摘要
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。
This paper evaluates the amount of low-maturity oil generation and expulsion in the northern part of the Songliao Basin. The amount of generation is about 20-25 percent of the conventional mature oil amount. Therefore, the low-maturity oil resources volume is predicted to be about 5-10 percent of the mature oil resources volume. Exploration of this non-conventional oil resources should draw adequate attention. While taking into account the plane distribution of hydrocarbon generation and expulsion degree, this paper evaluates the prospect areas for exploration of low-maturity oil in the region
