摘要:

通过岩芯描述和岩芯样品的常规薄片、铸体薄片、扫描电镜、粘土矿物X-衍射分析及铸体薄片图像分析,王官屯油田孔店组一段枣Ⅱ,Ⅲ油组砂岩储层按砂质河道砂坝砾质河道漫流泥石流沉积的次序物性依次变差。依据孔喉类型与岩石组构间的关系可建立六种相应的储层孔隙结构模式,Ⅰ,Ⅱ类储层以颗粒支撑原生粒间孔和胶结物溶蚀孔隙型结构模式为主,Ⅲ类储层以溶孔-微孔复合型结构为主,Ⅳ类储层以填隙物微孔型结构模式为主。

Abstract:

According to the description of cores,conventional thin sections,injecting thin sections,SEM observation,X-ray analysis of clay minerials and pattern analysis of pore structure,it is found that the heterogeneity and physical property of the sandy river bed,sandbar deposit,conglomeratic river bed,flood plain deposit and debris flow deposit gradully increase and vary worse and wores.Based on the relationship between pore throat types and rock fabric,six types of reservoir pore structure models could be established.The pore structure models of type-Ⅰ and type-Ⅱ reservoirs are mainly primary intergranular pore and solution pore types;that of type-Ⅲ are solution pore micropore types;that of type-Ⅳ is interstitial material micropore type.
