Analysis of the main controlling factors of intra-well frac hit between deep coalbed methane in Daning-Jixian block and research on countermeasures to prevent and control it by Ming CHEN, Junyi SUN, Liwei WANG, Lizhu YU, Haonian TIAN, Dameng WANG, Xianfeng GU, Zesong YIN, Huan ZHANG

“…Then, based on the objective geological conditions of Daning-Jixian block and the understanding of development and production practice, using the multi-factor gray correlation analysis method, we evaluated four categories and nine sub-factors of influencing factors, such as development and deployment (distance between wells, location of horizontal section, vertical depth), geology (strength of natural fracture), engineering (average scale of single-cluster fluid, number of perforation clusters, scale of single-section fluid, and construction displacement), and drainage and extraction (production time of the parent well), the distance between wells, production time of the parent well, average single-cluster fluid size, and natural fracture were identified as the main control factors for the pressure frac hit of deep-seated coalbed methane horizontal wells in Daning-Jixian block, and corresponding preventive countermeasures were developed based on these factors. …”
