摘　　要：三江盆地是一个复杂残留叠合盆地,勘探程度较低。在系统总结已有地质认识和勘探成果的基础上,分析盆地内地层的分布情况和特点,结合盆地构造背景及沉积演化特征,统计分析有机碳、生烃潜量等盆地各项石油地质参数,确定三江盆地烃源岩的生烃特征及潜力。结果表明:三江盆地具有较大的勘探潜力,三江盆地西部绥滨坳陷以穆棱组、城子河组为主要的烃源岩,且进入成熟阶段,发育煤层气,油气勘探应以找气为主,找油为辅;前进坳陷浅层生物气具有较大的勘探潜力。该研究为三江盆地勘探与开发提供了参考。This paper is focused on the study of Sanjiang basin occurring as a complex superimposed basin of low degree of prospecting. The study identifies the characteristics and hydrocarbon generation po- tential of hydrocarbon source rock of Sanjiang basin by the systematic summarization of the existing geo- logical understanding and the exploration results, the analysis of the stratigraphic distribution and charac- teristics, combination of basin tectonic background and depositional evolution characteristics and the sta- tistical analysis of organic carbon, hydrocarbon generating potential and other petroleum geological param- eters of the basin. The results show that the presence of a greater exploration potential in Sanjiang basin is due to the fact that Suibin depression, located in the western region of Sanjiang basin, consists of the main hydrocarbon source rocks dominated by Muling group and Chengzihe group and is at the mature stage for the development of coal-seam gas, requiring that an oil-gas exploration be dominated by gas search; and the shallow biogenic gas of Qianjin depression boasts a greater exploration potential. This study may provide a reference for the exploration and development of Sanjiang basin.
