高压、超深井液压震击器的改进及应用

Improvement and Application of Hydraulic Jar for High Pressure and Super Deep Wells

对液压超级震击器在高压、超深井施工中震击效果差或没有震击的原因进行了分析,提出了对震击器的延时、压力平衡和密封性等方面进行改进的方法,使震击器的性能得到明显提高。

Super hydraulic top jar does not work well even does not work at total in high pressure and super deep wells in some new exploration areas in Jiangsu oilfield.This paper analyzes the cause of this and proposes a new method which improves the time-delay,pressure balance,sealing and so on,and so makes the performance of the super hydraulic jar much better.
