本文根据铸体薄片和扫描电镜观察分析资料,研究了吐鲁番—哈密盆地北部中上侏罗统储集层裂缝的特征,认为裂缝形成于4个期次,分为5种基本类型。裂缝是改善储集层物性的主要因素之一。

The paper approaches the fracture characters of middle-upper Jurassic reservoirs in northern Turpan-Hami basin,based on the analyses of the data from cast thin sections and scanning electron microscopicobservations,It is considered that the fractures were formed in four different stages(times),and basicallycan be classified into five types.Fracture is one of essential factors that would improve reservoir properties.
