【 摘 要 】

The study of reservoir diagenesis is to reveal the type and characteristics of diagenesis. The general process of reservoir diagenesis research: Firstly, the study of diagenesis products, including systematic observation and analysis of reservoir cores, pays special attention to the changes of reservoir pores in time and space. We can obtain more accurate lithological data, various diagenetic phenomena and pore variation characteristics, and speculate on the diagenesis process that may be experienced. Secondly, according to the diagenetic parameters such as pore fluid temperature and pressure, the diagenesis reaction mechanism is discussed from the perspectives of physical chemistry and thermochemistry. Finally, combined with the stratigraphic, tectonic and sedimentary data of the basin, the reservoir diagenesis model is established to find out the evolution law of the pores.
