The invention discloses the efficient detection system.

Description

technical field [0001] The invention relates to the technical field of coalbed methane drilling, in particular to a real-time monitoring system for coalbed methane well sites. Background technique [0002] As an important energy gas, coalbed methane has a wide range of applications and provides an important energy supply for national production. [0003] Process control in the process of coalbed methane drainage has a very important impact on drilling efficiency and safety. Usually, the process operation is performed according to the experience of the drilling personnel; the efficiency is often low, and at the same time, drilling accidents occur due to some invisible factors downhole, which seriously affects production safety and efficiency. At the same time, due to the lack of reliable data, it is very inconvenient to evaluate the production capacity of coalbed methane and formulate the drainage process. On the other hand, due to the impact of drilling operations and the ...
