Abstract

The invention discloses an adjustable constant-pressure anti-backflow type sleeve gas recovery device. The adjustable constant-pressure anti-backflow type sleeve gas recovery device comprises a first tubular body, a first one-way valve, a second tubular body, a connecting body, a second one-way valve and a pressure adjusting mechanism; the first one-way valve is arranged at the outlet end of the first tubular body; the second tubular body is arranged above the first tubular body, and the second tubular body communicates with the first tubular body; the outlet end of the connecting body is arranged in one end of the second tubular body; the second one-way valve is arranged in the second tubular body, and the second one-way valve is connected with the outlet end of the connecting body; the pressure adjusting mechanism is arranged at the other end of the second tubular body, and the pressure adjusting mechanism is in transmission fit with the second one-way valve.

Description

technical field [0001] The invention belongs to the technical field of oil well casing gas recovery, and in particular relates to an adjustable constant-pressure anti-backflow type casing gas recovery device. Background technique [0002] During the production process of oil production wells, free gas, partially dissolved gas and other casing gases will overflow from the casing pipes of oil production wells. The nature of this casing gas is the same as that of natural gas and can be directly burned. However, due to its small output, it is not suitable for industrial exploitation. The collected value. [0003] At present, most of this kind of jacket gas is ignited on the spot with a torch or directly released into the atmosphere for treatment. Such an operation is a waste of resources on the one hand and pollutes the environment on the other hand. Contents of the invention [0004] The purpose of the present invention is to provide an adjustable constant pressure anti-back...
