    摘要： A deflector assembly includes two deflectors that can cooperate for directing a bullnose assembly toward an intended bore in a multi-bore well based on a configuration of the bullnose assembly without requiring use of gravitational forces or requiring the assembly to be oriented in a certain manner. The deflectors can cooperate by being spaced by a certain amount that, depending on if the amount is less than or greater than a longitudinal length and diameter of a bullnose of the bullnose assembly, can allow the bullnose assembly to be diverted toward the intended bore.

    摘要： A fulcrum bearing assembly for rotatably supporting a shaft within a housing, including at least one row of spherical thrust bearings positioned at a first axial position within the housing, at least one row of spherical thrust bearings positioned at a second axial position within the housing and at least one row of spherical radial bearings positioned at a third axial position within the housing. The third axial position is located between the first and second axial positions. Further, a bearing preload assembly for maintaining a bearing assembly in a preloaded condition, including a thrust bearing shoulder associated with a housing and a thrust bearing collar. The bearing assembly is axially maintained within the housing between the thrust bearing shoulder and the thrust bearing collar, wherein the thrust bearing collar is axially adjustable relative to the thrust bearing shoulder in order to preload the bearing assembly therebetween.

    摘要： Adjustable drill string housings are described for use in the directional drilling of wellbores, e.g. wellbores for hydrocarbon recovery wells. The adjustable drill string housings permit adjustment of a bend angle in the housings without removing the housings from a wellbore. In some exemplary embodiments, the bend angle can be adjusted by changing the internal stresses in a support member carried by the housings. In other embodiments, the bend angle may be adjusted by causing failure of sacrificial support members carried by the housings, and the failure may be caused by delivering chemicals through a chemical delivery system to the sacrificial support members. Methods of operating the adjustable drill string housings include multi-lateral drilling operations wherein the bend angle is adjusted when a casing window has been detected.

    摘要： A method includes conveying a whipstock and a latch anchor into a parent wellbore, the latch anchor being attached to the whipstock at a releasable connection and the parent wellbore being lined with casing that includes a latch coupling. The latch anchor is secured to the latch coupling and the whipstock is then separated from the latch anchor at the releasable connection and thereby exposing a portion of the releasable connection. The whipstock is then removed from the parent wellbore and a completion deflector is subsequently conveyed into the parent wellbore in combination with lateral tubing (with or without a multilateral junction positioned thereabove), and the completion deflector is attached to the latch coupling at the releasable connection. The lateral tubing (with or without multilateral junction positioned thereabove) is then installed to correct depth.

    摘要： A system and method for milling a casing in a wellbore wherein an upper milling portion of a milling system engages a track of a lower guide system of the milling system in order to orient the upper milling portion. The upper milling portion moves along a track from a first position to a second position, where the the upper milling portion is securedly affixed to the lower guide portion. A traveling guide arm is used to move the milling portion along a travel path. A piston on the traveling guide arm is disposed between first and second fluid chambers, with a throughbore in the piston forming a fluid path between the two chambers. An adjustable valve in the throughbore is controlled by a proximity sensor to alter the flow of fluid between the chambers. The sensor monitors the distance between a fixed and moving point of the milling system.

    摘要： A drilling module is for radial drilling in a well and an anchoring module is for use in a well tool. The drilling module has a piston for receiving a drill for the radial drilling, and for displacing the drill in a radial direction towards a wall of the well and a cylinder for receiving and guiding the piston. Both the piston and the cylinder are guide-free and of a non-circular shape, at least in a portion, to prevent relative rotation between them. The anchoring module has an extent in the axial direction of the well. The anchoring module includes a displacement device arranged to push against a portion of the wall of the well to press the anchoring module against an opposite portion of the wall of the well. The displacement device is oblong in the axial direction of the anchoring module.
