In this paper, the characteristics of reservoir of reservoir of delta frontal sub-faces of PI Formation in the south of Xingshugang are studied with the data of dense well pattern and rock-mineral identification. The delta frontal sub-faces can be divided into lobate delta frontal sub-faces, branched delta frontal sub- faces and sheeted delta frontal sub-faces. The genetic types of sand bodies in different sedimentary envivonments are analyzed in detail, and the distribution and space-matching relationship of different sand bodies are studied. The micro-pore structure type is studied on the base of the thin section analysis, so the reservoir heterogeneity is studied including plane heterogeneity, interlayer heterogeneity, in-layer heterogeneity and microcosmic characteristic.
