Multi-phase flow oil-water-gas monitoring device suitable for single well

Abstract

The invention relates to the technical field of single-well multiphase flow, and discloses a single-well multiphase flow oil-water-gas monitoring device which is characterized in that a separation chamber is formed in the left side of the upper portion of a mounting shell, an annular filter screen is rotatably arranged in an inner cavity of the separation chamber, and a scraping plate is movably arranged in the inner cavity of the separation chamber; the upper surface of the scraper is in movable contact with the top surface of the inner ring of the filter screen, and a driving chamber is formed in the right side of the upper part of the mounting shell. When the oil-water-gas monitoring device suitable for the single well multiphase flow is used, a servo motor is arranged to drive a filter screen to rotate, and an electric rotating disc drives a driving disc to rotate, so that a scraping plate is driven to do horizontal reciprocating motion, and impurities attached to the inner wall of the filter screen after crude oil is filtered can be scraped and cleaned; therefore, the problems of poor monitoring effect and low accuracy caused by blockage of a filter screen due to high viscosity and many impurities of crude oil are avoided.

Description

technical field [0001] The invention relates to the technical field of single well multiphase flow, in particular to an oil, water and gas monitoring device suitable for single well multiphase flow. Background technique [0002] Single-well multi-phase flow oil-water-gas monitoring is a device for oil, gas, and water three-phase flow measurement when crude oil is transported in pipelines. It is widely used in onshore oil fields and offshore oil industries. It is an essential key equipment for process parameter control. Many newly developed oilfields are economical marginal oilfields, which cannot bear the high costs caused by traditional separation techniques, and multiphase flowmeters can save a lot of money, because using it will There is no need to install separators or common processing devices for several oil fields. In terms of oil well management, multiphase flowmeters can provide continuous data output and give valuable information about oil well dynamics, so that pr...

Problems solved by technology

[0003] When the common oil-water-gas monitoring device is in use, the crude oil is directly extracted from the transportation pipeline to the flow meter for monitoring by using the pump connecting the pipeline. There are many impurities in the crude oil, and when the flow is measured, it will collide with the flow meter probe and affect the measurement. Stability, although a filter is installed at the pump to filter the impurities in the crude oil, but the viscosity of the crude oil is large and carries a lot of impurities, which will easily block the filter, resulting in poor monitoring effect and low accuracy, and the equipment needs to be disassembled For the problem of cleaning the filter screen, it cannot meet the working requirements of oil-water-gas monitoring. Therefore, a multi-phase flow oil-water-gas monitoring device suitable for single well is proposed.
