 flows into the wells 10.Well 10 has a deflection or substantially horizontal branch 19.Well 10 has back level exploitation assembly, and whole with Reference numeral 20 marks, it is arranged on the well by well tubing or the tubing string 22 that the well head from the face of land 26 of well 10 24 extends downwards.Exploitation assembly 20 limits an inner shaft to flow orifice 28 along its length.One annular space 30 is limited between exploitation assembly 20 and the well bore casing.Exploitation assembly 20 has deflection, a substantially horizontal part 32, and described horizontal component 32 extends along the deflection branch 19 of well 10.Quarrying apparatus 34 is positioned at along on the Chosen Point of exploitation assembly 20.Alternatively, each quarrying apparatus 34 is isolated by a pair of packer device 36 in well 10.Though in Fig. 1, only shown two quarrying apparatus 34,, in fact, can a large amount of such quarrying apparatus of arranged in series along horizontal component 32.
Each quarrying apparatus 34 is characteristics with exploitation control device 38, and described exploitation control device 38 is used for arranging one or more aspects of one or more fluids that flow into quarrying apparatus 20.The mixture, water, salt solution, engineering fluid such as the drilling mud, gentle such as oil that comprise liquid, gas, hydro carbons, heterogeneous fluid, two or more fluids at this employed term " fluid " from fluid such as the water and the naturally occurring fluid of face of land injection.In addition, relate to water, it should be interpreted as also comprising water-based fluid; For example salt solution or salt water.According to embodiments of the invention, exploitation control device 38 can have several and guarantee to operate selectively and control the mobile replacement structure of passing through thus of fluid.
Fig. 2 has shown exemplary open hole well configuration 11, wherein can use quarrying apparatus of the present invention.The structure of open hole well 11 and operate in most of aspects and be similar to aforesaid well 10.But well configuration 11 has not cased boring, and stratum 14,16 is directly led in this boring.So the fluid of exploiting out directly flow into the annular space 30 that is limited between the wall of exploiting assembly 21 and well 11 from stratum 14,16.Not perforation, open hole packer 36 can be used to keep apart collection/control apparatus 38.The characteristics design of exploitation control device becomes the guiding fluid directly 16 to flow into nearest quarrying apparatus 34 from the stratum, forms balanced flow thus.In some cases, packer can dispense from barefoot completion.
With reference now to Fig. 3,, shown to be used to control fluid flows into the exploitation control device 100 in the mining tubular column from reservoir a embodiment.This FLOW CONTROL can become with the one or more features or the parameter (comprising moisture content, fluid velocity, gas content or the like) of formation fluid.In addition, control device 100 can be along one section distribution of recovery well, so that fluid control to be provided in a plurality of positions.This can help, for example, and the exploitation flow of balanced oil under the flow of " heel " of horizontal well may occur greater than the situation of " toe " of horizontal well.By appropriate structuring exploitation control device 100, for example by pressure equalizing or the inflow by restriction gas or water, the well owner can increase the possibility of the efficient discharging of oil reservoirs.Hereinafter discussed exemplary exploitation control device.
In one embodiment, exploitation control device 100 comprises that the particle control device 110 that is used for reducing amounts of particles that fluid carries secretly and size, control are from the inflow control device 120 of the total emissions speed on stratum with based on the flow control apparatus 130 of the composition control inflow region of streaming flow.Particle control device 110 can comprise known devices, and for example sand sieve and the rubble bag that links, inflow control device 120 can utilize and adopt the device that is designed to by the tortuous fluid path of the pressure drop control inflow velocity set up.
Exemplary flow control apparatus 130 can be configured to the fluid of one or more features (for example water content) control inflow metering orifice 102 based on incoming fluid.In an embodiment, flow control apparatus 130 is activated by activeleg 132, and described activeleg 132 reacts with near the prescribed fluid the flow control apparatus 130.By reaction or effect, it means that when being exposed to prescribed fluid activeleg 132 stands the variation of one or more features or aspect of performance.Described feature or performance include but not limited to mechanical performance, electric property and material composition.In addition, in some configuration, variation can be reversible.That is to say that in case prescribed fluid disappears or no longer exists, activeleg 132 can be replied original state.And when being exposed to another kind of prescribed fluid, activeleg 132 also can be replied original state.Illustrative activeleg is described below.
