Abstract
The utility model provides an oil casing ring empty oil anti-theft check valve in an oil well, comprising a tubular sleeve (1); the upper part of the outer wall of the tubular sleeve (1) is fixedly provided with a support body (2); the support body (2) is provided with a channel; the tubular sleeve (1) under the support body (2) is sheathed with a sealed slide block (3); the sealed slide block (3) is provided with the channel; the tubular sleeve (1) under the support body (2) is provided with a spiral sliding way (4); the internal wall of the sealed slide block (3) is provided with a guide block which is positioned in the spiral sliding way (4). The check valve is positioned in the oil casing ring empty of the oil well, with good anti-theft performance, free from damage, without affecting normal production and monitoring of oil fields. Therefore, the oil casing ring empty oil anti-theft check valve solves the problem of stealing crude oil from the casing pipes of oil well fundamentally, thus decreasing loss of oil in oil fields.
Description
Technical field:
The utility model belongs to the used a kind of instrument in oil recovery field, oil field, particularly a kind of producing well oil jacket annular space guard against theft oil ball-and-seat.
Background technology:
As everyone knows, the oil well distributed areas are big, and well location is scattered, near the village, village, often stolen the lawless person's of crude oil destruction, steal from the sleeve pipe of producing well and put crude oil.Producing well guard against theft oil technology mainly concentrates on ground and well head part at present, metal anti-theft case, guard against theft oil plug, valve for guarding against theft and electronic anti-theft equipment etc. for example are installed, because anti-theft device is installed in ground, be cut easily, destroy and lose the effect of guard against theft oil, can not fundamentally solve the problem of producing well guard against theft oil.
Summary of the invention:
In order to solve the problem that exists in the background technology, the utility model provides a kind of producing well oil jacket annular space guard against theft oil ball-and-seat, this ball-and-seat is installed in the oil jacket annular space of producing well, theftproof performance is good, can be not destroyed, do not influence the ordinary production and the oilfield monitoring of producing well, fundamentally solve producing well and steal the problem of putting crude oil, reduce the oil field loss from sleeve pipe.
The technical scheme that the utility model adopted is: this producing well oil jacket annular space guard against theft oil ball-and-seat comprises tubular sleeve, tubular sleeve outer wall top is fixed with supporter, supporter is provided with passage, be with the sealing slide block on the tubular sleeve of supporter below, have spiral slide on the tubular sleeve outer wall of supporter below, sealing slide block inwall is equipped with guide pad, and guide pad places in the spiral slide.
This novel beneficial effect that has is: this novel employing jacket-type designs, and does not change the down-hole string structure of producing well, can satisfy the requirement of strength that ordinary production and operation are safeguarded.To not influence of producing well job execution.Do not influence the oil well monitor liquid level, not clear construction of influence and sleeve pipe gas collection.Have simple in structure, cheap, stable performance, the guard against theft oil time is long, and guard against theft oil is effective, can not be destroyed etc. advantage, fundamentally solved the problem of producing well sleeve pipe stolen, have popularizing application prospect widely.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of supporter among Fig. 1;
Fig. 3 is the vertical view of sealing slide block among Fig. 1.
Among the figure: the 1-tubular sleeve, the 2-supporter, 3-seals slide block, 4-spiral slide, 5-rubber seal packing, guide way under the 6-.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further specified: as shown in Figure 1, this producing well oil jacket annular space guard against theft oil ball-and-seat comprises tubular sleeve 1, tubular sleeve 1 outer wall top is fixed with supporter 2, supporter 2 is provided with passage, be with sealing slide block 3 on the tubular sleeve 1 of supporter 2 belows, sealing slide block 3 is provided with passage, have spiral slide 4 on tubular sleeve 1 outer wall of supporter 2 belows, sealing slide block 3 inwalls are equipped with guide pad, guide pad places in the spiral slide 4, sealing slide block 3 can rotate up or rotates descending along spiral slide 4, when sealing slide block 3 upwards slided to supporter 2, the effect of guard against theft oil was played in sealing supporter 2 upper channels and then sealing oil jacket space.Supporter 2 outer walls groove along the circumferential direction is built-in with rubber seal packing 5.
Remove for convenience this ball-and-seat in oil well casing, be fixed with down guide way 6 on tubular sleeve 1 outer wall of sealing slide block 3 belows, following guide way 6 is provided with passage.
The pressure reduction principle that producing well oil jacket annular space guard against theft oil ball-and-seat adopts liquid stream to form, after the well head sleeve valve is opened, liquid stream is up in the pit shaft, forms pressure differential up and down at guard against theft oil device sealing slide block 3, and it is up to promote sealing slide block 3, sealing slide block 3 is up along spiral slide 4 rotations on the tubular sleeve, contact shutoff producing well oil sets annular space, blocking-up oil flow channel with supporter 2, crude oil can not be emitted continuously from the sleeve valve on ground, plays the effect of guard against theft oil.
After the well head sleeve valve was closed, the oil jacket annular space is pressure balance up and down, and sealing slide block 3 relies on deadweight to fall after rise, can open the fluid course of oil jacket annular space again, did not influence that producing wellization is clear, liquid level monitoring and gas collection function.
Under producing well ordinary production situation, the passage of supporter 2, sealing slide block 3 and the passage of bottom guide way 6 are point-blank, sound wave can carry out liquid level monitoring by duct up and down, the number of channels of sealing slide block 3 is less than the number of channels on the supporter 2, when flowing on the liquid in the oil jacket annular space flows to like this, can form certain pressure reduction, promote sealing slide block 3 and move up, guarantee the sealing reliability of oil sets annular space.
All design has a guide angle on supporter 2 and guide way 6, can fall any more, pulls out motionless accident when preventing to remove the producing well down-hole string.
