【摘要】 传统的射孔工艺在遇到薄层多而且相距较远的油气井时,效率低下且危险性大。本文研究了在一次射孔过程中携带多节射孔枪,进行多次射孔作业的射孔工艺。主要介绍了该系统中选发器的工作原理,并就其重要组件——计数译码器的工作原理与工作过程进行研究,对该射孔系统进行了过电缆试验与高温试验,系统工作正常。更多还原

【Abstract】 The traditional perforating process for the oil-gas well having many thin layers and longer distance between the layers is inefficient and dangerous. The perforating process of perforating many times during one procedure is studied. The principle of ignition selector is introduced, and the principle and process of counting decoder are studied. The perforating system works well under over-voltage and high temperature tests.更多还原
