摘要
三塘湖盆地主要分布有中、下侏罗统水须沟群，中、上三叠统小泉沟群和二叠系上藉藉槽群3套生油岩。目前已在中侏罗统西山密组砂砾岩及下二叠统卡拉岗组火山岩中发现了油气流或油气显示．本文介绍了三塘湖盆地主要生油岩和二叠系原油的地球化学特征，根据原油和生油岩总体组成和分子地球化学组成特征进行油源对比，分析了二叠系原油的主要来源油源。
There are mainly three sets of source rocks distributed in the Santanghu Basin: the Middle and Lower Jurassic Shuixugou Group, the Middle and Upper Triassic Xiaoquangou Group and the Permian Shangjijicao Group. At present, oil/gas flow or oil/gas showing is discovered in the grit rock of the Middle Jurassic Xishanyao Formation and the volcanic rock of the Lower Permian Kalagang Formation. In this paper, the main source rocks of the Santanghu Basin and the geochemical characteristics of Permian crude oil are introduced. Based on the total composition of crude oil and source rocks and the compositional characteristics of molecular geochemistry, the oil-source rock correlation is conducted and the main source rocks of Permi an crude oil is analysed.
