Even if Fig. 1 shows the flow control apparatus of the present invention in open hole well environment, but technician it will be appreciated that in the art, the present invention is applicable in the well of sleeve pipe equally well.Also have, even if Fig. 1 illustrates a flow control apparatus in each production interval, but technician it will be appreciated that in the art, and any amount of flow control apparatus is configurable in production interval, and can not depart from principle of the present invention.In addition, even if Fig. 1 shows the horizontal component that flow system of the present invention is positioned at pit shaft, but technician it will be appreciated that in the art, the present invention is applicable to have in the well of other directional structure vectorical structure equally well, comprises peupendicular hole, deflection well, inclined shaft, multiple lateral well etc.Therefore, technician it will be appreciated that in the art, such as above, following, upper and lower, upwards, the use of downward, left and right, the directional terminology of upwards creeping into, creeping into downwards etc., to use with respect to the illustrative embodiment shown in figure, upward direction is the top in corresponding diagram, and downward direction is the bottom in corresponding diagram, upwards creeping into (making progress along well bore) direction is towards the ground of well, and creep into (downward along well bore) downwards, is the toe towards well.
Now with reference to Fig. 1-4, the operation of creeping into fluid flow control system downwards that local well state is had to dynamic response is described.In Fig. 1, the tubular type drill string that is illustrated as completion drill string 24 has been positioned at pit shaft 12.A plurality of annular barriers 26 have been configured, and they isolate a plurality of regions; That is, region 1-region N.Regional comprises fluid flow control device FCD1-FCD-N, and it is communicated with one or more other regional fluid ground by flow duct 28-42.Fig. 1 illustrates the first stage of processing operation, wherein, during FCD1 is in an open position, and FCD2-FCDN all in the closed position in, like this, with the processing fluid guiding shown in arrow, flow out outside completion drill string 24, by FCD1 and region 1, flow in stratum 20.Shown in to process operation can be that break operation or other of acid treatment, hydraulic pressure needs the operation of pump, pumping fluid flows in Production Regional or stratum by tubular type drill string downwards.
When processing fluid, by region 1, be pumped into stratum 20 when interior, the pressure P 1 in region 1 will change with local well state variation.For example, in acid treatment process, the pressure P 1 in region 1 is originally under the high pressure higher than reservoir pressure, because the damage of filter block or other pit shaft is flowed the processing fluid in the stratum at inflow wellbore surface place to cause resistance.During filter block in region 1 is removed in acid treatment, pressure P 1 is by with flowing into reducing and reducing of stratum internal resistance.As another example, at some, break in operation, region 1 internal pressure P1 is originally under the high pressure higher than reservoir pressure, because process in a large number that fluid is pumped on the stratum in, formation and support are opened hydraulic pressure and are broken.When breaking, stop propagating, or while there is sand plug, pressure P 1 will increase.Similarly, breaking in operation of other, the pressure P 1 in region 1 is originally under the high pressure higher than reservoir pressure, because process in a large number that fluid is pumped on the stratum in, formation and support are opened hydraulic pressure and broken.For example, when the composition of processing fluid changes to low viscous fluid from high-viscosity gel, pressure P 1 will reduce along with reducing of inflow place intrastratal flow resistance.In the situation of each these processing, pressure P 1 changes in time, and has the pressure sign of expection.
In an illustrated embodiment, because the fluid through annular barrier 26 is communicated with by flow duct 30, by the FCD2 in region 2, see that these pressure in region 1 change.According to the expecting pressure sign of processing in operating process, fluid pressure P1 can send to the appropriate side of FCD2 inner carrier, sliding sleeve or other operating mechanism.The opposite side of FCD2 inner carrier, sliding sleeve or other operating mechanism can be seen the pressure P 2 in region 2, and it is the pressure of initial reservoir.Therefore pressure reduction between P1 and P2 provide the energy to operate FCD2, from the first operative configuration, is converted to the second operative configuration.According to performed operation with by pressure P 1 and P2, send to FCD2, now, the pressure that P1 experience is wished increases or reduces, pressure reduction is formed between P1 and P2, like this, and in an illustrated embodiment, FCD2 is converted to open position from fastening position, as Fig. 2 clearly as shown in.
According to processing the desired output of operation, once FCD2 opens, FCD1 can stay open, or preferably FCD1 can close.In the embodiment shown, because the fluid through annular barrier 26 is communicated with by flow duct 28, by the FCD1 in region 1, see the pressure P 2 in region 2.According to the expecting pressure sign of processing in operating process, fluid pressure P2 can send to the appropriate side of operating mechanism in FCD1, and the opposite side of FCD1 is preferably seen the pressure P 1 in region 1.Therefore pressure reduction between P1 and P2 provides the energy to operate FCD1, from the first operative configuration, is converted to the second operative configuration, in this case, makes FCD1 be transformed into fastening position from open position, as Fig. 2 clearly as shown in.Preferably, before closing FCD1, open FCD2.This up time delay circuit is realized, and regulates the closing velocity of FCD1 such as meter fluid.Once FCD1 closes, it can use spring, chuck or other locked component are mechanically setovered or are locked in fastening position, or it can pass through intrasystem pressure, and all pressure of pipe in this way, is biased to fastening position.
