| 摘 要： | 安棚油田深层系为低孔、特低渗透砂砾岩储层。根据定向取心、成像测井和铸体薄片等资料．对安棚油田深层裂缝的分布特征及其渗流作用进行了分析。该区发育大尺度裂缝、中一小尺度裂缝和微观尺度裂缝3种级次的裂缝类型．以东西向裂缝最发育，其次是北东向和北西向裂缝。但受北东向现今地应力场的影响，该区北东向裂缝的开度大．连通性好，渗透率最高，是该区的主渗透裂缝方向，也是该油田下一步开发井网调整的主要地质依据。

| Abstract: | The deep reservoirs in Anpeng Oilfield belong to low porosity and ultra-low permeability glutenite reservoir. According to the data of orientated coring,imaging logging and cast sections,this paper analyzes the distribution characteristics and seepage flow effects of deep fracture. There are large scale fractures,middle and small scale fractures and microscopic fractures in the study area,with the fractures being the most developed in EW trend and secondly in NE and NW trends. The fractures of NE trend have... |
