复合压裂技术研究

A Research on Combination Fracturing Technique

复合压裂技术是将高能气体压裂和水力压裂相结合的一种新型的增产增注技术。通过对几种不同压裂方法的比较，阐述了复合压裂技术的增产机理和设计原则，现场统计表明，复合压裂工艺增产效果明显好于单纯的水力压裂或高能气体压裂工艺，且不会对套管和水泥环造成破坏。

Combination fracturing is a new production and injection stimulation technique which combines high energy gas fracturing with hydraulic fracturing． The production stimulation mechanism and design principles are discussed based on comparison of several different fracturing methods． Field statistics show that the production stimulation effect of combination fracturing are much better than that of hydraulic fracturing or high energy gas fracturing and does not damage string and cement sheath．
