摘　　要：针对塔河油田奥陶系断溶体油藏精细刻画困难的问题,利用纵向分辨率较高的测井资料,结合地质和开发等资料,开展断溶体储集空间的分类与识别、断溶体发育影响因素分析,提出塔河油田典型断溶体的发育模式。结果表明:塔河油田奥陶系断溶体油藏的储集空间可划分为裂缝型、裂缝-溶孔型、溶孔型、溶洞型4大类;断溶体的发育程度受地层与断层之间距离的影响最大,受地层抬升剥蚀程度以及泥质含量的影响其次,不同影响因素交织在一起导致断溶体在纵横向的分布和连通方式各异。根据主控因素及纵横向的分布和连通方式的差异,塔河油田奥陶系断溶体的发育可分为V字型、倒V字型、条带型和复合型4种模式。In order to solve the problem of fine description of Ordovician fault-affected karst reservoirs in Tahe oilfield,the reservoir space of fault-affected karst system was classified and identified by using logging data with high vertical resolution and geological and development data,and the factors of influencing the development of the fault-affected karst system are analyzed,and the development modes of typical fault-affected karst systems in Tahe oilfield are proposed.The results show that the reservoir space of Ordovician fault-affected karst system reservoir in Tahe oilfield can be divided into four types:fracture space,fracture-solution pore space,solution pore space and cave space;According to the difference in main controlling factors and vertical and horizontal distribution and connectivity,the development modes of Ordovician fault-affected karst systems in Tahe oilfield can be classfied into V-shaped,inverted V-shaped,strip-type and composite-type modes.
