摘要： A retrievable core sampling assembly for latching to or relative to a rotatable tubular housing of a core sampling apparatus to allow the capture and retrieval of a core from a subterranean formation, the assembly comprising or including: a core catcher barrel for a core, the barrel being rotationally isolated from the tubular housing and cooperable with a core taking bit coupled to the rotatable tubular housing to retain a core, and a hammer for providing impact to the core taking bit along a longitudinal impact path that is or is substantially decoupled from the core catcher barrel so that when latched, rotation and impact of the core taking bit captures and passes core material from the formation to the core catcher barrel in manner that isolates a core in the core catcher barrel from rotation and impact forces.
