Description
Technical field
The utility model relates to a kind of sand control gas and oil separating plant.
Background technology
While pumping operation under oil well, the foreign material such as gravel easily enter in oil, in order to stop the foreign material such as gravel to enter in oil, at present, generally take sand device include a sand retention pipe, the inwall of sand retention pipe is provided with oil seepage hole, its shortcoming is the obstruction that oil seepage hole is easily subject to sandstone, affects oil impregnate amount.In addition, existing sand retention pipe stops that the foreign material such as gravel that fall finally drop down onto tail pipe, and through after a period of time, the foreign material of accumulation fill up tail pipe, and sand retention pipe covers the most at last, results in blockage, and affects Petroleum Production.
Summary of the invention
The utility model is exactly for existing the deficiencies in the prior art, and a kind of new technical thought is provided.The utlity model has the function of sand control, gas-tight multi-phase separation, thereby improve pumping efficiency, extend the application life of oil well pump, increase oil recovery economic benefit.
The technical scheme that the utility model provides is:
Self-cleaning sand control gas and oil separating plant, be arranged at oil well pump below, vent connection lower end connects outer tube, outer tube top is provided with sieve aperture, vent connection lower end is also connected with interior sand-proof pipe, interior sand-proof pipe is positioned at outer tube, interior sand-proof pipe bottom is provided with sieve aperture and lower end sealing, outer tube lower end connects valve joint, valve joint below connects ball receiving groove, between ball groove and valve joint, clamping has valve seat, ball groove lower end is provided with gland, on gland, arrange porose, adjusting screw(rod) is threaded and passes gland, the upper end of adjusting screw(rod) connects guide pad, on guide pad, be fixed with spring, spring upper end compresses valve ball, valve ball top compresses valve seat.
Concrete, in outer tube, on sand-proof pipe excircle, be provided with flight, described flight is positioned at the top of sieve aperture on the below, sand-proof pipe of sieve aperture on outer tube.
Preferably, on interior sand-proof pipe sieve aperture place excircle, be provided with wrapping wire.
Concrete, ball groove lower end is connected with lower contact.
Concrete, on vent connection, be provided with inclined hole and be communicated with the space outside annulus and outer tube between outer tube and interior sand-proof pipe.
Concrete, on vent connection, be provided with the screw for sand-proof pipe in fixing.
The utility model, for sand control, gas-tight and gas-liquid sand multi-phase separation, supports the use with oil well pump in the oil well containing sand, gassiness.In oil pumping process, the utility model adopts fluid mechanics principle to manufacture and design, fluid is entered in this device by outer tube sieve aperture, through flight, realize gas, sand, liquid automatically separated, isolated gas is discharged by top inclined hole, liquid enters interior sand-proof pipe through the interior sand-proof pipe sieve aperture at flight and wrapping wire place, and the fluid of rotation can also wash away the remaining sand on interior sand-proof pipe tube wall simultaneously, reaches the object that oneself cleans.In the situation that fluid spiral moves, because the proportion of sand is larger, sand can sink voluntarily, and by valve ball, place falls, thereby realizes sand settling function.

The specific embodiment
As shown in the figure, self-cleaning sand control gas and oil separating plant, is arranged at oil well pump below.Vent connection lower end connects outer tube, and outer tube top is provided with sieve aperture, and vent connection lower end is also connected with interior sand-proof pipe, and interior sand-proof pipe is positioned at outer tube, and interior sand-proof pipe bottom is provided with sieve aperture and lower end sealing.On vent connection, be provided with inclined hole and be communicated with the space outside annulus and outer tube between outer tube and interior sand-proof pipe.On vent connection, be provided with the screw for sand-proof pipe in fixing.On sand-proof pipe excircle, be provided with flight in outer tube, described flight is positioned at the top of sieve aperture on the below, sand-proof pipe of sieve aperture on outer tube.On interior sand-proof pipe sieve aperture place excircle, be provided with wrapping wire, be about to selected stainless steel steel wire winding at the sieve aperture place of interior sand-proof pipe.
Outer tube lower end connects valve joint, valve joint below connects ball receiving groove, between ball groove and valve joint, clamping has valve seat, ball groove lower end is provided with gland, arranges porosely on gland, and adjusting screw(rod) is threaded and passes gland, the upper end of adjusting screw(rod) connects guide pad, on guide pad, be fixed with spring, spring upper end compresses valve ball, and valve ball top compresses valve seat.Ball groove lower end is connected with lower contact.
When the oil well pump of top is worked, the oil of oil reservoir enters annulus between outer tube and interior sand-proof pipe by the sieve aperture of outer tube, under the effect of flight, oil screw is descending, by wrapping wire place sieve aperture, enter interior sand-proof pipe, rise afterwards, by oil well pump, be promoted to ground.
Oil is under screw state, and the foreign material such as the gravel that in oil, proportion is larger sink, when the weight of gravel reaches particular value, gravel presses down valve ball, and valve ball is separated with valve seat, forms sinking passage, gravel falls to below, falls in the tail pipe of lower contact below connection, or directly falls into oil reservoir.
Oil is under screw state, and the gas in oil rises, by being discharged by top inclined hole.Oil is under screw state, and the foreign material such as gravel that the outer wall of interior sand-proof pipe and wrapping wire place can be adhered to wash away.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the field are to be understood that: still can modify or part technical characterictic is equal to replacement the specific embodiment of the present utility model; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
