Embodiment Construction

[0010] figure 1 , 2 Specific embodiments of the invention are given.

[0011] An oil well stimulation environmental protection device, which has a lower casing 14 connected with oil well tubing and an upper casing 1 connected with a pumping unit, an outer casing 17 is connected between the upper casing 1 and the lower casing 14, and the outer casing The inner diameter of 17 is 2-3 times the inner diameter of the upper casing 1 and the lower casing 14; the upper casing 1 and the outer casing 17 are sealed and connected through flanges 3 and 4; the middle part of the outer casing 17 is connected with an oil storage pipe 18, and the outlet of the oil storage pipe 18 Connect the oil outlet pipe interface 20 on the top. In the outer casing 17, there is a check valve mechanism that reciprocates up and down with the sucker rod of the pumping unit. The one-way valve mechanism includes a flange 12, the flange 12 is installed on the sucker rod through the clip 9, and there is an oil ...

Abstract

The invention relates to an oil well yield-increasing environmental protection device for wellhead equipment, belonging to the oil drilling and excavation technical field. The device is provided with a lower casing connected with an oil pipe of an oil well and an upper casing connected with an oil extractor. An outer casing is connected with between the upper casing and the low casing; the inner diameter of the outer casing is twice to three times that of the upper casing or that of the lower casing; the upper casing is in sealed connection with the lower casing through a flange; an oil-reservoir pipe is communicated with the middle part of the outer casing; and an outlet of the oil-reservoir pipe is connected with an entrance of the an oil outlet pipe. The outer casing is thickened to leave an enough oil-reservoir space inside the outer casing, so that crude oil can not reach and exceed the oil-reservoir space, thereby putting an end to the phenomena of the crude oil leakage and the replacement of used tight head. The outer casing is provided with a one-way valve mechanism which makes reciprocating movement up and down with a sucker rod of the oil extractor, that is, residual energy of the sucker rod is utilized to drive the sealed one-way valve to move up and down, thereby playing a role in extracting assistedly and achieving the effect of increasing yield.

Description

technical field [0001] The invention belongs to the technical field of oilfield equipment, in particular to an additional device on the joint between a pumping unit and a wellhead. Background technique [0002] Existing pumping units utilize sucker rods to pump crude oil into oil tanks from oil wells through oil pipes. The oil rod reciprocates up and down in the oil pipe. In order to prevent crude oil from leaking from the gap between the oil rod and the oil pipe, a sealing packing is installed at the end of the oil pipe. The root not only requires extremely high sealing performance, but also the packing is easily damaged. Generally, the packing of the pumping unit needs to replace the sealing ring regularly. Even so, the leakage of crude oil cannot be prevented. in addition. How to improve the efficiency of the existing pumping unit is also a major problem. At present, we can only start with improving the operating frequency of the pumping unit, and there is no other mea...
