中国首个长期弃置的深水油田由于二次开发面临复杂的技术难题和较低的经济效益等问题,成为难以动用的边际油田.通过GGRP(地球物理-地质-油藏-生产)一体化技术研究与实践,盘活弃置油田,保障高产稳产.针对剩余油分布的不确定性、构造复杂、储层非均质及水下管汇限温等问题,克服了多项前沿技术难点.这些创新技术包括长期水驱关停油田的剩余油预测技术、复杂油藏的地质导向及精细描述技术、油藏管流耦合模型流动保障技术,成功指导了油田的二次开发,显著提升了油田的开发效果.结果表明:该油田初期产能跃居南海东部油田前三,实际含水上升趋势与方案设计基本一致,预计增加可采储量达259x104m3.这一开拓性研究为长期弃置深水油田二次开发提供了宝贵的经验,该科技成果在同类油田的开发进程中有着广泛的应用前景.
Innovation and practice of secondary development technology for China's first long-term abandoned deepwater oilfield
China's first long-term abandoned deepwater oil field has become a marginal oil field that is difficult to exploit due to complex technical difficulties and low economic benefits faced by secondary development.Through the research and practice of GGRP(geophysics-geology-reservoir-production)integrated technology,abandoned oil fields are revitalized to ensure high and stable production.In order to cope with the challenges of uncertainty in the distribution of remaining oil,structural complexity,reservoir heterogeneity and temperature limitations of underwater manifolds,we have overcome a series of cutting-edge technical problems.These innovative technologies include remaining oil prediction technology for long-term water flooding shut-in oil fields,geological guidance and fine description technology for complex oil reservoirs,and reservoir pipe flow coupling model flow assurance technology.They have successfully guided the secondary development of oil fields and significantly improved improve the development effect of oil fields.The results show that the initial production capacity of the oil field has jumped to the top three oil fields in the eastern South China Sea.The actual water content rising trend is basically consistent with the plan design,and the increase in recoverable reserves is expected to reach 259x104 m3.This pioneering research provides valuable experience for the secondary development of long-term abandoned deepwater oil fields.This scientific and technological achievement has broad application prospects in the development of similar oil fields.
