Refined control of gas extraction drilling based on data driven

In order to solve the problems of low gas extraction efficiency and gas dynamic disaster caused by low accuracy of gas reserves evaluation, unreasonable design of drillings and inadequate supervision during drilling construction, a new refined control mode of gas extraction drilling based on data driven was proposed. Firstly, the accurate evaluation of gas reserves and differential design of drainage boreholes laied the foundation for accurate gas drainage; secondly, drilling trajectory measurement and drilling video monitoring were adopted to realize the accurate construction of extraction drilling; then, the high-precision flow sensor and gas drainage pipeline parameter tester were used to realize the accurate monitoring of extraction borehole and extraction pipe network, and the quality of gas extraction data was further improved by establishing the extraction data correction model and borehole failure identification modle; finally, based on the gas drainage control platform, the information-based intensive control of the whole cycle of gas extraction was realized. This new control mode of "process + management" of gas extraction borehole can realize the refined control of the whole cycle of gas extraction borehole design, construction, measurement and management, significantly improve the scientific nature of process control of gas extraction drilling, and also provide a new idea for efficient and intelligent gas extraction.
