摘要
苏北盆地洪泽凹陷管镇次凹与顺河次凹阜宁组低熟油烃源岩（Ｒｏ＜０．７％）生油史与排油史模拟结果的对比表明，低熟油烃源岩相对于成熟烃源岩通常较难达到含油饱和度排油门限，但是只要低熟油烃源岩区断层发育，在断层作用下石油的初次运移可以发生，并形成工业性油藏。就石油初次运移机理而言，达到排油饱和度门限并不是必要条件，断层可以导致烃源岩在生油主带阶段之前的低熟阶段形成低熟油藏。
It is suggested that faulting is a key to expel low mature oil based on comparisons of oil generation and expulsion history modelling of low mature Funing Formation (Paleocene) source rocks between two subdepressions of Guanzhen and Shunhe in Hongze depression, Subei basin It is indicated that low mature source rocks hardly reached the oil saturation threshold(OST), but faults could make oil primary migration of such source rocks occured It is concluded that before reaching OST,low mature source rocks could expel oil when disruptiny by faults.
