摘要： 应用成藏门限理论对塔里木盆地满加尔凹陷周缘4个成藏体系内成藏过程进行了定量评价。结果表明,塔北成藏体系和塔中成藏体系特征具有相似性,而孔雀河斜坡成藏体系和塔东成藏体系具有相似性。4个成藏体系相同的成藏特征是:油气只有满足了烃源岩残留的需要后才能排出,而排出的烃有很大部分在成藏过程中损失掉,只有经过各种损失后剩余的烃才对成藏有意义;越早排出的烃越容易散失,而越晚排出的烃对成藏越有意义;构造破坏和储集层滞留是油在成藏过程中损失的最主要原因,对天然气而言,除上述两个原因外还包括运移流散。

Abstract: On the basis of studying thoroughly their geological conditions, this paper evaluates quantitatively the accumulation of four petroleum accumulation systems around Manjiaer sag in Tarim basin. The study shows that Tabei system is as similar as Tazhong system, while Kongquehe slope system is as similar as Tadong system in features. It is also observed that these four petroleum accumulation systems have such common characteristics as that hydrocarbons could not be expelled until they filled into source rocks completely, and the hydrocarbons drained could be mostly lost in the process of petroleum accumulations, hence only surplus hydrocarbons in excess of lost part is available for accumulation; the hydrocarbons expelled earlier is less favorable for accumulation than those expelled later; structural destruction and remained reservoir rocks are the most important reasons for hydrocarbons lost in the process of petroleum accumulations,for natural gas,migration and dispersion could be added as the other two reasons.

Key words: Tarim basin, Manjiaer sag, petroleum accumulation system, quantitative evaluation, reservoir feature
