| 摘 要： | 在西部复杂叠合盆地中,油气藏形成后的调整改造现象非常普遍.通过对塔中地区调整改造事件的分析,认为塔中地区经历了3～4期调整改造,分别为:奥陶纪、志留纪的破坏性改造、印支-燕山期的调整性改造、喜马拉雅期的建设性改造.在塔中地区的具体表现形式为断层的局部活动和圈闭的局部迁移.调整改造对塔中地区油气藏的影响主要表现在3个方面:(1) 导致了多种相态油气并存;(2) 导致了油气的再分配;(3) 导致了油气藏的现今分布格局.目前塔中地区发现的油气藏大部分是从下伏地层调整上来的次生油气藏,在后期构造调整较弱的塔中10号带、塔中I号坡折带西部地区下伏奥陶系、寒武系有良好的勘探潜力.

| Abstract: | In the complicated superimposed basin in western China,the adjustment and modification after the formation of oil and gas reservoirs are very common,through the analysis of the adjustment and modification happening in central Tarim Basin,it is recognized that the area underwent 3 to 4 times adjustment and modification,they were in Ordovician and Silurian,which was destructive,Indo-Yanshan period and Himalaya period,which were constructive.In central Tarim area,the forms of the adjustment and modification ar... |
