7" radial shock absorber in stock

The radial shock absorber protect pressure-measuring equipment or sensitive components in the workstring for shock loads transmitted through the workstring by firing of TCP guns. It can also help straighten the workstring.

This tool is mainly composed by radial shock absorption component and axial slide component. The radial shock absorption component include block retainer , housing retainer,block , block spring retention and spring. The axial slide component include housing retainer, lower adapter, mandrel , shear pin , lower bearing thrust and ring shear

Normally the radial shock absorber use with the vertical shock absorber together and it is always located below the vertical shock absorber. In radial shock absorbers, spring-loaded drag blocks absorb radial shock waves transmitted through the TCP perforating. The vertical shock from axial slide can be transferred to the vertical shock absorber, a part of shock will be absorbed by axial slide movement and the shear pin effect, so that the condition of radial shock absorber component and inner-wall tubing are relative stable.
