摘　　要：南泥湾油田长4+5、长6储层属于特低渗、低压油藏,压裂是油藏开发最主要的措施。通过在南泥湾油田长4+5、长6储层选取有代表性的20口压裂井进行水力压裂裂缝检测及井下压力-温度检测,确定压裂裂缝的形态、方位、高度、产状及压裂液的滤失系数、液体效率等,为南泥湾油田压裂评价及注水开发工作提供依据,同时也为其它区域的开发井网部署、压裂参数优化、扩边勘探、旧井转注等工作提供依据。The Chang 4 ＋ 5 and Chang 6 reservoir of Nanniwan oilfield belong to the ultra - low permeability and low pressure reservoir, and fracturing is the most important measures for reservoir development. Hydraulic fracture and downhole pressure - temperature of the 20 representative fractured wells were monitored to determine the fracturing morphology, orientation, height, occurrence and fracturing fluid filtration coefficient, liquid efficiency, in the Chang 4 ＋ 5 and Chang 6 reservoir of Nanniwan oilfield. Reliable detection results provide the basic foundation to evaluate for fracturing and water injection development work in Nanniwan oilfield and could be used as reference on the development wells deployment, fracturing parameters optimization, expanding edge exploration, oil wells converting to water in other areas.
