以M油田为例研究原油地球化学特征

Geochemical Characteristics of Crude Oil:a Case Study of M Oilfield

分析了M油田的S、C、X和Q等油区的一些原油样品,主要分析了其地球化学特征,如原油链烷烃分布特征、萜类化合物、甾烷的分布特征、原油类型的划分等,对不同油区的原油分子组成、化合物的非均质以及这些化合物与原油成因类型之间的关系进行了深入分析,同时还探讨了不同成因的原油在油藏空间上的分布规律,对于揭示M油田的油气富集特征具有一定的参考意义。

This paper analyses some crude oil samples from S,C,X and Q oil fields in M oilfield,and mainly analyses their geochemical characteristics,such as distribution characteristics of alkanes,terpenoids,steroids,classification of crude oil types,molecular composition of crude oil in different oil areas,heterogeneity of compounds and these combinations.The relationship between matter and genetic types of crude oil is analyzed in depth,and the distribution of crude oil with different genetic types in reservoir space is also discussed,which has a certain reference significance for revealing the characteristics of oil and gas enrichment in M oilfield.
