The new technology of composite perforation, which combines together the conventional perforation and the high energy gas fracturing, can effectively increase the hydrocarbon production and improve the enhancement of the oil/gas recovery. In recent years, the composite perforation technique has been widely used worldwide. However, this technology was not used extensively in Chinese oil filed because its research on the combustion characters of propellant is rare and the corresponding optimal perforation design is not practical. Based on a comprehensive analysis of the propellant’s burning features, we establish a new combustion model for the propellant used in composite perforation, which takes into account that the combustion consists of the cylinder layer burning and circular burning along the perforation tunnels. Using the actual well data from oilfield and the conventional parameters of domestic propellant, we use this new model to perform numerical simulations and analyze in detail the process of related pressure change. The simulation results are accordance with the actual data from field operation, which further confirms the reliability of the model. The established model can provide better references for the optimum design of composite perforation.
