Abstract
The utility model provides a ball plug air lift ball feeding hydraulic cylinder with double pistons applied in the ball plug air lift technical skill of the oilfield field. The ball plug air lift ball feeding hydraulic cylinder with double pistons comprises an oil pipe 1, a ball collecting device 2, a ball end plug 3, a piston cylinder 4, a double-acting piston 5, a liquid inlet 6 and a lift ball 7. The oil pipe 1 is connected with the ball collecting device 2 which is provided with the ball end plug 3, and the oil pipe is respectively sheathed with the piston cylinder 4 and the double-acting piston 5. The oil pipe is provided with the liquid inlet 6, and the ball collecting device 2 is provided with the lift ball 7. Under rated pressure, the reciprocating motion of the two-stage liquid cylinder is under different pressure differences, and the work is reliable. The ball plug air lift ball feeding hydraulic cylinder with double pistons satisfies the motion of a rubber ball from a low-pressure end to a high-pressure end.
Description
Technical field
The utility model is a device that is applied in the oil field pig gas lift technology, specifically, is pig gas lift double-piston release fluid cylinder.
Background technology
The artificial lift method of oil gas well is a lot, but still can not obtain satisfied selection in some cases.Along with the continuation of exploitation of oil-gas field, its strata pressure reduces gradually, uses present continuous gas lift technology to be difficult to reach the purpose of further raising recovery ratio.
Used pig gas lift piston release fluid cylinder can not guarantee under two different pressure conditions at present, separates the high-low pressure force environment, thereby the ball of restriction low-pressure end sends to high-pressure side.
Summary of the invention
The purpose of this utility model is to provide a kind of will separate the high-low pressure force environment under two different pressure conditions, guarantee the pig gas lift double-piston release fluid cylinder of the ball of low-pressure end to the high-pressure side transmission.
The utility model is achieved in that and comprises oil pipe 1, ball-collecter 2, ball plug 3, piston rod 4, two-way ram 5, inlet 6, lifting ball 7, oil pipe 1 is connected with ball-collecter 2, ball-collecter 2 is provided with ball plug 3, be with piston rod 4, two-way ram 5 on the oil pipe 1 respectively, inlet 6 is set on oil pipe 1, lifting ball 7 is housed on the ball-collecter 2.
The utility model also adopts following technical scheme:
This device adopts Y type dual string.
Piston 5 has through hole by the double containment combination between the double containment combination, when high-pressure side moved, double containment was separated height pressure to through hole all the time by low pressure.
Advantage of the present utility model is: under specified pressure, the reciprocating motion of two-stage fluid cylinder is reliable operation under different pressure differentials, satisfies ball in the motion of low-pressure end to high-pressure side.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, mainly form by mechanisms such as oil pipe 1, ball-collecter 2, ball plug 3, piston rod 4, two-way ram 5, inlet 6, lifting balls 7.By φ 90mm and the combination of φ 63mm piston diameter fluid cylinder, φ 90mm fluid cylinder is subjected to hydraulic coupling to finish impetus forward.φ 63mm piston is made up by double containment, between the double containment combination φ 40mm through hole is arranged, and when high-pressure side moved, double containment was separated height pressure to φ 40mm through hole all the time by low pressure.After φ 90mm fluid cylinder was laid down hydraulic coupling, φ 63mm piston was subjected to return original state under the effect of high-pressure side pressure.
The pig gas lift device is to adopt Y type dual string, injecting air-flow input airlifting ball as the alternate solid interface of gas-liquid, to realize stable slug flow state, can prevent effectively that liquid from falling after rise, thereby improve the stable type of gaslift process, significantly reduce the alternate slippage loss of gas-liquid, reduce gas injection rate, improve its lifting efficiency.The effect of pig gas lift double-piston release fluid cylinder is that the airlifting ball time interval is on request dropped in the gas injection tubing string, and the power of its injection is the pressure effect of hydraulic pressure automatic control system.After the ball propelling, by valve piston power under the well head pressure effect fluid cylinder is resetted, wait for pitching next time.
This device has carried out field trial, work in test and work well, under the control of pig gas lift technology pitching time control Hydraulic Station, promote the release of double-piston release cylinder by hydraulic pressure and advance the gas injection tubing string, automatically throw a ball per half an hour, and formation water is effectively discharged in the pitching that circulates so repeatedly, reach the purpose that improves gas production, respond well.
