摘　　要：为了提高伊通盆地梁家构造带双二段有利区域的预测精度,通过综合本区储层岩性、物性、含油气性和电性及其四性关系特征,并结合试油结果,根据岩心分析、录井及试油资料约束测井的方法,建立了本区泥质含量、孔隙度、渗透率和束缚水饱和度模型。将取心井岩心分析数据与模型解释数据进行比较,验证了解释模型的正确性,提高了测井解释的成功率,最终确定岩性、物性、含油气性及电性下限标准,完成了储层参数从取心井到非取心井的最佳定量取值,为有效识别流体性质提供了有利支撑。A suit of interpretation model for shale content,porosity,permeability and irreducible saturation within theworking area was built via the method of restricting logging according to core analysis,logging and oil testing data to improve theaccuracy of predicting the favorable area of E2s2 in Liangjia structural belt area on the basis of comprehensive analysis of lithology,physical property,electrical property,hydrocarbon-bearing property,combined with the result of oil test. The model was verifiedby comparison to core analysis data and interpretation data of the model,which promotes the success of log interpretation. The lowerlimitations of lithology,physical property,oil-bearing property and electrical property are precisely defined,providing a favorablebasis for the effective identification of reservoir fluid properties and realizing the optimal quantification of reservoir parameters fromcoring wells to non-coring wells.
