摘要
Abstract
After the hydraulic fracturing of horizontal wells,shale gas reservoir seepage areas show a complex fracture net-work morphology,single well flow numerical model considering desorption-adsorption mechanism has a strong theoretical value and practical significance for analyzing single well production factors. Based on Warren-Root dual media model guiding ideolo-gy,matrix flow mathematical model and fracture flow mathematical model are established considering desorption-adsorption. Methods of discrete differential equations is designed and IMPES seepage linear processing method is carried out,and finally iterative simulation programming is realized through the Gauss-Seidel. Field applications,based on the results of the micro-seismic for fractured horizontal wells in shale reservoir geological model was constructed,the established numerical model can analyze the impact of pressure,gas adsorption,permeability,formation properties and other characteristics on production parameters. The results are consistent with the law of shale gas production,so this simple model can effectively guide the field of engineering design and dynamic analysis.关键词
