摘要： Apparatus for an improved method for drilling earthen boreholes with a fluid powered rotary motor mounted on the downhole end of a non-rotating, fluid conducting drill string has a fluid powered, axially reciprocating hammer coupled to the motor by means of a rotary coupling having freedom for axial movement, so that the hammer will be rotated by the motor and the motor will be axially isolated from the reciprocating hammer as both are powered by fluid conducted from the surface through the drill string.

摘要： A downhole percussion drilling apparatus includes a housing and a piston rotatably supported within an interior bore of the housing. A first engagement surface serves as a cam surface. A second engagement surface serves as a follower surface. The cam surface has a plurality of inclined planes each of which terminates in a drop off. With each rotation of the piston, the follower surface rises up each of the inclined planes and then falls down each of the drop offs of the cam surface thereby imparting a series of percussive hammering impacts to the piston.
摘要翻译：井下冲击钻探装置包括壳体和可旋转地支撑在壳体的内孔内的活塞。第一接合表面用作凸轮表面。第二接合表面用作从动表面。凸轮表面具有多个倾斜平面，每个倾斜平面终止于脱落。随着活塞的每次旋转，从动表面上升每个倾斜平面，然后落下凸轮表面的每个下落，从而对活塞施加一系列冲击锤击。

摘要： An improved anti-jamming mechanism for use in a coring tool is devised by providing a rotary jar within the inner barrel of the coring tool. The inner barrel is connected to a bearing assembly into which a bearing shaft is axially and concentrically disposed. The bearing assembly is rotatably journaled to the bearing shaft. The bearing shaft is rotatably and longitudinally fixed with respect to the outer barrel of the coring tool. The bearing shaft and bearing assembly are longitudinally displaceable with respect to each other by Bellville washers. The bearing assembly also includes a rotary anvil which is ultimately brought into contact with a rotary hammer which in turn is fixed with respect to the outer barrel. An impulsive torsional and longitudinal force is imparted by the rotary hammer to the rotary anvil through the resilient coupling between the bearing shaft and bearing assembly disposed within the inner barrel.
摘要翻译：通过在取心工具的内筒内设置旋转罐，设计了用于取芯工具的改进的抗干扰机构。内筒连接到轴承组件，轴承轴轴向和同心地设置在轴承组件中。轴承组件可旋转地轴颈支承在轴承轴上。轴承轴相对于取芯工具的外筒旋转并纵向固定。轴承轴和轴承组件可以由Bellville洗衣机相对于彼此纵向移位。轴承组件还包括旋转砧座，其最终与旋转锤接触，旋转锤相对于外筒固定。旋转锤通过轴承轴和设置在内筒内的轴承组件之间的弹性联接，将旋转锤施加到旋转砧上。

摘要： A rotary drive member such as a drill string, has a housing rotatably mounted at its lower end and an axial-throw cam is fixed at the lower end of the drive member in the housing. Chisel blades are axially slidable in the housing and are reciprocated by the cam in such manner that two dimetrically opposed blades are lifted and then forcibly driven downward while other chisel blades are left in contact with the well bottom to intermittently hold the housing against rotation. The chisel blades are sharpened in such a way that they tend to rotate the housing through a small angle at each downward impact.
摘要翻译：诸如钻柱的旋转驱动构件具有可旋转地安装在其下端的壳体，并且轴向凸轮凸轮固定在壳体中的驱动构件的下端。凿刀片在壳体中可轴向滑动并且通过凸轮往复运动，使得两个两个相对的相对的叶片被提升然后被强制地向下驱动，而其他凿刀片与井底保持接触以间歇地保持壳体的旋转。凿子刀片以这样的方式被磨削，使得它们倾向于在每个向下的冲击下使壳体旋转小角度。
