摘要
页岩气测井评价的一项重要内容就是确定储层中的有机碳含量。为了能够较简便、准确地估算页岩气储层中有机碳含量,基于常规测井资料,通过ΔLogR法估算页岩储层有机碳含量实验,提出了求取有机碳含量的"RDT-TOC"直接关联法、"RTOC-DTTOC"法和适应中扬子地区海相页岩低阻储层的岩性密度法模型,并通过实例进行了验证分析。
Estimation of organic carbon content of reservoir is a major task in shale gas logging assessment. On the basis of conventional logging data and experiment on estimating organic carbon content of shale reservoir by ΔLogR, this paper discusses ＂R-DT-TOC＂ directed association method for acquiring organic carbon content, ＂Raxc- DTTOC＂ method and lithology density model fit for central Yangtze area with the characteristic of marine facies shale where low resistivity reservoir forms, and verifies them in practice.
