摘要

运用族组分、色谱、色谱-质谱等地化测试手段,总结了文昌13-1/2油田原油物性、母质类型及成熟度等地化特征,并分析了原油的来源。认为文昌13-1/2油田原油为典型的低硫、中高蜡陆相油源特征的正常成熟原油,推断原油主要来自文昌B凹陷文昌组滨浅湖相烃源岩。

Abstract

By using group analysis, chromatography, chromatography-mass spectrometry and other means of testing and research, the geochemical characteristics of Wenchang 13-1/2 oilfields such as crude oil proper ties, parent material types and maturity are summarized, and crude oil sources are analysed.The crude oil of Wenchang 13-1/2 oilfields are typical terrestrial source rock with the characteristics of low sulfur, high wax, and normal maturity, which are inferred mainly come from shallow lacustrine source rocks of Wenchang Group in Wenchang B depression.
