Synchronous rotary drainage and gas recovery device for gas well mouth

Abstract

The invention discloses a synchronous rotary drainage and gas recovery device for a gas well mouth. The device comprises a base, a first synchronous rotary pump set and a second synchronous rotary pump set are symmetrically arranged on the base, an intermediate buffer tank and a discharge buffer tank are mounted between the first synchronous rotary pump set and the second synchronous rotary pump set, a third buffer tank and a fourth buffer tank are arranged between the middle buffer tank and the discharge buffer tank, a first buffer tank and a second buffer tank are mounted on one side of the first synchronous rotary pump set, an oil cooling device is mounted on one side of the second synchronous rotary pump set, and each pump set is in communication with the corresponding tank body through a connecting pipeline.

Description

technical field [0001] The invention belongs to the technical field of gas field wellhead stimulation equipment, and relates to a synchronous rotary drainage gas recovery device for the wellhead of a gas well. Background technique [0002] Most gas wells contain water or condensate. When the gas well pressure and production decrease, the gas cannot effectively carry out the liquid and the liquid begins to accumulate in the pipe string. The gradual accumulation of liquid in the gas well further leads to reduced production, shortened production time, and even shut down production. [0003] At present, the existing domestic technologies such as foam and plunger drainage and gas recovery are all measures to use the energy of the gas well itself to drain and recover gas. Contents of the invention [0004] The object of the present invention is to provide a synchronous rotary drainage and gas recovery device for the wellhead of a gas well, which can supplement energy to the gas...
