摘要:

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。

Abstract:

It is difficult to significantly increase the depth of the jet perforation on

sandstone targets under the existing conditions. Since sandstone has a greater influence on jet than water, three repeated perforation tests were

carried out under the condition of simulating downhole conditions. According to the requirements of national standard GB/20488-2006, the sandstone

was dried and saturated, and then consolidated in the steel shell. Then the DP44RDX383 jet perforating projectile was placed on the sandstone

target for perforating. After that, fill the water and repeat the perforation in this hole. Under the condition of 40 mm blasting height, the

initial perforation depth was 384~394 mm, the perforation depth after the second repeated perforation increased by 28% to 46%, and the pore volume

increased by 220%~367%. In the simulation of a perforator with an outer diameter of 102 mm and a centered casing with diameter of 1397 mm, the

sandstone target test was performed. The initial perforation depth was 452~534 mm, the depth of repeated perforation increased by 8%~11%, and the

pore volume increased by 176%~185%. The test showed that repeated perforation of the same hole can increase the depth of perforation and pore

volume. When the cement column was simulated by aluminum column, the depth of perforation increased obviously, but the increase of repeated

perforation was relatively reduced. This test has made a useful exploration to improve the perforating performance of jet perforating bullets, and

it is expected to be applied to actual production.
