摘要: A shock assembly for use with a motion tool deployable into wellbore by conveyance. The includes mandrel operatively connectable to the conveyance or tool, housing (the having an opening slidingly receive and including first second spring portion), slidably positionable in portion stiffness, stiffness. stiffness being less than such that springs selectively engage as moves about response forces applied system restrict movement between whereby is vibrated.
