坪北油田应用吸水剖面测井改善开发效果研究

Water Sucking Section Logging Applied to Pingbei Oilfield for Improving Development Effect

坪北油田综合含水达55.2%,采出程度为6.12%。为提高坪北油田的采收率,确保油田继续稳产,从同位素示踪测井找窜、吸水剖面研究的原理着手,结合坪北油田的动态变化情况,优选33口油水井进行吸剖和同位素找窜测井,开展对测井结果的分析研究,并以此为依据进行注采调整和挖潜工作,取得了良好的效果。

Overall water content reaches to 55.2% and recovery rate to 6. 12% in Pingbei Oilfield. in order to improve its recovery rate and ensure its stable yield, starting with the theories on channeling location through isotopic tracing logging and water sucking section and combing with dynamic change in Pingbei Oil- field, this paper optimizes 33 oil--water wells for water sucking section logging and isotopic--based channe- ling location logging and analyzes the logging results. On this basis, efforts are made to adjust injection-- production plan and dig the potential.
