Abstract: The invention relates to a device by a tool (1) adapted for changing the direction of drilling during drilling. The drilling equipment used in the drilling preferably comprises a drill string such as coiled tubing, a bent sub, drilling motor and drill bit. The tool (1) is positioned between the drill string and the bent sub, comprises housing elements (2-5) connected to one another, and has a passage for, i.a., fluid such as drilling fluid. The tool can be activated for rotation of the bent sub, so that the direction of drilling is changed. The object of the invention is to provide a tool, whereby the rotation of the bent sub can take place in an infinitely variable manner. This is realised by means of means (18, 20-24, 26, 27) positioned in the passage of the tool (1), and comprising a valve (20-24) adapted for choking the passage, so that the tool (1) can be activated for rotation, a piston (18) adapted for providing the rotation after the passage has been choked, and sets of co-operating guides (26, 27) adapted for forced guiding of the rotation. The guides (26, 27) can be formed by twisted splines formed in the wall of the passage and in the wall of the piston (18) opposite.

Abstract: An adjustable bend connection is provided which desirably extends from the power section (22) of a downhole progressing-cavity-type mud motor. The joint is secured internally so that any reverse rotation of the bend housing that may occur does not result in the undoing of the bend connection. Torque is transmitted separately from the portion of the connection which is used to secure the angle selected. The output shaft (20) from the mud motor extends internally through the bend connection and through the components which retain the preselected angle. A tool (T) can be inserted with the bit (10) removed to secure or change the angle desired.

Abstract: A drill bit (6) is equipped with one or more fluid jets (7) that are activated during a portion of the rotational movement of the drill bit (6). A processor (41) located with other down-hole sensors (33-38), is programmed with parameters defining the desired path of the borehole (8). The sensors (33-38) determine the actual spatial location of the drill bit (6) and provide the processor (41) with corresponding information. The processor (41) compares the actual drilling path to the desired path, and if a correction is required, a switching module (3) allows a pressurized drill fluid to be sequentially switched to selected jets (7) during rotation of the drill bit (6) to thereby erode the formation in a direction toward the desired path. With this arrangement, the problems of directional control by surface-located equipment are overcome.

Abstract: A drill string orienting tool (10) for insertion into a well bore (12) includes a housing (22) that has a plurality of inwardly projecting splines. A mandrel (32) is disposed within the housing (22). The orienting tool (10) has two operating positions, a running position, and an orienting position. The housing (22) is longitudinally moveable relative to the mandrel (32) between the running position and the orienting position. The mandrel (32) and the housing (22) define an annular chamber (38) that is vented to the exterior of the housing. A flexible metallic coiled tube (36) is disposed within the annular chamber (38) and contains hydraulic fluid. The upper end of the coiled tube (36) is coupled to the housing (22) and is in fluid communication with the first fluid chamber (104). The lower end of the coiled tube is coupled to the mandrel (32). The mandrel (32) has outwardly projecting splines (128) that are engageable with a corresponding set of inwardly projecting splines on the housing (22) when the orienting tool is in the running position. A piston (90) is movably disposed within the housing (22). The piston (90) and the housing (22) define a first fluid chamber (104), and a second fluid chamber (109). The second fluid chamber is vented (110) to the exterior of the housing (22). Downward movement of the piston causes a positive pressure differential between the pressure inside the coiled tube (36) and the pressure outside the coiled tube (38), thereby causing the coiled tube to uncoil and rotate the mandrel (32) relative to the housing (22).

Abstract: A variable angle directional drilling "sub" provides a shifting end portion which allows the sub to be rotated from a first, in-line, axially straight orientation with the drill string to a selected second, angled or "bent" position. The tool (10) provides a multiple choice of varying angles to the sub in its bent position to satisfy differing directional drilling situations. A first embodiment (Figs. 1-7) is manually set and varied at the surface by positioning two angularly marked section (70, 71) temporarily rotatable with respect to each other until the desired angle set is matched up, while a second embodiment (Figs. 8-9) is motor driven to allow varying the angle direction while "down in the hole". The device rotatably shifts about an off-set axis of rotation of sleeve (20) with axis (40a) of movable connection (40) from the first (in-line) position aligned with axis (12a) of barrel (12) to the second (bent) position with these axes misaligned either (in the first manually adjustable embodiment) upon the application of torsional force thereto, which torsional force can be applied, for example, by the actuation of a "turbodrill" (102) (normally attached in operation), or (in the second motorized embodiment) by an electrical signal from the surface to a built-in motor contained within the tool.
