Method for measuring oil and gas yield of single well in metering room valve group room by adopting robot

Abstract

The invention discloses a system for measuring the oil and gas yield of a single well in a metering room valve group room by adopting a robot. The system comprises a separator body, a magnetic turningplate liquid level meter, a water path pipeline mechanism, an oil path pipeline mechanism and a valve operation device, wherein in the oil path pipeline mechanism, one end of an oil return junction is connected with the separator body through a separator outlet inverted U-shaped pipe, the other end of the oil return junction is connected with an oil storage container, the inverted U-shaped top ofthe separator outlet inverted U-shaped pipe is connected with one end of a gas balance pipeline, and the other end of the gas balance pipeline is connected with the top of the separator body; and oneend of each single well oil supply pipeline is connected with a corresponding well mouth, and the other end of each single well oil supply pipeline is connected with a separator inlet pipeline through a single well separator inlet valve and is connected with the oil return junction through a single well oil return valve. According to the system, the oil measurement and production measurement speed is increased, the original mode that only data of one well can be measured every day is changed into the mode that each single well in a metering room is measured once every day, and the precision and real-time performance of the data are improved.

Description

technical field [0001] The invention belongs to the technical field of oil recovery, and relates to a method for measuring oil and gas production of a single well in a valve group of a metering room using a robot. 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 sink and flow to the combined station; at the same time, the water-mixed pipeline can also switch and conduct the single-well hot-wash valve to introduce the hot-washed high-pressure hot water...

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

[0006] Chinese patent CN102852513B U-shaped tube integrator continuous oil measuring device only provides a metering method, in order to eliminate the influence of valve switching on pipeline pressure, this method needs more than 3-5 continuous oil measuring to obtain Approximately accurate results, so the valve operation in the metering room of the device still needs more manual attention to complete, and at the same time increases the time for measuring oil in a single well, it is difficult to be suitable for oil measuring of multiple wells in the room every day, the practical significance extremely limited
