Geologieal reserves ofoil and natural gas is reserves in the ground, and it is acomprehensive reflection of oil and gas exploration and development. Reserves of oil and gasprovides the important basis for exploration,development and investment scale of oil and gasfield.Xia Siwan oil field is located in east of the Shanbei slope of Eerduos Basin. It’s aconcentration region of Oil and gas in Mesozoics of ordos basin.Chuan Dao area is located inthe south-central in Xia Siwan oilfield. Drilling found the main oil layer section is chang22and the oil layer is focused on chang223, belonging to a small, special low abundance, shallow,light conventional reservoir.In this paper,based on Chuan Dao area of Xia Siwan oilfield,the rearch is guided by thetheory and methodology of petroleum geology, sedimentary, lithofacies paleographic,petrology, geophysics and other subjects and combines previous studies as well as the corematerial, logging data,analysis and test material.Through the geological research of ChuanDao area, we make clear the types of sedimentary facies and exhibition cloth, reservoircharacteristics and its types, oil and gas distribution; this area has high development degreeand the comparatively perfect development well nets,whose geological understanding andreserves rearch degree are all up to demand of calculating proved reserves ofdevelopment;through detailed interpretation of logging data, determine four property relationsof reservoir, effective porosity and oil saturation logging interpretation model and net paycut-off thickness; finally, based on the previous accounts, research reserves parameters andcalculate geological reserves and recovery with the method of volume for Chuan Dao area.The rearch provides the basis for setting reasonable oil field development scheme in ChuanDao area in Xi Siwan oilfield.
