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

Abstract

A vortex oil and gas mixed delivery system with a function of casing natural gas recycling and crude oil delivering for oil wells relates to the recycling and delivering technology of casing natural gas and crude oil at wellheads and is applied to recycling casing natural gas, reducing kinematic viscosity in crude oil delivery, realizing uniform delivery of the natural gas and the crude oil in the same pipeline and reducing wax precipitation and blockage in crude oil delivery during crude oil exploration. By recycling the natural gas generated during crude oil exploration and pressurizing, the crude oil and the natural gas can be delivered mixedly, benefit of crude oil exploration is maximized, benefits and safety are guaranteed by the aid of pressurizing delivery of a gas delivery pump, flow-state optimization of a vortex mixer, full-automatic working 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...
