摘要
注水油藏开发中后期非均质性加剧,高温、高盐环境也对化学驱的实施提出了更高的要求,化学驱的应用面临新挑战。为此,该文对聚合物驱、表面活性剂驱、碱驱、多元复合驱技术的应用情况及存在问题进行了全面总结,并分析有机碱三元复合驱、无碱二元复合驱、非连续化学驱、纳米复合驱等驱替技术的发展现状。明确了驱油体系性能在稳定性、适应性、评价方法、储层损害等方面存在的技术瓶颈及挑战,对低伤害化学驱油体系、复合驱智能化发展等技术进行展望。该研究对化学驱的研究与应用提供了参考。
In the middle and late stages of water-flooding development in oil reservoirs,the intensification of heterogeneity and the high-temperature,high-salinity environment impose greater demands on the implementation of chemical flooding,presenting new challenges for its application.For this reason,this paper provides a comprehensive summary of the application status and existing issues of polymer flooding,surfactant flooding,alkali flooding,and polycomplex flooding technologies.Additionally,it analyzes the current development status of organic alkaline ternary combination flooding,alkaline-free binary combination flooding,non-continuous chemical flooding,and nanocombination flooding technologies.The study identifies technical bottlenecks and challenges in the performance of oil displacement systems regarding stability,adaptability,evaluation methods,and reservoir damage.It also offers an outlook on low-damage chemical flooding systems and the intelligent development of combination flooding technologies.This study serves as a reference for the research and application of chemical flooding in the oil industry.
