摘要（英）：

The invention relates to the technical field of coalbed methane equipment and discloses a coalbed methane downhole pressure detection device. The coalbed methane downhole pressure detection device comprises a base, a pressure detection mechanism, a data processing device, a shell, a seal seat, a seal pressing cover and a transmission cable. The pressure detection mechanism is connected with the base and comprises a pressure detection bin, a pressure sensor arranged in the pressure detection bin, and a first bin cover connected with the upper portion of the pressure detection bin. The data processing device is connected with the pressure detection mechanism, comprises a processing bin, a data processing circuit arranged in the processing bin, and a second bin cover connected with the upper portion of the processing bin, and is located on the upper portion of the pressure detection mechanism. Through the coalbed methane downhole pressure detection device, the problems such as poor leakproofness and inaccurate measuring results are solved, real-time detection of pressure is achieved, and the leakproofness and measuring accuracy are improved.
