摘要
聚能射孔弹能量除了用于形成射流穿孔外,很大部分能量对井筒、管柱等形成负面效应。将射孔仿真研究和实验测试相结合,建立一套与实验一致的仿真研究系统和一套射孔测试系统。应用实验验证仿真数据,开展不同类型工况的射孔实验系统,获取环空位置的冲击波压力、波后流场数据。应用专业仪器处理分析测试数据,利用处理分析的测试数据验证数值仿真数据的可靠性。通过数值仿真模型提取数值仿真关键单元的压力历史曲线数据进行拟合,形成聚能射孔下环空压力的经验理论模型,为后续提高射孔弹性能和油气井完整性设计提供指导依据。
In addition to jet perforation, remaining energy from a shaped charge may apply negative effects on wellbore, string and other downhole parts. After simulation and experiments, a simulation research system which is consistent with experiment system and a perforation test system were established. Then perforation experiments were carried out to get the shock wave pressure and post-wave flow field under different working conditions. The test data were processed by professional instruments and used to verify the reliability of numerically simulated data. After extracting and fitting the history pressure curves of key numerically simulated units by the numerical simulation model, an empirical theoretical model for annulus pressure was established under the condition of perforating with a shaped charge. The model provides the basis for further improvement of perforation energy and design of well integrity.
