Description
Technical field
The utility model is related to a kind of oil well completion tubing string, more particularly to a kind of intelligent sand control water-control sieve tube.
Background technology
With the development of petroleum exploration and development technology, using horizontal well technology development of fields, raising oil field is had become
Recovery ratio and well yield, exploitation remaining oil, an effective technology means of reduction production cost per tone oil.Horizontal well increase pit shaft with
The contact area of oil reservoir, can preferably develop oil sheet or the larger oil reservoir of vertical permeability, the work in exploitation petroleum resources
With increasingly important.And domestic horizontal well majority has been enter into high water cut rate at present, horizontal well produces yield after water breakthrough and declined rapidly.
Most of horizontal wells in some oil fields are even just gone into operation with regard to water breakthrough soon, make the oil recovery benefit of horizontal well by serious shadow
Ring.Horizontal well is due to the particularity of well track, once water outlet is difficult control.Therefore, each oil field is all in the urgent need to a kind of effective
Controlled level well water outlet, increases crude output, extends the water control technique in horizontal well life-span.
At present, applying the horizontal well water control technique in oil field mainly has three kinds：First, it is segmented variable density screen casing water control technique：
The technology changes the Kong Mi of every section of screen casing of horizontal segment according to the change of Reservoir Permeability, and throttling is adjusted using different holes are close,
Bottom pressure section is adjusted, for Homogeneous Reservoir, reduces, increase difference pressuring loss close with stomidium；Increase toe-end hole close, reduce pressure difference
Loss, to reach balanced production pressure difference, reduces the purpose of bottom water coning speed.2nd, central tube water control technique：The principle of the technology
It is on the basis of screen casing, bushing pipe or perforation completion, one section of minor diameter tubing to be hung under horizontal segment, the fixed length of net horizontal section one is stretched into
Degree, and the annular space between little oil pipe and sleeve pipe is closed with packer, change the liquid flow direction of horizontal well heel end, cut open pressure
Face and pit shaft inflow profile become gentle.3rd, ICD water control techniques：ICD (Inflow Control Device) is a kind of balanced
Flow control apparatus, equilibrium level section is lost along stroke pressure, obtains approaches uniformity inflow profile of the oil reservoir along horizontal well pit shaft.
But, all there are two major defects in these currently used water control techniques：First, can not be according to each section of underground oil
How much layer moisture content carries out automatic and regulation in real time, segmentation variable density screen casing water control technique need to according to the change of Reservoir Permeability,
The screen casing hole for being pre-designed every section in horizontal segment is close；Central tube water control technique must be in advance according to reservoir geology feature design centre
Pipe diameter and the length for stretching into horizontal segment；ICD water control techniques are also the number that ICD water control valves are pre-designed according to reservoir geologic characteristic
Amount.2nd, existing horizontal well water control technique can only quantify the inflow for limiting underground fluid-mixing, and reservoir geology number is being collected in advance
According to deisgn product and tool parameters after progress data analysis are expected to reach that production profile is balanced after going into the well, so as to reduce water
Coning.But in practical application, underground state is not stop change, once enter well using these existing control wetting system tubing strings,
Parameter can not be adjusted or changed, and preferably control water effect is not reached at all.
The steady oil tech of intelligent water-controlled becomes passive type control water by the flow control valve that is self-regulated (AICD) and controlled into the intelligence of active
Water, can automatically adjust the flow that oil-water mixture enters extraction system with the dynamic change of underground oil-water viscosity of mixed liquid；Have
Effect prevents the quick coning of horizontal well bottom water, controls High water cut output, extends low aqueous productive life and oil well service life；Have
The characteristic such as high temperature high voltage resistant, corrosion-resistant.But the flow control valve that is individually self-regulated can only control water and be unable to sand control, and can not be direct
Be connected into completion tubular column and go into the well and use, and existing screen casing can only sand control can not control water, both can not combine well, so as to influence
The application and popularization of the steady oil tech of intelligent water-controlled.
Utility model content
