Аннотация
In this paper, we propose a method for multi-vertical well synchronous hydraulic fracturing and compare with synchronous fracturing technologies used in shale. Based on theoretical analysis and triaxial fracturing experiments, we have shown that “face interference” in multi-vertical well synchronous fracturing helps to connect the cleats and generate complex fracture networks. The developed three-step method for designing synchronous fracturing technology was tested under field conditions. The results showed that application of synchronous fracturing decreases the gas breakthrough time in the wells and increases DCBM (deep coalbed methane) production. Furthermore, stress interference generated by synchronous fracturing has a positive impact on the production rate of wells adjacent to the experimental area.
