摘　　要：准噶尔盆地是我国大型的含油盆地之一 ,盆地的西北缘为著名的克拉玛依油田 .在其外围的玛湖地区进行地表油气化探工作 ,选择酸解烃、ΔC、热释汞等地球化学指标 ,并从已知的玛湖油田地球化学剖面研究入手 ,通过对原油特征、甲烷同位素及未见油气钻井岩芯的地球化学特征研究 ,建立了该地区油气化探异常模式 .酸解烃、ΔC、热释汞等均为“晕圈效应” ,从油气藏中心向两侧 ,直接指标 (酸解烃 )与间接指标 (ΔC、热释汞 )有一定的分带性 ,原油与同位素特征表明已知区和未知区有一定的可比性 .Junggar basin is one of the largest oiliness in China. Karamay oil field is located in the basin. In Mahu area, we select acid hydrocarbon,ΔC,Hg etc. First, we researched on the known oil field and the character of base oil, firedamp isotope, wells with no oil, and the geochemistry character of the known section. We have set up oil and gas geochemistry pattern which is the centre of acid hydrocarbon, ΔC,Hg. Also, from the center to both sides, both the direct and indirect index take on zone. Meanwhile, because of the pattern of base oil and isotope, we have compared the known and the unknown sections. The application of the pattern shows that the method is obviously effective in oil exploration.
