    • A drill string comprises a mechanical drill bit and a ram accelerator with a launch tube proximate to the mechanical drill bit. A projectile accelerated by the ram accelerator exits the mechanical drill bit through an orifice and impacts a geologic formation. The impact weakens a portion of the formation, enabling the drill bit to penetrate the weakened portion more easily. An endcap may be used to prevent outside material from entering the ram accelerator. The projectile may pass through or otherwise displace the endcap during operation. The launch tube may be positioned at an angle relative to the drill bit such that projectiles impact and weaken the formation on a particular side. Contact between the drill bit and the formation may direct the drill bit toward the weakened side, enabling the ram accelerator to be used to steer the drill bit.
    • 钻柱包括机械钻头和具有接近机械钻头的发射管的冲头加速器。 被撞锤加速器加速的抛射体通过孔口离开机械钻头并撞击地质构造。 冲击削弱了地层的一部分,使钻头更容易穿透弱化部分。 端盖可用于防止外部材料进入冲头加速器。 操作期间,射弹可以穿过或以其他方式移动端盖。 发射管可以相对于钻头成一定角度定位,使得射弹撞击并削弱特定侧上的地层。 钻头与地层之间的接触可以将钻头引向弱化侧,使得油缸加速器能够用于转向钻头。

    • A downhole assembly and method are provided for selective activation of a motor in a drilling string. A rotor in a Moineau-principle motor is provided with a fluid passage therethrough and a catch that can receive and retain a blocking implement. A driveshaft is operably connected, for example using universal joints, to the rotor and a first valve component. The driveshaft is effectively supported by a thrust transmission assembly comprising a thrust unit and hanger resting on a spring so that the first valve component is not in contact with a second valve component. When a blocking implement is in place, drilling fluid activates the motor and also increases pressure on the rotor, causing the thrust transmission assembly to move the first valve component down into contact with the second valve component.
    • 提供井下组件和方法用于钻井串中的马达的选择性激活。 Moineau原理电机中的转子设置有穿过其中的流体通道和可以接收和保持阻塞工具的卡扣。 驱动轴可操作地连接到转子和第一阀部件上,例如使用万向接头。 驱动轴被推力传动组件有效地支撑,该推力传动组件包括止推单元和悬挂在弹簧上的悬挂器,使得第一阀部件不与第二阀部件接触。 当堵塞工具就位时,钻井液启动马达并且还增加转子上的压力,使得推力传动组件将第一阀组件向下移动以与第二阀构件接触。

    • Downhole rotary steerable drill including a drilling shaft rotatably supported within a housing, the drilling shaft and housing each having a longitudinal axis. The drill can include a releasable locking mechanism for rotationally locking and releasing the drilling shaft relative to the housing, the releasable locking mechanism transitionable between locked and released configurations. The releasable locking mechanism includes a sliding plunger coupled to the housing by a coupling that permits longitudinal reciprocation of the sliding plunger relative to the housing and prevents rotation of the sliding plunger relative to the housing. The releasable locking mechanism can also include pressure-responsive piston that reciprocates between an unactuated configuration and actuated configuration in response to applied pressure from a pressuring pump.

    • Implement for use in making up and breaking out of a string of a well An implement for controlling an opening (61; 161; 261) for receiving a tubular of a drill string, for reversibly closing off the opening (61; 161; 261), sealing off the opening (61; 161; 261) against the tubular and/or engaging the tubular. The implement has a carrier sleeve (62, 63; 162; 262), one or more jaws (64-66; 164; 264) carried by the carrier sleeve (62, 63; 162; 262) and mounted so as to be movable into and out of the opening (61; 161; 261). The operating sleeve (67; 167; 267) is rotatable relative to the carrier sleeve (62, 63; 162; 262) about a central axis (60; 160; 260) of the opening (61; 161; 261). The jaw (64-66; 164; 264) is coupled to the operating sleeve (67; 167; 267) for urging the jaw (64-66; 164; 264) into the opening (61; 161; 261) in response to rotation of the operating sleeve (67; 167; 267) relative to the carrier sleeve (62, 63; 162; 262). An apparatus for connecting and disconnecting tubulars of a drill string is also described.