With reference now to Fig. 4 and Fig. 5,, shown the embodiment of a plurality of flow control apparatus 200 and 240, these flow control apparatus 200 and 240 use activeleg 202 and 242 to activate respectively.In an illustrative configuration, activeleg 202 and 242 is combined with shape-memory polymer (SMP) material.The SMP material can be configured to, and when activation parameter surpassed a threshold value, the SMP material stood a transformation, and it shows as the variation of material property aspect.Illustrative activation parameter comprises chemical property and heat.In a configuration, water activates SMP and can use glass transition temperature or Tg as the threshold value based on the activation parameter of heat.Affected material property can be a storage modulus.In an exemplary structure, make water activate the SMP material and be exposed to water, can cause the transformation of SMP, it shows as the variation of storage modulus aspect.Thereby for example, before being exposed to water, the SMP material can have a Tg, is exposed to after the water, can have the 2nd lower Tg.If between a Tg and the 2nd Tg, making water activation SMP material be exposed to water, environment temperature then can cause than hard state and than the conversion between the flexible state.
With reference now to Fig. 4,, flow control apparatus 200 has used activeleg 202, and described activeleg 202 can operationally be coupled in a restricting element 204, and described restricting element 204 is configured to partially or even wholly flowing of restricted passage throttle orifice 206.When throttle orifice 206 was opened, it can provide fluid to be communicated with mobile boring between 102 (Fig. 3) on the stratum.Activeleg 202 by Tg greater than flow control apparatus 200 when activeleg 202 is not exposed to water run into around the water of downhole temperature activate the SMP material and form.For the sake of clarity, activeleg 202 state that is not exposed to the fluid of inducing transformation is called as " zero " and activates.When being exposed to water, the Tg that water activates the SMP material is lower than the downhole temperature on every side that flow control apparatus 200 runs into.In a configuration, lever 208 has a fulcrum at tie point 210 places, and described lever 208 is connected in restricting element 204 with activeleg 202.Activeleg 202 can form the belt of an end of engagement, levers 208, and described lever 208 produces a power, is used to offset the power that promotes restricting element 204 and throttle orifice 206 sealed engagement.In this case, this power is gravity, but in other cases, biased element, hydraulic coupling or the like can promote restricting element 204 towards throttle orifice 206.
At " zero " between active period, activeleg 202 be dimensioned to directed described lever 208, make restricting element 204 not engage or not be seated on the throttle orifice 206 with throttle orifice 206.Harder when " zero " activates because activeleg 202 exists, so lever 208 and restricting element 204 are normally static, and remain on this position.One balance weight protuberance 212 can also be set on lever 208, keep restricting element 204 not landings to help activeleg 202 on lever 208, to apply necessary power.In the time of around the water of q.s is in activeleg 202, activeleg 202 stands a transformation, and it causes the reduction of Tg value.Because new Tg is lower than downhole temperature on every side,, lose the ability that on lever 208, applies reaction force so activeleg 202 becomes gentle.When the weight of restricting element 204 overcame the power that activeleg 202 applies, restricting element 204 rotated and forms landings with throttle orifice 206 and engage.Thereby flow control apparatus 200 is activated by the reaction of activeleg 202 when being exposed to water.This reaction can show as the variation of material property in one aspect, can cash the variation into shape in yet another aspect, perhaps shows as the variation of Tg in yet another aspect.
If around activeleg 202, no longer include water, the value that the Tg value returns to " zero " activates.Thereby activeleg 202 is replied it in " zero " shape between active period and/or size, and this makes restricting element 202 rotate and the engaging of disengaging and throttle orifice 206.Thereby it is reversible that the reaction of activeleg 204 can be considered to.
