摘　　要：渤海H油田目的层古近系沙河街组沙二段地层中主要含有3种岩性,用常规测井解释模型难以得到准确的地层物性参数和岩性剖面。采用最优化解释原理,在利用交会图技术识别岩性的基础上,建立多矿物模型对H油田沙二段进行处理。将计算结果与岩心分析、X衍射结果进行对比,验证了该模型用于评价复杂岩性储层的可靠性。There are mainly three kinds of lithology in the target layer of Shahejie Formation of Paleogene in Bohai H Oilfield,and it is difficult to obtain accurate formation physical parameters and lithologic profile with conventional logging interpretation model.Based on the principle of optimal interpretation and the identification of lithology by cross plot,a multi mineral model is established to deal with the second member of Shahejie Formation in H Oilfield.Comparing the calculation results with core analysis and X-ray diffraction results,it can be seen that the model can better solve the evaluation problem of complex lithologic reservoirs.
