Abstract

The combination of directional drilling and hydraulic fracturing for coalbed methane extraction has played an important role in gas management in low-permeability coal seams both domestically and internationally. Whether the drilling can meet the design requirements directly affects the extraction effect. This article introduces the system composition and construction method of a memory-type gamma logging tool with drilling trajectory measurement and lithology identification functions, and conducts on-site experiments on gas extraction holes in the Sangshuping No. 2 well. The experimental results show that the instrument works stably, the trajectory measurement and lithology identification are accurate, the working time can meet the needs of directional long drilling, the data obtained by the instrument can verify the drilling trajectory, and the detected lithology can provide guidance for directional long drilling gas extraction, improve extraction efficiency and reduce construction costs.
