Abstract
The utility model discloses a resin sand screen not only is applicable to the construction of the ordinary oil well sand control of petroleum industry, is particularly useful for big inclination sand control construction, if: the construction of loose sand rock oil reservoir highly deviated well sand control is dredged to high shale. This sand screen includes central parent tube and resin sand body, is equipped with liquid flow hole on the body of central parent tube, the both ends branch maybe top connection and lower clutch. The body outer wall welding water conservancy diversion brace rod of center parent tube concreties the resin sand body in the outside of central parent tube, and the protection network concreties the outer wall at the resin sand body. Improve the intensity of sand screen and the protect function who goes into the in -process down, prolonged the sand control cycle. Use the utility model discloses the sand control can effectively reduce the manufacturing cost and the use cost of sand screen, has solved the damaged problem of highly deviated well sand control screen, has fine result of use and economic benefits.
Description
Technical field
This utility model is the down-hole sand-proof tool of oil exploitation, particularly a kind of resin sand screen, is applicable not only to general
Logical sand control construction, is particularly suited for High angle sand control construction, such as：High shale content loose sand oil accumulation high angle hole sand control
Construction.
Background technology
Sensitivity loose sand oil accumulation abundant in petroleum deposits, but deeply make sand production more tight with oil field development
Weight.At present, conventional sand control measure mainly has chemical sand control, mechanical sand control and composite sand prevention.Due to sensitivity loose sand oil
Hide presence shake out seriously, shale content high, the poor problem of sorting, especially for high angle hole, be faced with sand control at present excessive
Or the following contradiction of anti-incessantly sand：1. chemical sand control does not affect oil well productivity, but because of sand control low intensity, the sand control life is short,
Cause the frequent operation of oil well, increase production cost；2. the sand control method such as metal sand screen sand control, filling anti-sand sand control success rate
Height, sand controlling result is good, but because the pollutant such as shale invade, after being easily caused sand control, blocking fall is produced；3. composite sand prevention is suitable for
Scope is wide, the sand control life is long, but its complex process, relatively costly, reduce oil well productivity；4. resin sand screen, corundum filter
The sand control method construction of sandpipe is simple, low cost, production capacity is affected little, but its quality is more crisp, in transportation and Holes of Complicated Wells
Fragile under the conditions of cylinder, success rate is relatively low, applies in general to the oil well that hole angle is less than 30 °, hole angle is more than to 30 ° of oil
, because of wellbore trajectory impact, easily sand control screen breakage, leads to sand control to lose efficacy in well.
The shortcoming that resin sand screen exists at present：The center base tube of resin sand screen is processed respectively with resin sand body at present,
Later stage fits together, and there is gap, cracky.Center base tube is 4 meters of long oil pipes, exists partially because center base tube is cylindrical
Difference, can pass through center base tube, the internal diameter at least big 1mm of Yao Bi center base tube external diameter of sand body for guarantee sand body.Sand body is by 3 sections
, though there being male and female buckle structure, after the completion of 3 meters of sand body integrated connections, can there are different journeys in 1 meter of sand body gauze and epoxy glue consolidation
The not coaxial phenomenon of degree, various clearance condition all can exist, and causes the anti-ability of colliding with of sand body, sometimes in transportation just
There is breakage, sand control success rate of therefore going into the well is low.For this reason, scene needs one kind to can effectively solve the problem that high angle hole sand control screen
The sand control screen of damaging problem, extends the sand control life, improves sand controlling result.
Content of the invention
The purpose of this utility model is to provide a kind of resin sand screen, can effectively solve the problem that high angle hole sand control screen is damaged
Problem, reduce sand control cost, extend the sand control life, improve sand controlling result.
Technical solution of the present utility model is：A kind of resin sand screen includes center base tube and resin sand body, center
It is top connection and lower contact respectively that the body of base tube is provided with liquid flow hole, two ends.The tube wall welding water conservancy diversion of center base tube props up
Support muscle, resin sand body is fixedly arranged at the outside of center base tube, protection network is fixedly arranged at the outer wall of resin sand body.
This utility model compared with prior art, has following beneficial effect：This utility model sets on the base tube of center
Put water conservancy diversion brace rod to be consolidated with resin sand body, improve the intensity of sand screen, set in the outside of resin sand body simultaneously
Put protection network, the defencive function during improve down, extend the sand control cycle.This sand screen employ overall processing,
Resin sand body and cementation and formation technique of center base tube, it is to avoid gap, improve its intensity.Water conservancy diversion brace rod is spiral lamina
Shape body is welded on the outside of center base tube, and resin sand body one-shot forming is fixedly arranged above the base tube of center, because inside has water conservancy diversion to prop up
Support muscle, further enhancing the consolidation strength of resin.Protection network uses the metal sleeve in densely covered oblique effluent hole, can make ground
Layer fluid is taken a devious route, it is to avoid direct erosion shield net and the phenomenon of resin sand body that perpendicular flow causes, extends filter sand
The usage cycles of pipe.Anticollision effect, equipped with baffle plate, is played in the upper and lower both sides of protection network to resin sand body, thus overall antidetonation, anti-
Fall, crush resistance strength is high, adapt to the construction requirement of high angle hole completely.This device maximum lower going-into-well oblique angle is up to 65 degree.Additionally,
Resin sand body is always according to the median grain diameter of reservoir sand, theoretical in conjunction with sand control, adjusts the sand block precision of this sand screen, makes resin
Sand body is difficult by less gravel paste extremely, can keep high permeability for a long time.Using this utility model sand control, can effectively reduce filter
The manufacturing cost of sandpipe and use cost, solve the problems, such as that high angle hole sand control screen is damaged, reduce sand control cost, extend anti-
Sand effect duration, improve sand controlling result, there is good using effect and economic benefit.
Brief description
Fig. 1 is structural representation of the present utility model.
