油田井下套管爆炸环焊技术研究

Study on Explosive Hoop-weld Technique of Downhole Casing of Oil Field

通过局部环焊技术对油田井下破损套管进行修复 ,得出简便可行的数学模型方程 ,选取切合实际的边界条件求解 ,求出了有工程应用价值的参数

The part explosive hoop weld technique was used for mending destroy casing on downhole of oil field. And a simply maths model was obtained. When the equation was solved by suitable boundary conditions, the fit explosive charge was obtained. It is worthy of apply on engineering.
