hard trip and sticking accidents.It is a first selected tool for directional well,complicated well and deep well.


2.Features


2.1These jars have a mechanical structure, the slips’s stored energy slippage composes its shock principle.
2.2A special flexible joint can effectively reduce the jar body’s bending stress.
2 .3There is not high pressur e i n t he hydraulic oil reservoir,the oil can be only used as lubrication,the

changing of the oil quanlity won’t affect the shock effects.
2.4The jarring force should be adjusted on surface,the force will keep still,so we can get a constant shock force.
2.5Reasonable structure,advanced manfacturing process can make our jar reliable.
