摘要

对大民屯凹陷高蜡原油和不同性质源岩抽提物的高温气相色谱分析获取了高分子量烃类的组成及分布信息,在C40以上分布范围内除高分子量正构烷烃外还可观察到完整的异构或环烷烃系列,其丰度与分布特点受源岩热演化程度的控制,这些高分子量烃类的检出为解释高蜡油的成因提供了直接证据。

Abstract

By using high temperature GC analysis of high wax oil and rock extracts in Damintun Depression,the distribution and composition of high molecular weight hydrocarbons (HMWHs) were determined.Except for high molecular weight n-alkane,complete isoparaffin or cycloparaffinic hydrocarbons were observed in hydrocarbon of C40 above.Their abundance and distribution are controlled by thermal evolution of source rocks.It proved direct evidence of origin of high wax oil as a result of detection of HMWHs.
