摘要： A drilling liner having a core bit at its bottom end is carried along with a pilot bit on an inner bottom hole assembly driven by a downhole mud motor. In one embodiment, the motor is powered by mud carried by an inner string. Alternatively, the inner string may be omitted and the flow of mud through the liner powers the motor: this requires a locking tool for locking the motor assembly to the outer assembly. Once an abnormally (high or low) pressured zone has been traversed, the liner is set as a casing, the inner assembly is pulled out, and drilling may be resumed using a conventional tool. Directional drilling is accomplished by having an MWD device for providing directional information and having directional devices on the inner and outer assembly. These include retractable steering pads. Expandable bits, under-reamers and jetting nozzles may also be used in the drilling process. One embodiment of the invention has a bottom thruster between the mud motor and the drill bits that makes it possible to continue drilling for a limited distance even if the upper portion of the casing is stuck.
摘要翻译：在其底端具有芯钻头的钻井衬套与由井下泥浆马达驱动的内底孔组件上的导向钻头一起运送。在一个实施例中，马达由内部绳子承载的泥浆供电。或者，可以省略内部串，并且通过衬套的泥浆的流动为电动机供电：这需要用于将电动机组件锁定到外部组件的锁定工具。一旦异常（高压或低压）的压力区域被穿过，衬套被设置为外壳，内部组件被拉出，并且可以使用常规工具恢复钻孔。定向钻孔是通过具有用于提供方向信息并在内部和外部组件上具有定向装置的MWD装置来实现的。这些包括可伸缩转向垫。在钻井过程中也可以使用可扩展钻头，扩孔钻机和喷射喷嘴。本发明的一个实施例在泥浆马达和钻头之间具有底部推进器，使得即使套管的上部被卡住，也可以继续钻孔有限的距离。

摘要： One exemplary APD Device is used with a liner drilling assembly to control wellbore pressure. The APD Device reduces a dynamic pressure loss associated with the drilling fluid returning via a wellbore annulus. Another exemplary APD Device is used to control pressure in a wellbore when deploying wellbore equipment, including running, installing and/or operating wellbore tools. The APD Device is set to reduce a dynamic pressure loss associated with a circulating fluid. The APD Device can also be configured to reduce a surge effect associated with the running of the wellbore equipment. Still another APD Device is used to control pressure in a wellbore when completing or working over a well. Exemplary completion activity can include circulating fluid other than a drilling fluid, such as a gravel slurry. The APD Device can reduce the dynamic pressure loss associated with circulation of both drilling fluid and non-drilling fluid.

摘要： A drilling system includes a steerable bottomhole assembly (BHA) having a steering unit and a control unit that provide dynamic control of drill bit orientation or tilt. Exemplary steering units can adjust bit orientation at a rate that approaches or exceeds the rotational speed of the drill string or drill bit, can include a dynamically adjustable articulated joint having a plurality of elements that deform in response to an excitation signal, can include adjustable independently rotatable rings for selectively tilting the bit, and/or can include a plurality of selectively extensible force pads. The force pads are actuated by a shape change material that deforms in response to an excitation signal. A method of directional drilling includes continuously cycling the position of the steering unit based upon the rotational speed of the drill string and/or drill bit and with reference to an external reference point.

摘要： A device and system for improving efficiency of subterranean cutting elements uses a controlled oscillation super imposed on steady drill bit rotation to maintain a selected rock fracture level. In one aspect, a selected oscillation is applied to the cutting element so that at least some of the stress energy stored in an earthen formation is maintained after fracture of the rock is initiated. Thus, this maintained stress energy can thereafter be used for further crack propagation. In one embodiment, an oscillation device positioned adjacent to the drill bit provides the oscillation. A control unit can be used to operate the oscillation device at a selected oscillation. In one arrangement, the control unit performs a frequency sweep to determine an oscillation that optimizes the cutting action of the drill bit and configures the oscillation device accordingly. One or more sensors connected to the control unit measure parameters used in this determination.

摘要： An active differential pressure device (APD device) in fluid communication with a returning fluid creates a differential pressure across the device, which controls pressure below the APD Device. In embodiments, a control unit controls the APD Device to provide a selected pressure differential at a wellbore bottom, adjacent a casing shoe, in an intermediate wellbore location, or in a casing. In one arrangement, the control system is pre-set at the surface such that the APD Device provides a substantially constant pressure differential. In other arrangements, the control system adjusts an operating parameter of the APD Device to provide a desired pressure differential in response to one or more measured parameters. Devices such as an adjustable bypass can be used to control the APD Device. In other embodiments, one or more flow control devices coupled to the return fluid reduce the effective pressure differential provided by the APD Device.

摘要： An APD Device provides a pressure differential in a wellbore to control dynamic pressure loss while drilling fluid is continuously circulated in the wellbore. A continuous circulation system circulates fluid both during drilling of the wellbore and when the drilling is stopped. Operating the APD Device allows wellbore pressure control during continuous circulation without substantially changing density of the fluid. The APD Device can maintain wellbore pressure below the combined pressure caused by weight of the fluid and pressure losses created due to circulation of the fluid in the wellbore, maintain the wellbore at or near a balanced pressure condition, maintain the wellbore at an underbalanced condition, reduce the swab effect in the wellbore, and/or reduce the surge effect in the wellbore. A flow restriction device that creates a backpressure in the wellbore annulus provides surface control of wellbore pressure.
