    • Apparatus for drilling a bore hole comprises a hammer (3) and a series of dual wall drill tubes (2). The hammer (3) is supplied with compressed air and is for use in applying successive percussive blows to a percussive drill cutting bit for taking core samples from the bottom of the bore hole while drilling same. An upstanding rig (37) is provided at surface level to support the hammer (3) and drill tubes (2) and to transmit push-down or pull-up movement thereto. First means (32) indexes rotationally the bit for drilling purpose and is operable by a portion of the supply of air. Second means conducts from the bottom end of the bore hole that portion of air used by and exhausted from the percussive cutting bit (27) and having core particles entrained therein. Third means comprises an annular flushing jet (7) to direct a portion of air upwardly through a sampling tube (6) co-axial with the drill tube (2) and hammer (3) to induce a venturi to assist in conducting core particle entrained exhaust air upwardly.
    • 用于钻孔的装置包括锤(3)和一系列双壁钻杆(2)。 锤子(3)被供给压缩空气,并且用于将冲击式冲击施加到冲击钻头切割钻头,以在钻孔的同时从钻孔的底部取出岩心样品。 在表面一级提供了一个直立式装置(37),以支撑锤(3)和钻管(2)并向其传递下推或上拉运动。 第一种方式(32)旋转钻头用于钻孔目的,并且可由空气供应的一部分进行操作。 第二装置从钻孔的底端开始由冲击切削钻头(27)使用并从其中排出并且具有夹带在其中的核心颗粒的部分空气。 第三装置包括环形冲洗喷嘴(7),以将一部分空气向上引导通过与钻管(2)和锤(3)同轴的采样管(6),以引导文氏管来辅助导入核心颗粒夹带 排气向上。

    • There is disclosed a downhole tool for generating a longitudinal mechanical load. In one embodiment, a downhole hammer (10) is disclosed which is activated by applying a load on the hammer and supplying pressurised fluid to the hammer. The hammer includes a shuttle valve (14) and a piston (16) that are moveable between first and further positions, seal faces (18, 20) of the shuttle valve (14) and piston (16) being released when the valve and the piston are in their respective further positions, to allow fluid flow through the tool. When the seal is released, the piston (16) impacts a remainder of the tool to generate a mechanical load. The mechanical load is cyclical by repeated movements of the shuttle valve (14) and piston (16).
    • 公开了用于产生纵向机械载荷的井下工具。 在一个实施例中,公开了一种井下锤(10),其通过在锤上施加负载并将加压流体供应到锤来激活。 锤子包括梭阀(14)和活塞(16),活塞可在第一和另外的位置之间移动,梭阀(14)的密封面(18,20)和活塞(16)在阀和阀 活塞处于其各自的另一位置,以允许流体流过工具。 当密封件被释放时,活塞(16)冲击工具的其余部分以产生机械载荷。 机械载荷通过梭阀(14)和活塞(16)的重复运动而循环。
