机械震击器是钢丝作业中钢丝基本工具串必不可少的工具,各种工具的投捞剪切销钉都是通过震击器的工作来完成的。然而在较深井作业或者油稠、井斜大等较差的井况下,机械震击器无法完全发挥其功能,这时候需要通过液压震击器来辅助其完成震击作业。 Mechanical jarring is an indispensable tool for the basic tool string of steel wire in wire work. The fishing pin cutting of various tools is accomplished through the work of the jar. However, in deeper well operations or oil thicknesses and poor wellbore conditions, the mechanical jarring device can not fully perform its function. At this time, it needs to be assisted by a hydraulic jar to complete the shock operation.
