摘要: 应用岩石溥片、铸体薄片、x衍射和扫描电镜等分析资料,着重探讨吐哈盆地中侏罗统储层成岩作用及其孔隙演化,研究表明:压实作用强烈是造成储层为低孔渗性的基本原因,胶结作用受渗-扩散机理和热驱对流机理控制,并可形成一种成岩圈闭。

Abstract: By an intigration of the data from thin sections, X- diffraction, Scanning Electrical Micro-scope, the author of this paper discussed in detail on the evolution of porosity and diagenesis of Middle Jurassic Reservoir in Tuha Basin, it is indicated that stong compaction is the basic origin of low porosity and low permeabity reservoir. The cementation is controlled by the permeating-diffusing mechanism and the heat convertion mechanism and be able to result in the formation of diagenic trap.

Key words: Reservoir, Diagenesis, Pore evolution, Diagenetic trap
