摘　　要：油藏非均质性是制约采收率提高的关键因素,交联聚合物微球调驱技术是解决这一问题的重要技术手段。低渗透油藏复杂的孔隙结构,深海、深井油藏中高盐、高温等恶劣油藏环境,对微球注入、封堵、深入、耐温、耐盐等性能提出了更高的要求。综述了交联聚合物微球的调驱机理、制备方法及矿场试验应用的研究进展与目前存在的问题,并提出交联聚合物微球未来研究的方向。The reservoir heterogeneity are the key factors restricting the improvement of oil recovery and are the important and difficult points in the development of oil and gas fields.The control and flooding of crosslinked polymer microspheres is an important technical means to solve this problem.However,with the development of more and more oil and gas fields with low permeability,deep sea,high temperature and deep well in recent years,the complex pore structure of low permeability reservoirs and the environment of deep sea,high temperature and deep well need higher requirements for the performance of microsphere injection,plugging,penetration,temperature and salt resistance.In this paper,the control and flooding mechanism of microspheres,preparation methods,research progress in indoor oil displacement effect and field tests,and the existing problems were mainly introduced.On this basis,the future research on microspheres were proposed.
