摘　　要：将有机质成烃的过程分解为有机质生成C14^＋油、C6-C13轻质油及C5^-天然气3组平行过程,进行了求取各组成烃反应化学动力学参数所需的模拟实验,建立并标定了3组化学动力学模型。运用该模型评价了松辽盆地齐家-古龙凹陷3类油气组分的生成量、排出量及凝析油气的资源量。结果表明,区内凝析油的资源量约为（150-870）×10^4m^3,对应的凝析气的量为（750-4350）×10^7m^3,总体资源潜力不大,但轻质油的总资源量可高达22.3×10^8t。The hydrocarbon-generating process of organic matters was decomposed into three groups of parallel processes,including generation processes of C14^＋ oil,C6-C13 light oil and C5^- gas. The simulation experiments to obtain the parameters of chemical kinetics were designed. Three groups of correlative chemical kinetics models were established and calibrated. These models were used to evaluate the generated and expelled hydrocarbon amounts of three groups of components and the resources of condensate oil and gas in Qijia-Gulong Depression of Songliao Basin. The evaluation result indicated that the resource of condensate oil in the depression is about 1.5-8.7 million cubic meters,and the corresponding amount of condensate gas is about 7.5-43.5 billion cubic meters. The overall resource potential of condensate oil in the depression is limited,but the total resource amount of light oil is up to 2.23 billion tons.
