Abstract

Based on the regional geologic background, the rock color and texture, sedimentary structure, sand body distribution and sedimentary sequence combining with logging curves are applied to study the sedimentary microfacies of Chang 213 in Jing’an Oilfield. The result shows that the target stratum in the study area is a suit of braided deltaic plain, consisting of underwater distributary channel, interdistributary bay, natural levee and crevasse splay, and that the underwater distributary channel sand bodies constitute the dominated reservoir, which provides geological foundation for the further exploration and development in the target stratum.
