Oil-gas multi-phase separation continuous metering device

Abstract

The invention discloses an oil-gas multi-phase separation continuous metering device. The oil-gas multi-phase separation continuous metering device comprises a separation tank, a gas outlet pipeline and a control cabinet, wherein an oil-gas separation element and a water bag are arranged in the separation tank, and an intelligent magnetic flap liquid level meter which communicates with the separation tank up and down is arranged on the outer side of the separation tank; an oil inlet pipeline and a confluence pipeline are further arranged on the separation tank, and an anti-overflow device is arranged on the confluence pipeline; the gas outlet pipeline communicates with the upper part of the separation tank and the confluence pipeline, and a temperature transmitter, a pressure transmitter and a liquid pressing valve are arranged on the gas outlet pipeline; and the oil inlet pipeline is connected with a well selection device, and the control cabinet is connected with the well selection device, the magnetic flap liquid level meter and the liquid pressing valve and is used for well selection, data remote transmission and remote monitoring. According to the oil-gas multi-phase separation continuous metering device, the anti-overflow device, the intelligent magnetic flap liquid level meter, the pressure transmitter and the temperature transmitter on the gas outlet pipeline are matched with a metering program to realize the metering of a gas phase and a liquid phase without a single-phase instrument, the operation is simple, and the problems of regular calibration of the instrument, intermittent liquid feeding and overflow of the tank due to large fluctuation of the liquid feeding amount are solved.

Description

technical field [0001] The invention relates to the technical field of oil and gas metering, in particular to an oil and gas multiphase separation continuous metering device. Background technique [0002] Oil and gas metering refers to the measurement of oil and gas flow. It is mainly divided into two types: oil well production measurement and external flow measurement. Oil well production measurement refers to the determination of the oil and gas produced by a single well. It is the key data for oil well management and mastering the dynamics of oil layers. It is the first-hand data for dynamic analysis of reservoirs, which directly affects the reservoir The direction of development, so the accuracy of oil and gas measurement is particularly important. [0003] Due to the influence of complex factors such as the nature of crude oil, the difference in water content and gas content, and the irregularity of produced liquid, there are problems in the actual application of oil ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is that the existing oil well metering device is easily affected by various factors, prone to tank overflow, and the workload of instrument verification in remote areas is large, which affects the normal production order.
