摘要： A drilling system for boring into ground includes a bottom hole assembly having a rotatable casing shoe, an independently rotatable driveshaft disposed within the casing shoe, and a bearing housing interdisposed between the driveshaft and the casing shoe to control a distance between a centerline of the driveshaft and a centerline of the casing shoe. The driveshaft includes a bit disposed at a distal end thereof, extending beyond the casing shoe distal end. The driveshaft centerline and the casing shoe centerline are substantially parallel and radially offset.

摘要： Multiple section mills are run in a single trip with an intervening mill preferably a watermelon mill to grind up any cuttings that get past the first mill in a direction toward the second mill below it. The blades of the second mill are held by the innermost tubular until the location of the initial cut is reached at which point the longer arms of the second mill can be extended and its body centralizes due to the flexibility of the connection between the mills.

摘要： A liner drilling system employs a bottom hole assembly that may be retrieved before reaching the total liner depth. The system includes an outer string made up of a liner and a profile nipple. An inner string including a running tool, drill pipe, and a drill lock tool are lowered into the outer string and rotationally and axially locked to the outer string. Drilling may be performed by rotating the inner string, which also rotates the outer string. The operator may retrieve the inner string by pulling the inner string and the liner upward until the upper end of the liner is located at the drilling rig floor. While supporting the liner at the drilling rig floor, the operator retrieves the inner string, then re-runs it back into the outer string.

摘要： An underreamer drill bit assembly including a pilot bit (82) and extendable underreaming arms (88) operatively connected to the pilot bit (82). The underreaming arms (88) have an extended position for underreaming, and a retracted position in which the overall diameter of the underreamer drill bit assembly is less than the inside diameter of the well casing, permitting the entire bit assembly to be withdrawn through the well casing. In another aspect of the invention, the bit assembly is operatively connected to a dual wall pipe assembly (12). A supply of compressed air is conducted through the annulus (24) of the dual wall pipe assembly (12) to a down hole pneumatic hammer (13). Exhaust air from the down hole hammer (13) is directed to the bit assembly for continuous removal of drilling debris through a central evacuation tube (43) of the dual wall pipe assembly.

摘要： A downhole impact drill having a drill bit head (14) with a drill bit sector (42) for drilling an enlarged hole upon rotation of the drill. The bit is mounted within a chuck (24) for movement between a retracted, working position in which the bit is coaxially mounted for drilling and an extended, non-working position in which the bit is loosely mounted within the chuck (24) to permit the bit to swing laterally to reduce the diameter of the drill bit head envelope. In its extended, non-working position, the bit is supported on the chuck (24) at a 3° angle at which the drill bit sector is positioned inwardly to facilitate installation and withdrawal of the drill.

摘要： A bottom hole assembly in a casing-while-dr tiling operation is retrieved by displacing the fluid in the casing string with a less dense fluid than the fluid in the annulus. The bottom hole assembly moves upward in the casing string in response to an upward force due to the different densities of fluid in the casing string and in the annulus. Displaced fluid flows out of the casing string and through a restrictive orifice of a choke. The flow area of the orifice is varied as the bottom hole assembly moves upward to control the rate at which the bottom hole assembly moves upward.

摘要： A method and apparatus for conducting earth borehole operations including a reel of continuous coiled casing, and an injector for moving the coiled casing. The bottomhole assembly including at least a motor and a bit connected to the free end of the coiled casing, and injected into the earth while circulating fluid through the coiled casing to form a drilled earth borehole having a borehole wall. The coiled casing drill string may be retrieved from the borehole, the bottomhole assembly removed, and the coiled casing again injected into the borehole, then suspended from a wellhead assembly. After severing the coiled casing, a bonding agent such as a cementitious material may be injected into the suspended coiled casing and into the annulus between the coiled casing and the borehole.

摘要： A retractable drill bit system (10) typically for oil and gas drilling. The system (10) includes drill bit assembly (14) engageable with a drive sub (12) attached to the end of a drill string. Drill bit assembly (14) includes fingers (80) that can expand and collapse between a transport position and a cutting position. The drill bit assembly (14) is carried on a bit assembly sleeve (16). Transport member (18) extends inside the sleeve (16) and is resiliently coupled thereto so that the sleeve (16 and 18) can slide relative to each other. Relative sliding motion of member (18) and sleeve (16) in one direction expands the fingers (80) to the cutting position where relative sliding motion in the opposite direction collapses the fingers (18) to the transport position. This motion allows the system (10) to cut a hole of substantially greater diameter than the diameter of the drill string to which the drive sub (12) is attached.
