DEVELOPMENT TREND AND POROUS TEXTURE CHARACTERIZATION OF TIGHT RESERVOIRS IN CHINA

摘要

Tight reservoir is characterized by small pore throat size, complex pore structure, strong heterogeneity and large difficulty in characterization. Through systematically summarizing the development situation of current characterization technology of Tight reservoir, some notable problems in the characterization of pore structure of tight reservoir were pointed out. This paper provides a comprehensive literature review on the simulation techniques being developed in recent years for describing unique flow behaviors in tight gas reservoirs. The future development of pore structure characterization technologies of tight reservoir was put forward.
