本文对松辽盆地北部未熟—低熟石油的生成量、排出量进行的定量评价表明,其生成量约为常规成熟油的20％～25％;在此基础上预测的未熟—低熟油的资源量约为成熟油资源量的5％～10％。因此,对这一非常规石油资源的勘探不应忽视。同时结合生、排烃强度的平面分布,评价了区内未熟—低熟油勘探的有利区域。
In this paper, the quantitative evaluation of the generation and emission of under-mature and low-mature oil in the northern part of Songliao Basin shows that the production is about 20% ~ 25% of that of conventional mature oil. Based on this, the predicted immature-low mature oil The amount of resources is about 5% ~ 10% of the amount of mature oil resources. Therefore, exploration of this unconventional oil resource should not be overlooked. At the same time, the favorable distribution of immature and low mature oil in the area was evaluated based on the plane distribution of the hydrocarbon generation and expulsion intensity.
