摘要:
聚能射孔彈能量除了用于形成射流穿孔外,很大部分能量對井筒、管柱等形成負面效應。將射孔仿真研究和實驗測試相結合,建立一套與實驗一致的仿真研究系統和一套射孔測試系統。應用實驗驗證仿真數據,開展不同類型工況的射孔實驗系統,獲取環空位置的沖擊波壓力、波后流場數據。應用專業儀器處理分析測試數據,利用處理分析的測試數據驗證數值仿真數據的可靠性。通過數值仿真模型提取數值仿真關鍵單元的壓力歷史曲線數據進行擬合,形成聚能射孔下環空壓力的經驗理論模型,為后續提高射孔彈性能和油氣井完整性設計提供指導依據。
Abstract:
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.
