Abstract

The invention belongs to the technical field of supporting equipment for oil production in oil fields, and in particular relates to a wellhead casing associated gas recovery device. The wellhead casing associated gas recovery device facilitates the use in oilfield production, increases the safety, reliability, environmental protection, and energy saving of the use, and the recovery rate of associated gas can reach 100%. The phenomenon of dripping and leaking has completely realized zero discharge and closed production, which has solved a series of problems such as the discharge of associated gas in the wellhead casing and the rise of the moving fluid level. A wellhead casing associated gas recovery device, comprising: a wellhead liquid removal filter connected to the wellhead casing; a vaporization filter; a gas compressor; an oil-gas separator; the inlet port of the oil-gas separator and the gas compressor The gas outlet of the oil-gas separator is connected with the gas phase outlet of the oil-gas separator and the casing gas recovery pipeline.

Description

technical field [0001] The invention belongs to the technical field of supporting equipment for oil production in oil fields, and in particular relates to a wellhead casing associated gas recovery device. Background technique [0002] In the process of oil well production, driven by formation pressure, oil flows from the bottom of the well along the wellbore from bottom to top. As the pressure gradually decreases, the associated gas dissolved in the oil will separate from the oil mixture and enter the annular space between the casing and the tubing to form casing gas. Traditional casing gas treatment mostly adopts the method of direct evacuation, which will cause waste of oil and gas resources on the one hand, and environmental pollution on the other. Therefore, it is urgent for those skilled in the art to provide a simple and reliable recovery device for processing casing associated gas. to solve the above problems. Contents of the invention [0003] The invention provi...
