摘　　要：胶囊破胶剂是近年发展起来的一种新型破胶技术。它是以一种或多种常用的破胶剂为囊心 ,表面裹上一层防水的囊衣材料而形成的微小胶囊 ,具有延缓释放破胶剂的特点 ,在压裂作业中可高浓度使用而不影响其它流变性能。简述了胶囊破胶剂技术的现状、类别、特点 ,并选用国内外的部分胶囊破胶剂样品进行了室内性能评价实验。An encapsulated breaker is composed of particles that are coated with a waterproof coating, which can reduce releasing rate of the breaker. The encapsulated breaker can be used in fracturing treatment at higher concentrations and has littleinfluence on viscosities of fracturing fluid. Laboratory study on performance of the encapsulated breaker has been conducted by comparing with other products from abroad and home, which has indicated a method and results of rheological properties of the fracturing fluid.
