摘要： A shock tool (120) for reciprocating a drillstring (20) includes an outer housing (130) and a mandrel assembly (150) coaxially disposed in the outer housing (130). The outer housing (130) has a radially inner surface (132) including a plurality of circumferentially-spaced splines (134). The mandrel assembly (150) includes a mandrel (160) having a radially outer surface (161) including a plurality of circumferentially-spaced splines (166) and a plurality of circumferentially-spaced troughs (168). Each spline (134) of the outer housing (130) is disposed in one trough (168) of the mandrel (160). Each spline (166) of the mandrel (160) includes a top surface (166e), a first lateral side surface (166g) extending radially from the top surface (166e), a second lateral side surface (166f) oriented parallel to the first lateral side surface (166g), and a bevel (166h) extending from the top surface (166e) to the second lateral side surface (166f). Each spline (166) of the mandrel (160) also includes a pocket (166j) in the second lateral side surface (166f) extending radially from a bottom surface (168a) of a trough (168) to the bevel (166h).
