Reservoir Diagenesis

Abstract

Diagenetic evolution in petroliferous basins is usually one of the main research focus areas in oil and gas exploration. However, clastic reservoir diagenesis is influenced by numerous factors, including mainly basin tectonic evolution, depositional system distribution, burial history, thermal evolution history, and underground water solution activity. As a result, petroleum geologists should consider the structure, deposition, and diagenesis of a basin and take them as an organic whole for the analysis and research of porosity evolution in a certain period or at a certain position. In addition, multi-disciplinary theories and methods should be applied to discuss the law that the hole varies with the evolution of time, space, and position. Similar to the factors influencing reservoir heterogeneity, as mentioned in Chap. 6, the macro factors determining the reservoir pore development law are ① tectonic evolution stage, ② sedimentary pattern complexity, and ③ diagenesis diversity.
