Oil layer respirator

Abstract

The invention provides an oil layer respirator capable of increasing yield of an oil well through a multiple composite mode. An upper joint is connected with a damping chamber outer pipe, a damping spring seat, a closed chamber outer pipe, a damping sliding body, a lower liquid passing board and a lower joint. An upper liquid passing board is connected with a sealing plunger, a valve body seat and a stop sliding body. The valve seat is provided with a valve body, a damping spring is mounted between the damping chamber outer pipe and the sealing plunger, and an elastic rubber cylinder between a limiting sliding body and the damping sliding body. When the pressure on the valve body raises, the elastic rubber cylinder and an oil layer sleeve are sealed and the elastic rubber cylinder move downwards to impact and pressure the oil layer. When the pressure on the valve body reduces, the elastic rubber cylinder can move upwards to suck and reduce pressure of the oil layer. A pulsation breathing effect can repeatedly affect on the oil layer to raise the yield of an oil well. The oil layer respirator can work under the well for a long time with no external factors, so the oil layer respirator is energy saving, environmental friendly, safe and high in efficiency.

Description

technical field [0001] The invention belongs to the technical field of oil exploitation, and relates to an oil layer respirator which relies on the energy of the oil well itself to generate pressure pulsation respiration on the oil layer, thereby increasing the output of the oil well. Background technique [0002] In order to increase the production of oil wells, various production stimulation measures have been implemented on the mine field to improve the fluid seepage environment in the oil layer, which can be summarized into the following categories: one is to create fractures in the formation to improve the conductivity of the formation; the other is to plug the oil layer Pores change the seepage path of fluid in the oil layer; the third is to unblock the oil layer and dredge the seepage channel of the fluid; the fourth is to reduce the viscosity of the fluid in the oil layer to reduce the seepage resistance of the fluid. The main disadvantages of various production stim...

AI Technical Summary

Problems solved by technology

The main disadvantages of various production stimulation technologies are the single function and limited stimulation effect. If the oil layer is not clearly understood, the technical effect will be greatly reduced, and even cause side effects. To accurately understand the oil layer requires a lot of technical and personnel costs, and most wells We all know it's unrealistic

At the same time, in view of the multiple production reduction reasons of oil wells, poor applicability of production stimulation technology, short effective time, poor reuse effect, high implementation cost, high labor intensity of on-site operations, complex construction equipment, potential safety hazards, damage to oil layers or pollution of the environment, etc. is an unavoidable fact
