| 摘 要： | 在实验室条件下，用同种聚能射孔弹在3种不同砂岩上进行负压射孔，然后进行流动测试。通过实验结果的对比分析，揭示了同种聚能射孔弹在不同砂岩上形成的孔道体积、损害程度不同，而组成砂岩的颗粒、胶结物性质的差异是造成这种现象的主要原因。通过研究对聚能射孔弹在不同砂岩上产生的射孔损害有了进一步的认识，希望为射孔优化设计提供理论依据。

| Abstract: | Shaped charges of the same sort are underbalance perforated in three kinds of sandstones in the lab.Flowing tests are then performed.Contrast analysis on the test result shows that the same sort of shaped charges cause different pore volume and degree of damage in different sandstone.The main reason for that is the difference of grains and cementing material of different sandstone.Further knowledge is obtained from the study,which helps to provide theoretical basis for optimizing design. |
