摘要： A face conveyor includes a continuous conveyor formed by a conveyor chain with entrainment plates that are connected to chain links and which, when conveying, circulates in an outward run and a return run, each of which are guided in trough portions by trough elements, which are arranged in a row. Guides provided on each trough element include a first guide on a working face side and a second guide at a spacing from a goaf side. The first guide on the working face side is secured on the trough element between the outward run and the return run. The outward run and the return run extend in a laterally offset manner with respect to each other, and the trough portion guiding the entrainment plates in the outward run is open on the working face side.

摘要： An oscillating shear valve system for generating pressure fluctuations in a flowing drilling fluid comprising a stationary stator and an oscillating rotor, both with axial flow passages. The rotor oscillates in close proximity to the stator, at least partially blocking the flow through the stator and generating oscillating pressure pulses. The rotor passes through two zero speed positions during each cycle, facilitating rapid changes in signal phase, frequency, and/or amplitude facilitating enhanced, multivalent data encoding. The rotor is driven by a motorized gear drive. In one embodiment, a torsional spring is attached to the motor and the resulting spring mass system is designed to be near resonance at the desired pulse frequency. The system enables the use of multivalent encoding schemes for increasing data rates.

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 method of transmitting pressure pulses from a downhole location through a flowing fluid in a wellbore comprises using a linear actuator to controllably move a reciprocating member axially back and forth between a first position and a second position to at least partially obstruct flow of the flowing fluid to generate the pressure pulses. A reciprocating pulser for generating pressure pulses in a fluid flowing in a wellbore, comprises a fluid passage that allows flow of the fluid through the pulser, and a reciprocating member. A linear actuator is coupled to the reciprocating member, such that the linear actuator moves the reciprocating member in a first axial direction and then in a reverse direction to at least partially obstruct flow of the fluid through the pulser to generate pressure pulses in the flowing fluid.

摘要： An anti-plugging oscillating shear valve system for generating pressure fluctuations in a flowing drilling fluid comprising a stationary stator and an oscillating rotor, both with axial flow passages. The rotor oscillates in close proximity to the stator, at least partially blocking the flow through the stator and generating oscillating pressure pulses. The rotor passes through two zero speed positions during each cycle, facilitating rapid changes in signal phase, frequency, and/or amplitude facilitating enhanced data encoding. The rotor is driven by a electric motor disposed in a lubricant filled housing. In one embodiment, the housing to shaft seal is a flexible bellows. In one embodiment, a torsional spring is attached to the motor and the resulting spring mass system is designed to be near resonance at the desired pulse frequency. The torsion spring may be a solid torsion bar or a magnetic spring.

摘要： The present invention provides apparatus and method for drilling a wellbore wherein a pilot wellbore section is drilled with a bit which section is enlarged by a trailing underreamer to the desired size. One or more steering sections between the underreamer and the drill bit are utilized for maintaining and changing the drilling direction. Each steering section includes a plurality of independently adjustable force application devices on a non-rotating sleeve. If an expandable liner is used, then an expansion device disposed above the underreamer expands the liner during retrieval of the drilling assembly to the surface.
