摘　　要：水力深穿透射孔系统利用高压水射流钻孔的方式实现深穿透射孔。其射孔孔眼深、孔径大,射孔通道的流通能力为常规射孔的10-20倍,适用于高污染井、低渗透地层、薄油层等的近井带改造及低渗透油气藏、裂缝性油气藏、底水或气顶油气藏等特殊油气藏的开发。国内外应用实例分析表明,水力深穿透射孔经济效益显著,发展前景广阔。Water-power deep penetrator system can perforate clearly drainage channel utilizing the principle of high pressure jet cutting. The drainage channel has characters of longer depth, bigger radius and stronger flow ability which is 1020 times of conventional shaped charge perforation. It is not only suit for ameliorating the formation of old well, low permeability reservoir and thin strata, but also be used to exploit low permeability reservoir, fracture reservoir, bottom-water or top-gas reservoir. The applications in domestic and abroad imply that this technique will has a promising prospect in the future.
