摘要
Carbonate rock facies model of the upper third member of Shahejie Formation of central uplift belt in Dawangzhuang oilfield of Raoyang Depression was studied by core observation, granularity analysis and well log analysis. It can be seen that the aim stratum in the study area develops carbonate rock shoal, and the type of carbonate rock consists of algal-sand-clastic dolomite, oolitic dolomite, micritic dolomite, clastic-bearing sand clastic-oolitic dolomite. Carbonate shoal develops four microfacies: algal shoal, oolitic shoal, micritic carbonate bend and terrestrial grain shoal. The alternation of lake level, ancient landform, the strength of tectonic action and the provision of terrestrial material affect the carbonate shoal, and the change of micro-milieu in the central uplift belt palaeogeomorphology directly affect the rock type and sedimentary microfacies, high terrain develops algal shoal and oolitic shoal, micritic carbonate bend appears in low terrain with low energy. Algal shoal and oolitic shoal are the best reservoirs in the studied area.
