摘要
G5-71井区具有小断块发育、构造破碎、油气层厚度大、储层物性好的特点,目前整体处于高含水期。为提高储量动用程度、完善注采井网,本文在落实井区地质特征的基础上,通过开展注水效果、增产增注措施效果评价,分析井区综合调整潜力,完成以NmⅡ-8、NmⅢ-3、NmⅢ-8小层为主力层的方案部署。方案实施后,多项开发指标得到改善,多口新井获得高产,方案的成功实施对于同类型井区的进一步调整开发具有较好的借鉴意义。
G5 -71 wellblock has the characteristics of developed minor fault blocks, crushing structure, large reservoir thickness, good reservoir properties, and is currently in high water - cut. In order to improve the use of reserves and perfect injection - production patterns, through the implementation of the geologic characteristics of wellblock, to carry out water injection effect and measure effect evaluation, comprehensive adjustment potential of wellblock was analyzed, and the adjustment deployment on injection - production pattern has been carried out to focus on Nm Ⅱ - 8, NmⅢ - 3,NmⅢ - 8 as the main layer. After the implementation of the deployment,some development indicators have improved and several new wells have achieved high production. The successful implementation of the adjustment deployment is a good reference for the further development and adjustment of the same type wellblock.
