Embodiment Construction

[0099] The present invention is described in detail below with reference to accompanying drawing and embodiment:

[0100] attached Figure 1-9 It can be seen that a downhole wireless flow control system with wireless duplex communication uses packers to isolate oil layers; a downhole wireless flow control device with wireless duplex communication is installed between adjacent packers. The downhole wireless flow control device of Gongtong realizes remote intelligent remote sensing and remote control through pressure pulse transmission and downhole remote telemetry / remote control system. No physical connections are required, nor are any signal amplifiers and additional wellhead equipment required.

[0101] The downhole wireless flow control system with wireless duplex communication includes: throttling sliding sleeve assembly, downhole microprocessor and measurement controller assembly, wellhead microprocessor and program controller execution unit assembly.

[0102] The thrott...

Abstract

The invention relates to a wireless duplex communication underground wireless flow control system and control method. Oil layers are isolated through packers, a wireless duplex communication underground wireless flow control device is mounted between adjacent packers, the wireless duplex communication underground wireless flow control device achieves remote intelligent remote sensing and remote control with an underground remote metering/remote control system through pressure pulse transmission, according to the wireless duplex communication underground wireless flow control system, a flow control device is used for interfering production or pumping-in flowing through the artificial intelligence manner, a signal based on fluid pressure is transmitted, condition changes related with production or pumping flowing are identified on a wellhead and underground, according to condition changes, a flow control device is operated, through adjusting of the opening degree of a valve in a pipe flow in an underground protection oil pipe, a wireless coding signal is sent in an oil well or gas well, mounting, retrieval and maintaining are easy, and operation risks and production cost are reduced.

Description

technical field [0001] The invention relates to an oil drilling and production downhole tool, in particular to a downhole wireless flow control valve tool with wireless duplex communication and its system. Background technique [0002] To optimize recovery, the petroleum industry relies on data collected from wells and reservoirs. This data forms the basis for nearly all decisions in field development and operations, including the location of new wells, maintenance planning and production allocation / control. Given the need for data, many wells are equipped with permanent downhole instruments such as pressure, flow and temperature monitoring devices. [0003] Due to the generally harsh wellbore environment, permanent instruments have a limited service life and often fail. This failure results in limited information from the reservoir and limited ability to control wellbore fluids. This will seriously affect the understanding and modeling of the reservoir and reduce the rec...
