摘要
济阳凹陷5号桩地区中生界地层,岩性复杂,非均质性强,孔隙结构复杂,测井资料解释难度大。应用测井相分析方法分析岩性与电性之间的响应关系,总结了该区各种岩性的测井响应特征,精确识别了该区15种岩性,并依据测井相分析结果,将岩性划分为不同类型,应用岩心分析资料刻度,划分岩性类型,建立了该区测井储层参数的精细解释模型。与试油资料对比表明,该方法具有良好的应用效果。
Logging interpretation is difficult in Wuhaozhuang area, Jiyang depression because of complex lithology, strong heterogeneity and complex pore structure Based on an analysis of the relationship between lithology and logging responses, we summarized the response characters of different lithology, and classified them into 15 classes. The different classes were then transferred into different types of lithology according to the result of logging face analyses. A logging interpretation model was set up using the scaling of core data and log phase. The model has high accuracy comparing to production test data.
