摘要： The present invention relates to a system and method for automated or “robotic” application of hardfacing to the surface of a steel-toothed cutter of a standard earth-boring rock bit or a hybrid-type rock bit. In particular, the system incorporates a grounded adapter plate and chuck mounted to a robotic arm for grasping and manipulating a rock bit cutter, particularly a hybrid rock bit cutter, beneath an electrical or photonic energy welding source, such as a plasma arc welding torch manipulated by a positioner. In this configuration, the torch is positioned substantially vertically and oscillated along a horizontal axis as the cutter is manipulated relative along a target path for the distribution of hardfacing. Moving the cutter beneath the torch allows more areas of more teeth to be overlayed, and allows superior placement for operational feedback, such as automatic positioning and parameter correction. In the preferred embodiment, sensors provide data to the control system for identification, positioning, welding program selection, and welding program correction. The control system, aided by data from the sensors, manipulates the robotically held cutter while controlling the operation and oscillation of the torch. These systems and methods can be applied to hardfacing steel teeth of the rolling cutters of both standard tri-cone or di-cone type rolling cone bits, as well as to hybrid-type earth boring drill bits.

摘要： An apparatus for use downhole is disclosed. The apparatus includes a downhole device and an actuation device that includes: a housing including an annular chamber configured to house a first fluid therein and a piston in the annular chamber that divides the annular chamber into a first section and a second section. The piston is to a biasing member. A control unit enables movement of the first fluid from the first section to the second section to supply a second fluid under pressure to the tool to move the tool into an active position and from the second section to the first section to stop the supply of the second fluid to the tool to cause the tool to move into an inactive position.

摘要： Walk characteristics of an earth-boring rotary drill bit may be predicted by measuring locations and orientations of cutting elements thereof and calculating the magnitude and direction of an imbalance force of the drill bit using the measurements obtained. The calculated imbalance force may be compared to the imbalance force of at least one other drill bit having a calculated imbalance force and observed walk characteristics. An earth-boring rotary drill bit may be designed by constructing a database including the magnitude and direction of a calculated imbalance force and observed walk characteristics for a number of drill bits. Desired walk characteristics are selected, the database is referenced, and the bit may be configured to exhibit an imbalance force selected to impart desired walk characteristics to the drill bit. Drill bits are configured to exhibit an imbalance force oriented in a predetermined direction relative to a blade of the drill bit. A system may be employed to monitor the imbalance force of an operating drill bit and to provide or implement desirable operational parameters to compensate for same.
