摘要
In Turpan-Hami basin,multi-source rocks are developed in Xiaocaohu secondary sag,and show good source conditions,abundant petroleum resources and bright prospects for exploration.Three reservoir-cap assemblages developed in Middle Jurassic formed reservoir types in the sag which are structural-lithology oil-gas pools in Sanjian fang formation and Qiketai formation along with deep basinal gas pools in Xishanyao formation of Jurassic.The late Yanshan movement is a major stage for hydrocarbon accumulation in Xiaocaohu secondary sag.The primary controlled factors for its hydrocarbon accumulation is due to its palaeo-structures,tectonic setting and traps with structural-litholo gy feature.The exploratory efforts has good effectiveness based on these main controlled factors for evaluation and optimization of its favorable zones.
