塔里木盆地北部沙雅隆起三叠—侏罗系储盖组合评价

APPRAISAL ON RESERVIOR-ROOF ASSOCIATION OF TRIASSIC-JURASSIC IN SHAYA UPLIFT OF NORTHERN TARIM BASIN

根据储层与盖层特征及两者的关系 ,对塔北沙雅隆起三叠—侏罗系储盖组合进行评价 ,指出以中三叠统阿克库勒组中部为盖层 ,下段为储层的组合为全区最好的组合。同时探讨了储盖组合与油气运移、聚集的关系 。

Based on characteristics of reserviors and roofs,and relation between them,an appraisal is given of Triassic- Jurassic reservior- roof association in Shaya uplift of the northern Tarim basin.The best assoica- tion in the region is pointed out,i.e.,middle Akkule Formation of Middle Triassic as the roofs and lower member as the reserviors.The relation is also discussed between reservior- roof association and oil- gas migra- tion- accumulation.The Hymalayan stage is believed to be the main pool formation stage of Triassic- Jurassic oil- gas pool.
