摘　　要：针对Q29-2油田复杂储层岩性识别和矿物组分的定量计算等测井评价难题,结合岩心及测井资料,提出元素俘获测井(ECS测井)和M-N交会图结合建立关键井岩性剖面技术,在该基础上通过聚类分析方法建立的常规测井响应与岩相的对应关系实现了岩性的定性识别。在岩性定性识别约束下的多矿物测井解释模型,实现了利用常规测井曲线进行复杂岩性段矿物成分的定量计算,解释结果与岩心分析结果符合度高。岩性定性及定量识别技术为储量参数确定及地质研究奠定了基础。In allusion to the problems of complex lithologic identification and the quantitative calculation of mineral composition in logging evaluation,in combination with rock sample and logging data,ECS logging and M-N crossplot were proposed by the combination of the establishment of lithologic section of key wells,on the basis of the study,the technology of clustering analysis was used to establish the correspondent relationship between the conventional logging response and the lithofacies.By using the multi-mineral logging interpreting model constrained by qualitative lithologic logging,the quantitative calculation of mineral composition in the complex lithologic zones was implemented by using the conventional logging curves,the interpreting result was highly consistent with that of core analysis.The technology of lithology identification and quantitative analysis is the basis of the determination of reserves parameters and geological studies.
