Problems solved by technology
Due to the inadequacy of the existing oil production process design and related supporting facilities, the natural gas produced from the casing has no special gas transmission pipeline to transport it, so the natural gas produced at the wellhead of the oil well cannot be transported to the gathering and transportation station
This part of natural gas cannot be effectively utilized

Oil well casing gas recovery and oil-gas mixed eddy current transportation system for crude oil transportation is a recovery and transportation technology for wellhead crude oil and casing natural gas. Realize the uniform transportation of oil and gas in the same pipeline, reduce the waxing and clogging phenomenon in crude oil transportation, realize the mixed transportation of oil and gas by recovering the natural gas produced in the crude oil extraction process and pressurize it, and realize the maximum benefit of crude oil extraction. Pressurized conveying, through the optimization of the flow state of the vortex mixer, realizes the guarantee of efficiency and safety through fully automatic work control and safety protection.
Description
technical field [0001] The invention relates to the technical field of casing gas recovery and crude oil transportation in oil exploitation, in particular to an oil-gas mixed eddy current transportation system for casing gas recovery of oil wells and crude oil transportation. technical background [0002] In the current crude oil extraction process, since the output of natural gas in the oil well casing is not very large during crude oil extraction, the output is unstable in addition. Therefore, generally only the oil pipeline is laid to the gathering station. Due to the inadequacy of the existing oil production process design and related supporting facilities, the natural gas produced from the casing has no special gas transmission pipeline to transport it, and the natural gas produced at the wellhead of the oil well cannot be transported to the gathering and transportation station. This part of natural gas cannot be effectively utilized. Generally, it is sent to the flar...
