RESEARCH ON INDICATORS OF OIL-SOURCE CORRELATION IN THE SUBEI BASIN

摘要: 苏北盆地有上白垩统泰州组二段、古新统阜宁组二段、四段3套油源,母岩干酪根性质和地质环境十分接近,通过一般的地球化学指标很难彻底区分它们,为此因地制宜采用了多参数联合图版以及正烷烃分布、原生甾烷分布、三芳甾系列、二甲基咔唑系列等指标,使3套油源达到有效区分。值得提出的是,用于运移研究的二甲基咔唑系列分布在同源油之间也表现出惊人的稳定性,并且提供出进一步细分油源的指纹信息。Abstract: There are three sets of oil source rock in the Subei Basin.They are the Second Member of Taizhou Formation in the Upper Cretaceous,the Second Member and the Fourth Member of Funing Formation in the Paleocene.Their kerogen properties and geological environments are similar.They are difficult to be distinguished by using common indexes.For this reason,a multi-parameter plate and such indicators as normal alkane,primary sterane,triaromatic steroid series and dimethyl carbazole series have been suggested and triumphantly used for source-rock identification in the Subei Basin.It is recommendable that the dimethyl carbazole series being used for oil-gas migration researches show the amazing stability in discrimination of the oils with the same sources.This provides a detail fingerprint information on the further division of oil origins.
