摘　　要：羌塘盆地是油气勘查的复杂区,基岩半裸露和烃源岩出露地表给油气化探带来了新的研究课题。这里针对该区地表地质复杂性特征,对油气化探采样深度、地层对油气化探指标的制约特征和相态烃技术应用效果进行了探讨。研究表明,羌塘盆地油气化探最基本的制约因素是地表出露的地层,以及相态烃技术可以抑制地表烃源岩的干扰。The Qqiangtang Basin is a complicated region for oil & gas exploration. It has been a new subject to geochemical surficial survey for petroleum in the area featuring bedrock partially undefended and hydrocarbon strata outcropped. A research on the complexity of surficial geology, geochemical sampling depth, stratigraphical factors affecting geochemical indices and the effect of pyrolysis-desorbed hydrocarbon technology has been performed in the area. The results show that the essential factor controlling pe...
