A measurement and control production pipe string for stratified section mining

Abstract

The invention provides a layered or segmented mining monitoring and control production tubular column used for layered or segmented milling production of an oil well. By means of the layered or segmented mining monitoring and control production tubular column, continuous monitoring and control of layered or segmented mining production are achieved, and a technical means is provided for obtaining dynamic production means of the oil well in real time and regulating the production situation of the oil well in time. The production tubular column is released underground through a release tool, underground testing and regulating devices are connected through an oil pipe cluster below packers and centralizers, and an intelligent real-time regulation and control device is connected between the release tool and the corresponding packer through the oil pipe cluster. The underground testing and regulating devices in the production tubular column are connected in parallel through a connection cable, the connection cable is fixed to the outer portions of the underground testing and regulating devices, the centralizers and the packers through cable protectors, and the upper end of the connection cable is connected with the intelligent real-time regulation and control device. A shell of a radio frequency identification communication module of a two-way wireless regulation and control device is inserted in an inner central pipe of an eccentric installation cavity of the intelligent real-time regulation and control device and controls connection between the cable and a ground control device.

Description

technical field [0001] The invention relates to a layered or segmented production string in the oil industry, in particular to a layered segmented production measurement and control string used in the layered or segmented production of oil wells to realize layered or segmented production Continuous monitoring and control provide technical means for real-time acquisition of oil well dynamic production data and timely adjustment of oil well production. Background technique [0002] With the deepening of oil and gas exploration and development, the quality requirements for the acquisition of oil well dynamic production data are getting higher and higher. At present, there are two technical means for routine production testing at home and abroad. One is the direct-reading cable test on the ground. This test method requires the connection between the cable connector and the downhole connector. However, due to the poor reliability of the wet cable connection, the success rate of ...

Problems solved by technology

One is the direct-reading cable test on the ground. This test method requires the connection between the cable connector and the downhole connector. However, due to the poor reliability of the wet cable connection, the success rate of on-site implementation is not high; the other is the downhole storage test. There is an acquisition unit and data storage in the underground. Although it can be collected and stored for a long time to obtain relatively complete production data such as pressure, temperature, and flow, it lacks the test of key production parameters such as water content.

In addition, its regulation is not real-time, and it is a passive test. If there is a failure underground, the ground cannot be informed
