摘要
通过岩心描述和三维有限元数值模拟，对静北潜山油藏裂缝的分布特征和发育规律进行了研究。该潜山主要发育北东、北西向系统裂缝和呈网状分布的非系统裂缝。前者是区内油气的主要渗流通道，具有与正断层相一致的分布样式；后者是主要的储集空间。裂缝的平均分数维D值1.44，连通性好，夹层中裂缝也较发育，该油藏整体上表现为块状特征。裂缝发育带呈北西西向展布，其发育程度受岩性、层厚和断层等因素控制。
Depending on the core description and three-dimensional finite-element numerical simulation, the distribution characteristic and development of fissures have been studied in the paper. There are NE and NW systematic fissures and network fissures in the reservoir. The former is mainly seepage pathway similar to normal fault, and the latter is mainly storage space. The average fractal dimensional of fissures is 1.44. Fissures link up each other and develop well in interbeds. The reservoir shows blocky characteristic. Fissure zones distribute in WNW-ESE direction and are affected by fault, lithology and bed-thickness.
