Abstract
The utility model relates to a sand and oil leakage prevention device, consisting of an oil pipe coupling, a pin leaker, a sand storage, sieve pores, an oil drain pipe, a valve clack, a lockpin, a protective sleeve, a valve seat and an oil pipe. The oil pipe coupling is connected with the upper part of the protective sleeve through threads; the sand storage consists of the oil drain pipe and the oil pipe coupling; sieve pores are symmetrically arranged at the upper part of the oil drain pipe, wherein walls of the sieve pores are provided with holes, and the axis of the hole and the sieve pore surface form a 45-degree angle in the normal direction; the lower part of the valve clack is provided with the triangular lockpin; the valve seat is connected with the lower part of the protective sleeve through threads. The sand and oil leakage prevention device has the advantages that the structure is simple, the hydraulic pressure exerted on the pump in the production process is reduced, and the amount of leakage of the pump is reduced. The sand and oil leakage prevention device also has the advantages of anti-air lock, anti-sand clogging, environmental protection, higher pumping efficiency and longer service life of the oil pump.
Description
One, technical field:
The utility model relates to a kind of sand control draining protective device of oil pump production usefulness.
Two, background technology:
The oil field tubing pumps productions of recovering the oil of adopting of recovering the oil at present more, because crude oil and other thing in the tubing pump pump hanging tube can not leak in the well, pump plunger shaft stops up easily by the sandstone landfill when production operation, directly influences the application life and the oil well output of oil well pump.For this reason, we have developed a kind of sand control draining protective device, and it can also reduce to act on the head of liquid on the pump in process of production except that draining, reduce the pump leakage amount, have anti-gas lock, sand control card simultaneously, environmental protection, raising pump efficiency function.
Three, utility model content:
The utility model purpose is to provide a kind of sand control draining protective device, and it has solved the pump plunger shaft that exists in the prior art easily by the sandstone landfill, stops up, and directly influences the application life of oil well pump and the problem of oil well output.
The technical scheme that its technical problem that solves the utility model adopts is: sand control draining protective device is by tubing coupling (1); pin bleeder (2); sand storing machine (3); sieve aperture (4); drain mast (5); flap (6); lock pin (7); protective casing (8); pump seat (9); oil pipe (10) is formed; it is characterized in that: tubing coupling (1) and protective casing (8) top screwed connection; drain mast (5) constitutes sand storing machine (3) with tubing coupling (1); be provided with the sieve aperture (4) of symmetry on drain mast (5) top; have the hole on sieve aperture (4) wall; axially bored line and sieve aperture (4) surface normal direction is 45 degree angles; flap (6) bottom is provided with triangle lock pin (7), pump seat (9) and protective casing (8) bottom screwed connection.
The new beneficial effect of this practicality is, and is simple in structure, has the head of liquid that reduces in process of production to act on the pump, reduces the pump leakage amount, has anti-gas lock, sand control card, environmental protection, raising pump efficiency simultaneously, prolongs advantage such as oil well pump application life.
Four, description of drawings:
Accompanying drawing is the utility model overall structure schematic diagram.
Among the figure, 1, tubing coupling 2, pin bleeder 3, sand storing machine 4, sieve aperture 5, drain mast 6, flap 7, lock pin 8, protective casing 9, pump seat 10, oil pipe.
Five, the specific embodiment:
As shown in the figure; sand control draining protective device is by tubing coupling (1); pin bleeder (2); sand storing machine (3); sieve aperture (4); drain mast (5); flap (6); lock pin (7); protective casing (8); pump seat (9); oil pipe (10) is formed; it is characterized in that: tubing coupling (1) and protective casing (8) top screwed connection; drain mast (5) constitutes sand storing machine (3) with tubing coupling (1); be provided with the sieve aperture (4) of symmetry on drain mast (5) top; have the hole on sieve aperture (4) wall; axially bored line and sieve aperture (4) surface normal direction is 45 degree angles; flap (6) bottom is provided with triangle lock pin (7), pump seat (9) and protective casing (8) bottom screwed connection.
When sand control draining protective device is worked, connect oil pipe (10) on this protective device, lower linking tube formula oil well pump (constituting) by standing valve, travelling valve, plunger, the pump housing, during the operation of oil down-hole pump, utilize lock pin (7) that flap (6) is fixing, shutoff drain mast (5) is finished the oil well pump ordinary production; In the oil well production process, plunger is up, and flap (6) is up thereupon, and fluid column enters sand storing machine (3) along going out sieve aperture (4), and at this moment a small amount of sand carries out sedimentation here, can't fall back between plunger and the pump barrel, reduces the sand card.Fluid column is advanced into oil pipe (10) on continuing; Plunger is descending, and the descending thereupon and seat of flap (6) seals on the pump seat (9), makes that head of liquid acts on flap (6) bottom in the oil pipe; make it to act on oil well pump; reduce the pump upward pressure, improve the coefficient of fullness of oil well pump, prevent gas lock and finish protection oil well pump.
