Description
一种新型缝洞型碳酸盐岩油藏驱替模拟实验装置
技术领域
[0001]本实用新型涉及模拟实验技术领域，具体为一种新型缝洞型碳酸盐岩油藏驱替模 拟实验装置。
背景技术
[0002]缝洞型碳酸盐岩油藏储层属于改造型的储层，由于岩性、构造及溶蚀作用等的影 响，其储集空间的类型与碎屑岩储层相比有明显不同，洞、孔、缝为主要的储集空间与流动 通道，且缝洞储集体具有空间随机分布、配置关系复杂、形状尺度变化多样等特点，溶洞是 指直径大于50mm的孔洞，溶孔主要指直径在2m至50m之间的孔洞，裂缝主要以构造、溶蚀缝 为主，裂缝开度大多小于1mm，按照储集空间不同的组合方式，塔河油田奥陶系的三种典型 储层类型为:裂缝型、裂缝一孔洞型、溶洞型，其中，溶洞型储层是以大型溶洞发育为主;裂 缝型储层以裂缝发育为主，洞、孔发育较少;而裂缝一孔洞型储层则是以裂缝和溶蚀孔洞发 育为主，大型溶洞发育较少，溶洞型储层是本区奥陶系碳酸盐岩中最重要的储层类型，其以 大型溶洞发育为特征，是非常好的油气储集空间，溶洞与裂缝为主要的流动通道，据塔河油 田统计，塔河油田溶洞的充填物通常有三种类型，搬运型沉积物、垮塌型堆积物以及化学型 胶结物，前人研宄通常将溶洞分为全充填、半充填和未充填3种，其中塔河些区溶洞充填识 别结果显示:全部充填的溶洞占总数的43%，部分充填的溶洞占37%，基本未充填的溶洞占 到了20%，其溶洞内部充填特征具有重要的生产意义，目前，市场上还没有一种关于缝洞型 碳酸盐岩油藏驱替模拟实验装置。
