摘　　要：顺北4号走滑断裂带断控储集体类型多样,各储集层空间位置,影响储集体连通能力,制约不同部位油井产量。通过探讨一种在钻前评价目标储集体连通能力的方法,对顺北4号走滑断裂带中段断控储集体连通性展开评价。结果表明,顺北4号走滑断裂带中段断控储集体共划分为4个分隔单元,各分隔单元内部洞穴连通率均超过50%,高角度裂缝延伸,垂向洞穴累计厚度大,连通能力较强,分隔单元3与分隔单元4内部的有利目标获取高产概率较大。There are various types of reservoirs in the fault-controlled reservoir system in the Shunbei No.4 strike-slip fault zone,and the spatial positions of the reservoirs affect the connectivity of the reservoir system and restrict the production of oil wells in different locations.A method of pre-drilling evaluation on the connectivity of target reservoir system was proposed to evaluate the connectivity of fault-con-trolled reservoir system in the middle section of the Shunbei No.4 strike-slip fault zone.The results show that the fault-controlled reservoir system in the middle Shunbei No.4 strike-slip fault zone can be divided into 4 compartmental units.The connectivity rates of internal cav-erns of the 4 compartmental units all exceed 50%,with extended high-angle fractures,large cumulative thickness of vertical caves,and strong connectivity.The favorable reservoirs in compartmental units 3 and 4 indicate high probabilities in obtaining higher production.
