摘　　要： 为了进一步弄清虎林盆地生排烃过程,指导下一步油气勘探。基于前人对虎林盆地研究基础上,综合利用了地质、地球物理、地球化学等方法及油气盆地数值模拟技术恢复了虎林盆地成藏动力学过程。结果表明:在虎三段沉积时期,研究区主力烃源岩大部分在达到半成熟,有的甚至成熟,油气开始初次运移,在虎三段沉积后的一次构造中开始发生二次运移。因为盆地此时构造最终定型,油气聚集,形成稳定的油气藏,直至现今。 To further understand the process of hydrocarbon generation and the expulsion in Hulin basin to guide the next hydrocarbon exploration,the author,on a revious study of Hulin Basin,makes full use of comprehensive methods to study geology,including geophysics,geochemistry and basin numerical modeling to restore the process of hydrocarbon accumulation in Hulin basin. The results show that,during the deposition period of Hu Sanduan formation,most of the main source rocks in the area are semi-mature. Some are even mature,and the primary migration of oil and gas will begin with the secondary migration occurred in a tectonic phase after Hu Sanduan formation sedimentary deposits. Because the basin is at this time to be constructed in final shape,hydrocarbon accumulation keeps its formation of stable reservoirs until now.
