Abstract

Abstract: In this paper, both relative permeability model and capillary pressure hysteresis model were established, and the existing black oil model was also improved, which can reflect more accurately the effect of real reservoir capillary force and relative permeability on numerical simulation. Single well Huff-Puff process includes gas injection, shut- in and producing periods.
Based on the improved black oil model, we studied the oil and gas distribution characteristics of each period in the process.The results obtained have important practical meaning for guiding single well Huff-Puff of real horizontal formation.

Key words: relative permeability, capillary pressure, black oil model, hysteresis, numerical simulation, single well
