Popis: In order to improve the success rate of oil and gas exploration and further study the impact of tight sandstone cements on reservoirs, this paper uses a large number of rock thin sections, scanning electron microscopy, and physical property analysis to analyze the cements of the Chang 6 reservoir in the Panke area, southern Ordos Basin. Features have been studied in depth. The results show that the cements in the study area mainly include: authigenic cements such as illite and chlorite, carbonate cements such as iron calcite and iron dolomite, and siliceous cements. As the depth of the stratum increases and the temperature rises, the content of illite gradually increases; the main distribution area of chlorite cement is shallower than that of illite; with the increase of buried depth, the content of carbonate cement has a increase trend ; The content of siliceous cement in the deeper stratum is higher than that in the shallow layer.
