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 o f the sam e so rt are underba lance perforated in three kinds o f sandstones in the lab. Flow ing tests are then pe rfo rm ed. Contrast analysis on the test result show s tha t the sam e sort of shaped charges cause d ifferent pore vo lume and deg ree of dam age in d ifferent sandstone. The m a in reason fo r tha t is the diffe rence o f gra ins and cem enting m ater ia l o f diffe rent sandstone. Further know ledge is obtained from the study, wh ich he lps to prov ide theo re tica l basis fo r optim izing design.
