摘要:
设计了一种球锥结合药型罩石油射孔弹，在半球形主药型罩基础上增加了锥形前驱罩结构，利用ALE方法，模拟了药型罩材料为铜，锥角角度分别为30°、35°、40°、45°和50°时对其射流的速度和形状、射流头部速度和杵体质量的影响，并与半球形药型罩模拟结果进行对比。结果表明前驱罩锥角40°比锥角30°射流速度降低了26%，直径提高了8.1%，锥角40°比锥角50°射流速度提高了4.1%，直径降低了3.4%。前驱罩锥角为40°和50°的球锥形药型罩的射流头部速度比半球形药型罩分别提高了25%和20%，直径分别提高了2.6%和6.1%。试验结果与模拟结果大致相符，为大孔径、深穿孔石油射孔弹的设计开发提供了一定的参考。
Abstract:
A petroleum perforating charge with hemispheric-conical combined liner was designed. The hemispheric liner was combined with a conical precursory shaped charge. ALE methods were used to numerical simulate the speed and shape of jet, velocity of jet head, and mass of slug of the petroleum perforating charge when the liner material was copper and the cone angle were 30°, 35°, 40°, 45° and 50°. The simulation results were also compared with those of the hemispheric liner. Compared with the liner with 30° cone angle, the jet velocity of liner with 40°cone angle reduces 26% and the diameter improves 8.1%. Compared with the liner with 50° cone angle, the jet velocity of liner with 40°cone angle improves 4.1% and the diameter reduces 3.4%. When the cone angle was 40° and 50°, the velocities of the jet respectively improves 25% and 20% than hemispheric liner, and the diameter respectively improves 2.6% and 6.1%. The test results are similar to the simulation. Relevant fundamental data are provided here for the research and development of large and deep aperture perforating charge.
