摘　　要：CA油田韦5断块属中低渗、多层、砂泥薄互层的稠油砂岩油藏,该油藏采油速度低,开采难度大。在室内微观驱油机理研究的基础上,运用数值模拟技术,对常规开采、热力开采与其他开采方式进行了优选,结合蒸汽吞吐、水力压裂、改性水驱等矿场开发先导性试验成果,确定了韦5断块最佳开发方式。Fault Block Wei 5 in CA Oilfield belongs to viscous sandstone reservoirs with mid-low permeability , multilayer, sandstone thin interbedding, production speed is low in the reservoir and it is difficult in production. On the basis of lab micro-displacement mechanism study, numerical simulation technique is used to optimize the producing modes of conventional production,thermal production and the other production ways. In combination with field pilot testing results of steam soak, hydraulic fracturing, variant waterflooding,the optimal development mode of Fault Block Wei 5 is determined.
