石油射孔弹射孔剩余能量理论与实验研究
首发时间:2011-07-29
摘要:在射孔-测试联作技术施工过程中,射孔弹井下爆炸后产生的强烈冲击作用可能导致测试管柱、封隔器和套管等发生损坏或失效。本文通过对射孔弹井下爆炸过程、作用效应及能量转换等进行理论分析,结果表明:射孔剩余能量是导致测试管柱、封隔器和套管发生损坏或失效的能量源头;当只关注射孔弹井下爆炸后在射孔液中产生的瞬态压力场及其冲击破坏效应时,射孔完井过程可以简化为普通炸药装药在射孔液中的爆炸。根据能量等效原理,应用水下爆炸能量法和Cole公式对三种常用的高温型射孔弹的井下射孔剩余能量进行了实验研究,获得了其射孔剩余能量的当量炸药质量。

Theoretical and Experimental Research on Perforation Remnant Energy
Abstract:During the perforating and testing combination, the tubing, packer and casing are strongly impacted by shock-wave generated from oil perforators would be damaged. The energy conversion and energy equivalent theories and the underwater explosion energy method are applied to investigate the perforation remnant energy. The theoretical analysis results indicate that the explosion remnant energy of the perforators is the main energy source causing damage of the tubing, packer and casing. When the dynamic pressure waves and their impact effect are only paid attention to, the explosion process of the perforators with guns in the oil well can be simplified to the explosion of ordinary explosive charges in the perforation liquid. The perforation remnant energy, TNT equivalent and HMX equivalent of three type perforators are obtained by experiments and Cole Formula.
