综述了无机颗粒、体膨颗粒和聚合物微球等颗粒类调堵剂的研究进展，包括堵剂配方、颗粒与地层孔喉匹配性的研究进展，剖析了研究与应用中存在的问题：无机颗粒不耐冲刷，有效期短；水膨体膨胀倍数高、膨胀速度快、强度和稳定性低，难与地层匹配；颗粒与地层孔喉匹配性的研究不能充分考虑诸多影响因素如颗粒类型和性质、颗粒级配、颗粒浓度和注入速度、地层非均质性等；且缺少充分考虑上述影响因素的理论模型。在此基础上，给出了颗粒类堵剂的研究方向和发展趋势：无机颗粒应复合其他材料使用；体膨颗粒的使用应根据需要引入橡胶、塑料、阳离子材料及耐温耐盐单体，且其粒径范围需要拓宽；颗粒与地层孔喉的匹配关系需要充分考虑多种影响因素，同时需要建立考虑多种影响因素和实际情况的理论模型；物理模拟也需要更切合渗流和地质条件。

A summary of research progress of inorganic particle, volume expansion grain, polymer microsphere and other particle proifle-control plugging agents is provided, including formula of plugging agents and research progress in compatibility between particles and stratum pore throats. Problems existing in research and application are analyzed, including inorganic particles feature poor washout resistance and short effective period. Water-swelling polymer features high swelling multiple, fast swelling speed, low strength and stability, and is hard to match with stratum.The research on compatibility of particles and stratum pore throats fails to be in full consideration of many affecting factors, such as particle type and properties, grain composition, particle concentration, injection speed, heterogeneity of stratum. And lack of a theoretical model in full consideration of the above affecting factors. Research direction and development trend of particle plugging agents are pointed out on this basis: inorganic particles shall be used in combination with other materials. The use of volume expansion grains requires introduction of rubber, plastic, cation materials as well as temperature-resistant and salt-tolerant monomer as needed, and range of particle size needs to be widened.Multiple affecting factors shall be taken into full consideration for the compatibility between particles and stratum pore throats, and a theoretical model in consideration of multiple affecting factors and actual conditions shall be established. Physical simulation is also required to suit seepage and geological conditions.
