摘要

在哈得逊及其相邻地区存在一系列化学组成较为相似的海相成熟原油。具有时代意义的生物标志物的油源对比结果表明,这些原油具有同源特点。通过定性和定量研究,发现这些原油中的萜类化合物的浓度和相对组成的差异在较大程度上与原油的成熟度有关。通过对这些原油中萜类化合物分布特征的研究,可为塔里木盆地成熟海相原油的油源研究提供一些重要的借鉴。认为在用C15-8β(H)-补身烷与C16-8β(H)-升补身烷的比值、三环萜烷与藿烷的比值等参数进行油源研究时,哈得4油田及其相邻地区原油中萜类化合物的这种分布现象应予以充分注意。

Abstract

A series of black marine oils with similar chemical compos ition distributed in Hade 4 Oilfield and correlative areas, which are derived fr om the similar source rocks showed by oil source correlation studies based on ag e-specific biomarkers. By the studies of qualitative and quantitative analysis,  it can be shown that the concentration and internal composition of terpenoids,  such as drimanes, tricyclicterpanes and hopanes, to some extent, are related to  oil maturity. In this point, the characteristics of terpanes occurence can be us ed as a reference for the oil source correlation studies of mature marine oils.  When ratios of C15-8β(H)-drimane to C16-8β(H)- and ratios of t ricyclicterpanes to hopanes are used for the purpose of oil source correlation s tudy, great attention should be paid to the phenomenon characterized by occurren ce of terpanes in Hade 4 Oilfield and correlative areas.
