Wireless monitor and control method of oil well layered segment production parameters

Abstract

The invention discloses a wireless monitor and control method of oil well layered segment production parameters. The production, wireless monitor and control of an oil well intelligent balanced layered segment can be achieved, the real-time transmission and dynamic control of oil well production data can be achieved, and an effective intelligent monitor and control mode is provided for oil well balanced layered segment production. The method includes the steps of making borehole intelligent balanced production control valves connected into a layered segment production string and corresponding to an oil layer, and releasing the layered segment production string in a well through a releasing tool, wherein the valves can achieve automatic intelligent control periodically according to pre-settings; when borehole parameters of the valves need to be manually interfered with and controlled or the valves need to be charged, putting down a bidirectional wireless recognizing control device through a cable, wirelessly uploading the monitor parameters of all the valves to a ground device, wirelessly transmitting redeployed production parameters and deploy instructions to the valves, and conducting wireless recognizing and electromagnetic induction charging on the valves.

Description

technical field [0001] The present invention relates to the production and exploitation method of oil and gas fields, especially the wireless monitoring and control method of the production parameters of oil well layered sections, which can enable the oil well to intelligently balance the layered section mining, wireless monitoring and control, and can realize real-time transmission and dynamic control of oil well production data , to provide effective and intelligent monitoring and control methods for oil well balanced layered section exploitation. Background technique [0002] In recent years, due to years of oilfield development, the comprehensive water content of formations has increased year by year, the oil-water relationship has become more complex, interlayer interference is serious, interlayer production is unbalanced, and heterogeneity is serious, resulting in coning or ridges of bottom water and gas caps. This will cause the wellbore to see water and gas premature...

Problems solved by technology

At present, the monitoring and regulation of downhole parameters at home and abroad mainly use the cable to connect with the downhole parameter control valve to connect the tubing string and pump down into the well, and connect to the wellhead, and collect the production parameters of oil and gas layers through the connection between the ground control system and the cable , storage, regulation, the downhole parameter control valve has no data processor, automatic adjustment, data storage and other functions, this method has the problems of complex construction, long cycle and high cost, and friction and collision between the cable and the oil well casing often occur The cable breaks and the control fails. Therefore, the monitoring and control of downhole dynamic production data is the bottleneck problem in the current oil well production.