Process the then 2 interior continuation in region of operation, pressure P 2 times to time change, the pressure sign of expection depends on the processing operation of carrying out.Because the fluid through annular barrier 26 is communicated with by flow duct 34, by the FCD3 in region 3, see that the pressure in region 2 changes.According to the expecting pressure sign of processing in operating process, fluid pressure P2 can send to the appropriate side of operating mechanism in FCD3, and opposite side preferably can be seen the pressure P 3 in region 3, and it is the pressure of initial reservoir.Therefore pressure reduction between P2 and P3 provides the energy to operate FCD3, from its fastening position, is converted to open position, as Fig. 3 clearly as shown in.
According to processing the desired output of operation, once FCD3 opens, FCD2 can stay open, or preferably FCD2 can close.In the embodiment shown, because the fluid through annular barrier 26 is communicated with by flow duct 32, by the FCD2 in region 2, see the pressure P 3 in region 3.According to the expecting pressure sign of processing in operating process, fluid pressure P3 can send to the appropriate side of operating mechanism in FCD2, and opposite side is preferably seen the pressure P 2 in region 2.Therefore pressure reduction between P2 and P3 provides the energy to operate FCD2, from its open position, is converted to fastening position, as Fig. 3 clearly as shown in.Preferably, before closing FCD2, open FCD3, and FCD2 is fixed in fastening position.
This process can stepping mode upwards carry out with creeping into, to reach desired processing target, until the final area of pit shaft 12 is processed, as Fig. 4 clearly as shown in, wherein, FCDN opens to allow and processes fluid and enter as shown by arrows region N, and all other flow control apparatus are all closed.After processing has operated, according to the pressure reduction of order in region, change, each flow control apparatus of previously having closed can move to open position.For example, when produced fluid enters into region N, pressure P N drops under reservoir pressure.Because the fluid through annular barrier 26 is communicated with by flow duct 40, by the FCDN-1 in the N-1 of region, see that this pressure in the N of region changes.Fluid pressure PN can send to the appropriate side of operating mechanism in FCDN-1, and opposite side is preferably seen the pressure P N-1 of region N-1.Pressure reduction between PN and PN-1 can be used as the energy and operates FCDN-1, from its fastening position, is converted to open position.This process can stepping mode carry out downwards with creeping into, until All Ranges is opened and is produced.
Now with reference to Fig. 5-6, the another kind operation of creeping into fluid flow control system downwards that local well state is had to dynamic response is described.In Fig. 5, the tubular type drill string that is illustrated as completion drill string 24 has been positioned at pit shaft 12.A plurality of annular barriers 26 have been configured, and they isolate a plurality of regions; That is, region 1-region N.Regional comprises fluid flow control device FCD1-FCD-N, and it is communicated with one or more other regional fluid ground by flow duct 28-42.Fig. 5 illustrates production operation, wherein, during each flow control apparatus is in an open position, makes to be flowed in completion drill string 24 by each flow control apparatus and regional by the production fluid shown in arrow.
In production operation process, the inflow current control parts in FCD1-FCDN will regulate with balance by the productivity ratio of regional.Yet, in some cases, flow into current control parts and may not regulate peace weighing apparatus productivity ratio, or owing to flowing through the variation of a certain region flow, or flow into the variation of producing fluid composition in a certain region, can require the fluid of one or more regional productions to be closed or its production of height restriction.For example, if require the fluid produce in well system, be oil, and one or more region start to produce such as gas or the such undesirable fluid of water, fluid flow control system of the present invention is dynamically in response to this local well state.Because oil viscosity is usually higher than the viscosity of gas or water, when oil moves to pit shaft by stratum, its pressure drop standing is greater than the pressure drop that water or gas stand.Like this, when water or gas generation are in region time, the pressure in this region is greater than the pressure in the region producing oil.Similarly, if the flow that flows into a certain region because dehiscence furrow in stratum increases, in stratum, the region of this lower resistance can cause the production of early water or gas.Like this, when oil is from the regional production of high osmosis in stratum during to a certain region, the pressure in this region is greater than the pressure in the region producing oil by the normal permeability zones in stratum.In each these production situations, can carry out production control with the pressure reduction in various regions.
In an illustrated embodiment, if changing, flow or fluid composition caused region 2 internal pressures higher than region 1 or region 3, or higher than both,, owing to being communicated with by flow duct 30,32 fluids through annular barrier 26, the FCD2 in region 2 can see these pressure reduction.Fluid pressure P1 or P3 can send to the appropriate side of FCD2 inner carrier, sliding sleeve or other operating mechanism, and the opposite side of FCD2 inner carrier, sliding sleeve or other operating mechanism is seen the pressure P 2 in region 2.Therefore pressure reduction between P1 and P2 or P3 and P2 provide the energy to operate FCD2, from the first operative configuration, is converted to the second operative configuration.For example, when pressure reduction reaches predeterminated level, can operate FCD2 from its open position to chokes position, or FCD2 can operate and from its open position to fastening position, as Fig. 6 clearly as shown in.Preferably, then FCD2 is fixed in fastening position.In whole wellbore systems, without intervening this process that continues, because produce flow or the composition of fluid, in various regions, change, pressure reduction provides energy to close the flow control apparatus of requirement.Should be noted that, operating the required pressure reduction of various flow control apparatus can be different in zones of different, and can select in advance or be scheduled to.
Although described the present invention with reference to illustrated embodiment, this description is not intended to be considered to conditional implication.Technician, after describing with reference to this, will be appreciated that various modifications and combination and other embodiments of the invention of illustrated embodiment in the art.Therefore, attached claims are intended to comprise any so modification or embodiment.
