作者李东传,曹振斌（2019）在《聚能射孔器同孔重复射孔作用效果试验研究》一文中研究指出：现有技术条件下很难在砂岩靶上大幅提高聚能射孔深度,基于砂岩比水对射流影响更大的实际,模拟井下条件,开展了三次重复射孔试验。按GB/20488-2006要求干燥、饱和砂岩并固结在钢壳内,将DP44RDX38-3型聚能射孔弹放置在砂岩靶上射孔,然后将孔道内注满清水,对准孔道重复射孔。在40 mm炸高条件下,初次射孔深度为384～394 mm,二次重复射孔后穿孔深度增加28%～46%,孔容增加220%～367%;在模拟外径102 mm射孔器、139.7 mm套管居中条件下,做砂岩靶试验,初次射孔深度452～534 mm,重复射孔穿孔深度增加8%～11%,孔容增加176%～185%。试验表明,同孔重复射孔能够提高穿孔深度和孔容,用铝柱模拟水泥环后穿孔深度增加明显,但重复射孔增加幅度相对减少。该试验为提高聚能射孔弹的射孔性能做了有益探索,有望应用于生产实际。
