Description
Technical Field
The utility model belongs to the technical field of the gas lift valve, concretely relates to pressure gradient adjustable unconventional gas lift valve.
Background
The gas lift is not limited by the depth of an oil well, injected gas can pass through gas lift valves at all levels from top to bottom successively and deeply enter liquid, so that the weight of the liquid above the bottom of an oil pipe is lightened, and the back pressure of the oil layer is reduced, thereby ensuring the smooth and continuous production of the oil well; the diameter of the pipe is small, the pipe can be customized at 28-38mm, the material is sulfur-proof, and the tensile strength is high.
However, the pressure gradient of the conventional gas lift valve cannot be adjusted, and for different working environments and working requirements, only a single pressure gradient is adopted for working, so that the working efficiency is difficult to guarantee, and even a plurality of potential safety hazards exist.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a pressure gradient adjustable unconventional gas lift valve to solve the problem that proposes in the above-mentioned background art, the pressure gradient of current gas lift valve all can't be adjusted, to different operational environment and work demand, only adopts single pressure gradient to work, and work efficiency is difficult to guarantee, has a great deal of potential safety hazard's problem even.
In order to achieve the above object, the utility model provides a following technical scheme: the unconventional gas lift valve with the adjustable pressure gradient comprises an upper valve body, a middle valve body and a lower valve body which are sequentially connected from top to bottom, wherein mutually communicated channels are formed in the upper valve body, the middle valve body and the lower valve body; the two ends of the middle valve body are respectively sleeved with a pressure adjusting ring and a reverse circulation assembly, and the middle valve body is further sleeved with an elastic piece located between the pressure adjusting ring and the reverse circulation assembly.
Preferably, the middle valve body is provided with a through hole, one end of the through hole is communicated with the channel, and the reverse circulation assembly covers the other end of the through hole.
Preferably, sealing rings sleeved on the middle valve body are distributed between the reverse circulation assembly and the middle valve body.
Preferably, the sealing rings are provided with two groups, and the two groups of sealing rings are respectively positioned on two sides of the through hole.
Preferably, a sealing ring sleeved on the middle valve body is also distributed between the upper valve body and the middle valve body.
Preferably, the elastic member is a spring.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a pressure gradient of gas lift valve can adjust, and opening pressure realizes through adjustable ring compression spring, and work efficiency improves greatly, uses safelyr, has guaranteed the reliable of work and has gone on to with low costs, suitable popularization.
