页岩气藏水力压裂和爆燃压裂对比分析

Comparative analysis of hydraulic and propellant fracturing for shale gas

本文采用Mancos页岩现场和实验室数据,比较了水力压裂和爆燃压裂这两种压裂技术。最终得出结论:在应力实验中,爆燃压裂不适用于硬地层,页岩中的砂岩层极大地限制裂缝发育。现场测试说明,只要选择合适的状况,爆燃压裂和水力压裂都可以使用。

This paper describes laboratory and field experiments that are conducted to compare hydraulic and propellant fracturing in the Mancos Shale.The results of this work conclude that:the propellant is not suitable for stiff strata due to the growth of fractures are constrained by the sand rock around.Both technologies can provide stimulation benefits,but only when applied in appropriate situations.
