Abstract

To a certain extent, the development of sand body in lishui depression determines the success of oil and gas exploration, so the development models of sand body become the focus of current research. Based on seismic interpretation and exploration practice, five types of sand body development model were developed in lishui depression, including gentle slope-valley typed sand control model, steep slope-valley typed sand control model, trough fault controlling axial typed sand control model, gentle slope -contemporaneous fault typed sand control model and bulge steep slope-cross section typed sand control model.

Different sand body development model determines the development characteristics of sand body and indicates the direction of exploration.
