摘要:: 针对套管孔眼大小不一致造成页岩气井水力加砂压裂施工难度大的问题，从国外引进了一种Stimstream等孔径深穿透射孔弹，分析了其结构特点，并和国产射孔弹进行了地面环靶试验和现场应用效果比较。结果表明：该射孔弹套管孔眼受射孔枪和套管间隙大小影响不大,对降低水力加砂压裂破裂压力和施工压力具有明显的效果。

Abstract:: Regarding to the problems of hydraulic fracturing in shale gas wells caused by the inconsistent size of casing hole, Stimstream shaped charge providing equal aperture and deep penetration was imported from US. Its special structure was analyzed. Target test and oilfield application effect of this charge were compared with charges made in China. The results show that this charge can provide equal aperture on the casing regardless of different clearance between gun and casing, and it has remarkable effect on reducing the breakdown pressure and treated pressure of formations.
