Abstract

Disclosed is an oil and gas separation device for oil well metering. The oil and gas separation device for oil well metering comprises an oil and gas separator and a liquid level measuring device. An oil inlet is formed in the middle of the side of the oil and gas separator, a gas exhaust outlet is formed in the top of the oil and gas separator, and an oil discharging outlet is formed in the bottom of the oil and gas separator. A gas exhaust pipe is connected to the gas exhaust outlet, an oil discharging pipe is connected to the oil discharging outlet, and an oil inlet pipe is connected to the oil inlet and stretches into the oil and gas separator. The liquid level measuring device comprises a vertical pipe and liquid level meters, wherein the liquid level meters are arranged in the vertical pipe, the vertical pipe is communicated with the oil and gas separator through two parallel connecting pipes, the two connecting pipes are arranged in a mode that one connecting pipe is arranged on the upper portion, and the other connecting pipe is arranged on the lower portion, and control valves are arranged on the connecting pipes. According to the invention, separation metering of oil and gas can be rapidly conducted, the oil and gas metering accuracy is high, and the measuring process is simple and rapid. Due to the fact that environmental data are acquired through a sensor so as to control the measuring opportunity, the influence of the environment on oil and gas metering is reduced, and the accuracy is improved. The oil and gas separation device for oil well metering has the advantages of being simple and compact in structure and convenient to use.

Description

technical field [0001] The invention relates to the technical field of oil and gas metering, in particular to an oil and gas separation device for oil well metering. Background technique [0002] With the development of industry and the progress of society, people's energy consumption continues to increase, and oil has become the primary choice of power energy. As a developing country, China, the crude oil industry has become the energy material that China relies on for development. , which puts forward higher and higher requirements on the oil extraction process. [0003] In the entire development and production process of an oil field, each oil well is a very important element. Through the accurate measurement of the output of each oil well, the evaluation of the entire oil field can be made to realize scientific production and optimize it. [0004] Real-time and accurate measurement of individual oil well production and related data of oil well work will provide a very i...
