摘要
叙述了爆炸焊接法修复油田井下损伤套管用排液燃气发生器的工作原理,分析了燃气发生器产生的气体对油田井下套管修复时液体流向的作用,并对排液燃气发生器的火药装药量、燃烧室压力、喷嘴尺寸、点火压力、点火药量及壳体强度进行了理论分析和计算。结果表明,利用火药燃烧气体做功所设计的排液燃气发生器可以快速排除套管与焊接加固管之间的井液,可以显著提高爆炸法修复套管的效果。
The mechanism of propellant＇ draining generator for repairing the casing by explosive welding is described. The fluid-flow direction drived by combustion gas is analyzed. The charge weight, chamber pressure, nozzle dimension, ignition pressure, ignition agent weight and shell strength of the generator are also analyzed theoretically and calculated. The results show that the generator can rapidly drain off well fluid between casing and welded reinforcing pipe through combustion gas doing work, which has good effect on improving explosive welding for casing.
