摘要
Using the data of cores, well logging interpretations, seismic sections and experimental geochemistry, this paper analyzes the sedimentary environment,genesis, and distribution of dolomites, as well as the hydrocarbon enrichment factors of dolomite reservoirs in the Permian Fengcheng Formation. According to attitude and structure,the dolomites of the Fengcheng Formation are divided into lamina dolomites,thin-bed dolomites, and spotted dolomites. The factors controlling hydrocarbon enrichment are fractures and structural background.
