伦坡拉盆地的地质背景较为独特而又复杂.“豆夹形”的走滑盆地构型,断-坳转换过程中体现出的“迟到早退”双层地质结构,发育于盆地内部的变换构造以及后期冲断隆升、逆掩推覆的强烈变盆改造等,形成了两套盆地含油气系统,3个成油单元,多种类型的成藏组合的油气地质特征.通过对以上成油气地质特征的分析认为:(1)上部含油气系统的油气潜力比下部含油气系统要差;(2)生油凹陷主要分布在蒋日阿错次凹和爬错次凹的中南部与北部;(3)油气运移的主要指向和聚集区带位于盆地北部;(4)查清逆掩推覆体下伏的盆地原体和塘奴陇果变换带以及深部地层(牛堡组二段底部和牛堡组一段上部)的含油气性,是今后值得重视的3个勘探领域.
The geological background of the Lunpola Basin is unique and complex. “The” Doujiagou “strike-slip basin configuration and the” late arrivals and departures "double-bedded geological structures that appear during the fault-depression transition are developed in the basin The internal transformation structure and thrusting and uplifting in the later period, and the strong deformation basin transformation in overthrusting and overthrusting etc., formed the petroleum geological features of the two sets of petroleum systems, 3 oil-forming units and various types of hydrocarbon accumulation combinations. The above analysis shows that: (1) The hydrocarbon potential of the upper petroleum system is worse than that of the lower petroleum system; (2) The oil-producing depressions are mainly distributed in the middle of the fault Southern and northern parts of the basin; (3) the main orientation and accumulation zone of hydrocarbon migration are located in the northern part of the basin; (4) the original basin and Tongu Longgu transformation belts underlying the thrusting nappe and the deep formations The bottom of the second member of the group and the upper part of the Niubebao Formation) are the three exploration areas that deserve further attention in the future.
