Abstract

The invention belongs to the technical field of oil-gas-water three-phase flow, and particularly relates to a method for simultaneously monitoring oil-gas-water three-phase flow, wherein the method comprises a liquid inlet pipeline and a monitoring pipeline, a liquid inlet mechanism is arranged below the liquid inlet pipeline, and the liquid inlet mechanism controls the flow of fluid in the liquid inlet pipeline; and the monitoring pipeline is arranged on one side of the liquid inlet mechanism, monitoring components are arranged in the monitoring pipeline and on the surface of the monitoring pipeline, and the monitoring components monitor the oil-gas-water content of fluid flowing into the monitoring pipeline. According to the method for simultaneously monitoring the oil-gas-water three-phase flow, monitoring of oil-gas-water three-phase holdup is achieved through an oil-gas-water three-phase holdup sensor by means of capacitance conductivity and an ultrasonic sensing technology, and the overall flow in a monitored pipeline is obtained through a flow sensor which is a vortex street sensor. The oil-gas-water three-phase holdup sensor and the flow sensor are connected to a host through an oil-gas-water three-phase holdup sensing signal line and a flow sensing signal line, and the flow of the oil phase, the flow of the gas phase and the flow of the water phase can be obtained through analysis software on the host.

Description

technical field [0001] The invention relates to the technical field of oil-gas-water three-phase flow, in particular to a method for simultaneously monitoring oil-gas-water three-phase flow. Background technique [0002] With the continuous improvement of our country's scientific and technological level, our country has achieved world-renowned achievements in all walks of life, especially in the petroleum and petrochemical industry. In the petroleum and petrochemical industry, the measurement of oil, gas and water has always been an important means. Oil, gas and water three-phase measurement can evaluate oil and gas production efficiency and provide guidance for oil and gas production, especially the measurement of oil, gas and water three-phase flow is more important. [0003] At present, for the measurement of the three-phase flow of oil, gas and water, usually only the overall flow of oil, gas and water can be obtained. To obtain the respective flow rates of the three pha...
