Abstract

The invention provides a high-precision real-time online multiphase flowmeter for oil fields. The multiphase flowmeter includes a safety valve, a gas-liquid separator, a float oil-gas three-way regulating valve, a liquid flowmeter, a pressure gauge, a water content measuring instrument, a gas flowmeter, valves and pipelines. The gas-liquid separator separates the medium from gas to liquid; the float oil-gas three-way regulating valve ensures the measurement accuracy of the liquid flowmeter and gas flowmeter; the moisture content measuring instrument uses a differential pressure transmitter to measure the moisture content in the liquid. The multiphase flowmeter of the present invention can measure the moisture content of liquids in real time, accurately, quickly and effectively, and the measurement error of the moisture content is less than ±2%. Then, according to the measurement results of the liquid flowmeter and the gas flowmeter, through computer processing, the oil and water can be obtained. , Gas production value. The multiphase flowmeter of the invention can implement production optimization, improve oilfield work efficiency, save oilfield production and development costs, and is beneficial to oilfield management and process control.

Description

technical field [0001] The invention belongs to the field of oilfield metering, and in particular relates to a high-precision real-time online multiphase flowmeter for oilfields. Background technique [0002] In the actual production process of oilfields, how to measure oil, water, and gas production in real time, accurately, quickly and effectively is very important: on the one hand, it can implement production optimization, improve oilfield work efficiency, and save oilfield production and development costs; on the other hand , which is beneficial to oilfield management and process control. [0003] In the actual production process of oil fields, there are many types of multiphase flowmeters for gas, oil, and water, and there are many related patents. However, most of the multiphase flowmeters in the market currently have low measurement accuracy, especially the measurement accuracy of water cut. The error reaches ±10%. For many oil wells in the middle and late stage of ...
