Research on the Application of Accumulaled Energy Effect of High Energy Gas Fracturing

本文简略介绍了凝聚炸药爆轰波基本方程及其参数的近似计算;对实用中的混合装药性能参数的确定、裸眼井聚能装药定向开裂造缝原理、造缝深度估算及其影响因素、套管井聚能复合射孔造缝提示等作了探讨性说明.指出聚能效应在我国特殊油气藏的开发中,作为预处理技术,将发挥巨大作用.

This paper introduces the basic equation of detonating wave of condensed explosives and approximate calculation of its parameters. It also illustrates the definition of performance parameters of mixed charging in practice; the principles of directional crack making, estimation of crack depth and affecting factors in regard to shaped charge in open hole; crack making by compound perforation of shaped charge in cased hole, and so on. As a technology of pretreatment, the accumulated energy effect will play a great role in the exploitation of special oil — gas reservoirs.
