【摘要】：针对目前分层注水技术存在的问题及生产需求,开展了第4代分层注水技术研究,介绍了其内涵、核心工具及核心技术,分析了现场应用情况,并进行了技术发展展望。第4代分层注水技术内涵为实现注水井单井分层压力和注水量的数字化实时监测,实现区块和油藏注水动态监测的网络信息化,实现注水方案设计与优化和井下分层注水实时调整为一体的油藏、工程一体化。研发了作为核心工具的一体化配水器,开发了层段流量检测、配注量调整等关键技术,并开展了区块试验,达到了预期效果。为进一步满足生产要求,对井下层段流量检测、井筒无线通信、井下自发电和易损部件投捞技术等核心环节仍需持续攻关,并加强与油藏工程的有机结合,形成可持续支撑水驱开发的、系统的、完善的第4代分层注水技术。
[Abstract]:In view of the existing problems and production demand of stratified water injection technology at present, the fourth generation of stratified water injection technology is studied, its connotation, core tools and core technology are introduced, the field application situation is analyzed, and the technical development prospect is given. The connotation of the fourth generation of stratified water injection technology is to realize the digital real-time monitoring of the stratified pressure and water injection rate of single well in water injection wells, and to realize the network information of water injection performance monitoring in blocks and reservoirs. The reservoir is integrated with the design and optimization of water injection scheme and the real time adjustment of downhole stratified water injection. An integrated water distributor is developed as a core tool, and key technologies such as layer flow detection and flux allocation adjustment are developed, and block tests are carried out to achieve the desired results. In order to further meet the requirements of production, it is necessary to continuously tackle the key problems and strengthen the organic combination with reservoir engineering in the core links such as flow detection of downhole interval, wellbore wireless communication, downhole self-generation and salvage technology of vulnerable parts, etc. Form sustainable support water drive development, systematic, perfect 4 th generation stratified water injection technology.
