Radial Shock Absorber Vertical Shock Absorber For Drill Stem Testing
The Shock Absorber is used for drill stem testing service to protect pressure meansuring tools. It can also help straighten the workstring. Two types of shock absorbers are available: Vertical Shock Absorbers and Radial Shock Absorbers
The vertical shock absorber is designed to protect pressuremeasuring components from vertical shock loads and is normally run below the packer. It is always run between the gauge carrier and perforating guns. It is recommended that the vertical shock absorber be run in conjunction with a drag block assembly for effective shock absorption.
The radial shock absorber 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.
