Design of pressure and temperature monitoring system of coalbed methane well

  • In order to solve problems of existing pressure and temperature data collecting modes of coalbed methane well such as information island caused by manual collection, inability to collect data consecutively, water leakage of pressure sensor and temperature sensor and so on, a pressure and temperature monitoring system of coalbed methane well was proposed. System structure was given as well as compositions of hardware and software. Design scheme of a new type of sensor was focused on, which adopted MEMS technology, vacuum encapsulation and resistive load modulation mode to send collected data. Testing and trail running results show that the system has better reliability, real-time performance and operability, which can reduce field personnel and accidents effectively.
