South Yanchuan block has rich geological reserves with great development potential. According to the characteristics, in-door tests and numerical simulation methods, optimization of fracturing parameters such as fracture parameters, construction materi-als, construction scale and construction strings is carried out, and the suitable fracturing technology series of CBM in South Yanch-uan block are formed up. Field application shows that during 1~2 years’drainage after fracturing, production increasing effect is obvious, therefore, the overall development level of South Yanchuan block is promoted effectively.
