Description

technical field [0001] The invention belongs to the technical field of oil production, and relates to a single-well oil measuring and production measuring system and production measuring method in a metering (valve group) room, in particular to a magnetic flap liquid level meter on-line rapid single Well measurement and oil production measurement method. Background technique [0002] At present, in oil production, the pipelines of several oil wells are usually connected into a metering (valve group) room, and the pipelines of a single (oil) well usually include oil return (crude oil production) pipelines and water-mixed pipelines, where water-mixed The pipeline is used to direct the mixed water to the wellhead of the single well through the water mixing valve of the single well, which is used for gathering and transporting heat tracing of crude oil to prevent the precipitation of paraffin in the crude oil. ) to the oil return header and flow to the combined station; at the ...

Problems solved by technology

[0004] The current metering (valve group) room is usually built for a long time. The pipelines and equipment in the metering (valve group) room are usually analog instruments and manually operated valves. Due to the nature of their work, large-scale transformation has become Automated instruments and automatic actuators are relatively difficult. Therefore, the oil production measurement in the metering (valve group) room can only be done manually by oil production workers. It usually takes 40 minutes to several hours to reach the above-mentioned liquid level when the liquid output of a single well is low. During these waiting times, oil producers need to monitor the liquid Position and synchronous timing, the work content is boring and error-prone, and due to subjective reasons, the measurement duration and the accuracy of the liquid level height also have large errors

[0005] When multiple wells in the metering (valve group) room need to measure production, due to the limitation of the low fluid output of a single well, usually only one well can be completed to measure oil production per day, and the oil measurement of all oil wells in the metering (valve group) room can be completed Production measurement usually takes about half a month, and it is only one production measurement for each oil well. Therefore, the real-time performance of the oil (liquid) production data of a single well is very poor, and it is impossible to provide effective data support for the production system
