孤岛油田已投入注聚合物驱7个区块。注聚合物开发8年来,在完善注聚区注采系统、处理极端油压井、治理层系间窜漏等方面进行了深入分析研究和矿场实践,形成了一些比较合理的方法和配套技术。同时运用数模技术在优化注聚参数、合理提液时机和提液幅度、对外围水井降水降压加快边角井见效的时机和幅度等方面进行了深入的研究,并且把研究成果及时的运用于矿场注聚油藏的注采调整和现场管理工作中,明显的改善了注聚开发效果。
Gudao has injected polymer flooding 7 blocks. In the past 8 years since the polymer was developed, we have conducted in-depth analysis and research and mine practice in perfecting the injection-production system in injection-polymerized area, handling extreme hydraulic fracturing wells, and managing leakage between the management systems, forming some reasonable methods and supporting technologies . In the meantime, the application of digital-to-analog technology in the aspects of optimizing injection-polymerization parameters, timing and level of liquid extraction, and the timing and amplitude of reducing the pressure of the peripheral water wells to accelerate the efficiency of the corner well has been studied in depth. In the field of injection-production adjustment and on-site management of the injection-injection reservoir in the mine, the effect of injection-injection development is obviously improved.
