摘要
通过岩心观察、薄片鉴定、物性分析、测井资料分析等技术手段,研究了济阳坳陷凤山组、冶里—亮甲山组白云岩储层的岩石学特征、成因机制、储集空间特点和储层形成机制。研究结果表明,该套白云岩的形成主要受回流渗透白云岩化作用的影响,可分为晶粒较粗的白云岩、晶粒较细的白云岩和含白云石的石灰岩3类;该套储层主要为一套裂缝—孔隙型储层,储层的形成主要受重结晶、构造与溶蚀等作用的影响,受成岩作用的影响普遍发育了原生晶间孔隙,但后期构造作用是形成有效储层的关键因素,溶蚀作用有效地提高了储集性能,只有在构造作用与溶蚀作用较强的地区才能发育有效的储层。
With the analysis of core observation,thin section identification,physical property determination lithology characteristics and well logging information,the origin mechanism,characteristics of reservoir spaces,and forming mechanism of dolomite of Fengshan and Yeli-Liangjiashan Formation in Jiyang Depression are researched.The result shows that the dolomite formed by dolomiti-zation and refluence infiltration circumstance.There are three types as coarse grain dolomite,fine grain dolomite and dolomitic limestone.The reservoir is the type of fracture porosity,which is formed by re-crystallizing,tectonic action,denudation and some other actions.Because of the influence of diagenesis,it developed widespread intercrystal pores,but the later tectonic action is the key factor of effective reservoir forming,and denudation raised to gather effectively.Effective reservoirs may develop in the area where tectonic action and denudation happened strongly.
