吐鲁番—哈密盆地侏罗系成岩作用研究

STUDY OF DIAGENESIS OF JURASSIC SYSTEMIN TURPAN-HAMI BASIN

吐—哈盆地侏罗系为一套陆源碎屑岩地层,经历了复杂的成岩作用,从根本上改变了原始岩石的结构特征,并对储层特性产生了巨大影响。根据成岩作用现象及划分标志,本区侏罗系地层可划归于埋藏成岩阶段的早成岩B亚期,晚成岩A亚期及表生成岩期。

Jurassic system consists of a series of terrigenous clastic rocks wholly in Turpan-Hami basin. The complicated diagenesis has entirely changed the original texture of the rocks, and greatly affected the characteristics of reservoirs. It is evidently concluded that Jurassic rocks in this area have undergone burial diagenesis, and can be classified as B sub-period of eogenetic, A sub-period of telogenetic and epidiagentic stages.
