Temporal Scale Analysis of Gas Flow in Tight Gas Reservoirs considering the Nonequilibrium Effect

The fractal geometry, anisotropy, discontinuity, and non-Darcy flow of tight reservoirs exert a significant effect on well production performance. In this study, the reservoir geometry is represented by exponential functions basis microseismic data, while discontinuity fractures presented as nonequilibrium effect. impact low velocity temporal scale wellbore pressure predicted herein. Results showed that time analysis accurately simulates gas in reservoir. gradually increases, whereas matrix lags when considered. affected early period However, at later stage, mainly flow. When dominant, pores without flowing through are better presented.
