A jar up, bump down hydraulic drilling jar is disclosed. A hydraulic tripping valve (46) arrangement permits the storage of large amounts of static force before releasing a hammer (56) to strike an anvil surface (58) with substantial force. The hammer (56) is positioned on the mandrel (8) and interacts with the anvil surface (58) in the housing (10) to deliver upward jarring forces, to the drill string. During the downward jarring movement, the tripping valve (46) is opened to prevent pressure buildup and accidental jarring; thus, a single acting drilling jar is formed.

Cette invention se rapporte à une coulisse de forage hydraulique à battage vers le haut et à cognement vers le bas. Un système de vanne à déclenchement hydraulique (46) permet d'emmagasiner de grandes quantités de force statique avant de libérer un marteau (56) qui vient heurter une surface de butée (58) avec une force considérable. Le marteau (56) est positionné sur le mandrin (8) et agit en coopération avec la surface de butée (58) dans le logement (10) pour imprimer au train de tiges des forces de battage dirigées vers le haut. Pendant le mouvement de battage descendant, la vanne à déclenchement (46) s'ouvre pour empêcher toute accumulation de pression et tout battage accidentel. Une coulisse de forage à action simple est ainsi formée.
