该课题以大庆油田萨中开发区 92口资料井和密闭取心检查井的岩心资料为基础 ,试油资料作验证 ,应用孔隙体积权衡和二次函数的曲线回归等方法 ,研究和确定了不同砂体、不同厚度类型的有效孔隙度和原始含油饱和度 ,并进行了合理的误差校正 ,满足了现阶段细分沉积单元地质储量计算 Based on the core data of 92 data wells and closed coring wells in Sazhong Development Zone of Daqing Oilfield, the test data were used for verification. The pore volume and trade-offs of quadratic functions and curve regression were used to study and determine the differences Sand body, effective porosity and original oil saturation of different thickness types, and has carried on the reasonable error correction, has satisfied the present stage division sedimentary unit geological reserve computation
