Abstract

Abstract: 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.

Key words: encapsulated breaker, fracturing fluid, breaker, release
