Study of Controll over Karstification of Buried Carbonate Hill Reservoir in Renqiu Oilfield

Based on boreholes and dynamic development data, the control over karstification of buried carbonate hill reservoir in Renqiu oil field was studied. The result shows that 1) Karstific caves, fissures, and pores in dolomite of Wumishan Formation are the most important reservoir voids, 2) the barrier of argillaceous dolomite can result in the existence of residual oil areas under oil-water interface, and 3) the mosores located on the surface of buried hill are also potential areas of residual oil.