In some embodiments, the flow control apparatus 200 of Fig. 4 can be oriented in well, makes gravity can pull down dynamic throttling element 204 and engages with throttle orifice 206.In other embodiments, flow control apparatus 200 can be rotatably installed on the well tubing 22 (Fig. 1), and it comprises the balance weight (not shown).Thereby when being arranged in well, balance weight makes restricting element 204 rotate to the high side position of well, thereby allows gravity to act on restricting element 204 with aforementioned manner.
With reference now to Fig. 5,, flow control apparatus 240 has used activeleg 242 in a circuit 244, and described circuit 244 can move or displacement node fluid element 246, and described restricting element 246 is flowing of restricted passage throttle orifice 248 partially or even wholly.When throttle orifice 248 was opened, it can provide the stratum to be communicated with the fluid that flows between boring 102 (Fig. 3).Activeleg 242 activates the SMP material by water and forms, and its make is with described identical with respect to Fig. 4.In a configuration, restricting element 246 is coupling in a pivoting member 250 places in the mode that allows to rotate between open position and fastening position.Restricting element 246 can be formed by the nonmetals that comprise magnetic element 252, described magnetic element 252 and circuit 244 actings in conjunction.In illustrative structure, circuit 248 produces a magnetic field suction magnetic element 252.The power pulling that applies by the magnetic field that produces or rotate restricting element 246 and be disengaged with throttle orifice 248.Circuit 244 can utilize and use the ground apparent source and/or the down-hole power of suitable conductor supply power to pass to electric current.Exemplary down-hole power comprises generator and battery.
If water no longer centers on activeleg 242, the value that the Tg value returns to " zero " activates.Thereby activeleg 242 is replied it in " zero " shape between active period and/or size, and this has compressed spring 262, and makes magnetic trigger 260 get back to primary importance.Because magnetic element 260 no longer influences switch 254, switch 254 is switched on electromagnetic circuit 256 again, and the magnetic field that is produced is rotated restricting element 244 and is disengaged with throttle orifice 248.Thereby it is reversible that the reaction of activeleg 242 can be considered to once more.
In some embodiments, the flow control apparatus 240 of Fig. 5 can be arranged in well, makes gravity can pull down dynamic throttling element 246 and engages with throttle orifice 248.In other embodiments, flow control apparatus 200 can be rotatably installed on the well tubing 22 (Fig. 1), and it comprises the balance weight (not shown) in aforementioned mode in conjunction with Fig. 4.
With reference now to Fig. 6,, shown a flow control apparatus 280, it has utilized activeleg 282, and described activeleg 282 blocks selectively and passes flowing of throttle orifice 284.Activeleg 282 can activate the SMP material by water and form, and uses as the object that is commonly called " penetrating pin (dart) ", and described " penetrating pin " can the downward pumping from the face of land.Activeleg 282 can have " zero " in downward pump period and activate, and wherein the shape and/or the size permission element 282 that have of activeleg 282 enters throttle orifice 284.Thereafter, be exposed to water, element 282 is expanded, become and be fixed within the throttle orifice 284, thereby partially or even wholly stop up throttle orifice 284.In other embodiments, activeleg 282 can be arranged in the throttle orifice 284 between initial installation period, and can be formed by the SMP material that oil activates.Be exposed to oil or other hydro carbons, can cause that activeleg 282 is transformed into reduced size from a size.Thereby in the time of around oil is in throttle orifice 284, activeleg 282 sizes reduce, and abscission joint discharge orifice 284.In other embodiments, activeleg 282 can be arranged on the throttle orifice 284 or in the throttle orifice 284, with the character according to surrounding fluid, control flowing by throttle orifice 284 selectively.
Should be understood that above-mentioned configuration only is to the explanation according to flow device of the present invention.For example, in some distortion, activeleg can form with fluid has irreversible reaction.For example, activeleg can use the material of prescribed fluid being reacted by decomposing.The exemplary types of decomposing includes but not limited to oxidation, dissolving, melts and breaks.With reference to figure 5, activeleg 242 can be formed by the material such as aluminium, when being exposed to water, and described material oxidation or corrosion.Thereby in case water has sufficiently corroded aluminium base activeleg 242, biased element 262 just will make magnetic trigger 258 be converted to the second place.
