摘要
根据岩心、电测曲线、录井、分析化验等资料,研究长岭凹陷大情字井油田青山口组沉积微相类型、沉积特征及其沉积微相的分布规律。利用测井曲线的幅度、形态、接触关系和次级形态4个要素,建立适合本区的青山口组三角洲环境的各种沉积微相解释的测井相模式,为各小层平面沉积微相和砂体分布研究及储层非均质性研究奠定了基础。
Based on core description, electric log, mud logging sedimentary microfacies of According to delta growing Qingshankou Formation, Changling , cores analysis data, the type and characteristics of Depression, and their distribution rule are studied. ＇ s geology, sedimentation characteristics, surface distribution and vertical evolvement in the region, the sedimentary model of delta environment of Qingshankou Formation is built. The electrofacies models that fit to interpret the various depositional microfacies on delta sedimentary environment in Qingshankou Forma- tion, are constructed by using electric log＇ s four factors. They are amplitude , shape, contact relationship and proxi- mate grade providing the base for the study of the plane depositional microfacies and the sand body distribution on each single layer as well as the reservoir heterogeneity.
