Formation Of Underground Communication And Ground Monitoring System For Real-time Monitoring Of Test Research

This topic research by the formation testing real-time monitoring of underground communication and ground monitoring and control system,can be convenient and formation testing tools and docking,using a wide,construction is convenient.The set of research equipment adopts the principle of wireless transmission,the downhole electronic counting the way which the wireless real-time transmission to the temperature and pressure testing tool at the top of the receiver,through the cable will bottom hole temperature and pressure data transmitted to the gro und.The subject of the research design tasks including cable communications and ground monitoring inoue part of the circuit and the software design and improvement,etc.Specific research task:Design telemetry module is used to control the downhole data transceiver system to send and receive instruction,through the multi-core cable duplex data communications with the ground;Develop ground telemetry board amplifiers decoding process,such as ground telemetry board monitoring PC real-time interactive communications with the ground;Debug the ground monitoring PC direct reading software testing data detection and real-time instruction issued by function,and software functions of actual debugging repeatedly,so it can accurately recover data to realize downhole pressure and temperature of playback,real-time test data curve drawing shows of stratum logging construction process and monitoring.C ircuit of the system and mechanical equipment of the alignment process,ensure the realization of the basic function circuit,and can adapt to the actual test operation demand of oil and gas Wells.
