长岭气田登娄库组成岩作用特征及次生孔隙发育研究

长岭气田位于松辽盆地南部，登娄库组砂岩储层是其主要含气层位。储层的埋深大，成岩作用强，对孔隙发育及孔隙结构影响显著，次生孔隙的发育是登娄库组储层天然气聚集的主要控制因素。研究主要利用薄片鉴定等分析化验数据对登娄库组砂岩储层的成岩作用特征和孔隙结构特征进行研究，并指出登娄库组砂岩储层的次生孔隙发育位置，为气田开发指明了方向。

Study on The Diagenesis Characteristic And Secondary Porosity Development of Denglouku Unit In Changling Gas Field

Denglouku unit is the primary formation of Changling Gas Field loacted in the south of Songliao basin.Its deep cover depth and strong lithogeny play an important role in its development of porosity and porosity structure.It's believed that well developped secondary porosity is the key factor which ever controlled the accumulation of natural gas.Laboratory tests and Analysis,such as thin section analysis,were applied in the research to find out the characteristic of diagenesis and porous structure.Based on t...
