摘要： A connector for connection of a pipe end portion of coiled tubing adapted for connecting a piece of downhole equipment. The connector is formed by three separate parts that can be screwed together two and two, of which a radially inner shrinkable adapter sleeve compressively surrounded by an elongate outer adapter and connector sleeve ensures the securing of the end portion of the coiled tubing, whereas a freely projecting, internally threaded end portion of the outer sleeve ensures the connection to the remaining part of the connector in the screwing together. The connector, besides exhibiting improved tensile, flexural and compressive strength properties, is also well suited to absorb torques applied. The inner shrinkable adapter sleeve, which has an external jacket surface of an axially conical extent, is provided with external threads, complementarily matched by the internal threads of the outer adapter and connector sleeve, which are formed in the bore-defining inner circumferential surface, which has a conical extent in the axial direction, its conicity complementarily corresponding to the externally conical extent of the inner adapter sleeve.

摘要： A tool adapted for changing the direction of drilling during drilling. The drilling equipment used in the drilling includes a drill string, a bent sub, a drill motor, and a drill bit. The tool is positioned between the drill string and the bent sub, includes housing elements connected to one another, and has a passage for drilling fluid. The tool can be activated for rotation of the bent sub, so that the direction of drilling is changed in an infinitely variable manner. The tool includes a valve adapted for choking the passage so that the tool can be activated for rotation, a piston adapted for forced guiding of the rotation. The guides can be formed by twisted splines formed in the wall of the passage and in the wall of the opposite piston.

摘要： A hydraulic impact tool for use in a well, such as an oil or gas well, comprising a movable hammer which is arranged to prestress a spring by means of a hydraulic piston (16) provided with a through channel (20), and in which a movable sealing body (22, 45) is arranged to enable closing of the channel (43), so that hydraulic force from fluid under pressure applied to the impact tool, may displace the piston (16) and the hammer and prestress the spring, and in which the sealing body (22) is arranged to follow the piston (16) into an end position for so to open the channel (20) for throughput, so that the hydraulic force acting on the piston (16, 41) ceases, and the prestressed spring is released and drives the hammer to strike, at the same time as the piston (16, 41) returns to initial piston, whereafter the process is repeated. The sealing body (22) is arranged to close said channel (20) when the sealing body is subjected to a predetemined frictional force from fluid flowing through the impact tool.

摘要： A hydraulically releasable coupling device has an upstream part arranged to permit connection to tubing and a downstream part arranged to be connected to a tool or equipment. A radially expandable locking ring is configured to expand and thereby to disconnect the coupling device. A movable securing ring portion encloses the locking ring at least partially in an unexpanded locking position thereof. A piston body is connected to the securing ring portion and has a through passage which is provided downstream with a restriction element. The piston body has an upstream piston head with an annular upstream reaction surface and an annular downstream reaction surface for pressure fluid in counterflow. The piston head has a larger diameter than a downstream extension formed as a piston skirt, in which the restriction element is mounted. A longitudinal portion of the piston skirt, next to the piston head, is enclosed by a cylinder chamber of the piston head accommodating a return spring.

摘要： A gripper mechanism (22) suspended in a coiled tubing/wireline in a well serves to releasably hold a downhole tool or other piece of equipment positioned downstream, via a tubular connecting element (10). The gripper mechanism (12) comprises axially, two relative to each other, movable coaxial parts (18, 16), a gripping part (18) designed to grip said connecting element (10) and an actuating part (16) designed to exert a radial clamping effect on the gripping portion (18a) of the gripping part (18) when this is in engagement with said connecting element (10). The clamping effect is due to complimentary conical face on opposite sides of the two parts (16, 18) of the gripper mechanism (12) being forced against each other by the axial displacement of one part (16) relative to the other part (18) in one direction (the upstream/pull-up direction). In order to enable a small cone/coning angle to be used at these complimentary conical faces, while at the same time ensuring that the conical faces do not get wedged to each other across a longitudinal course in the axial direction, the conical faces of each part (18 and 16) have been divided, so that each conical face comprises annular conical part faces (32, 28) and intermediate annular cylindrical part faces (34, 30). The conical part faces (32, 28) have a mutually equal amount of taper and the same axial extent. The intermediate cylindrical part faces (34, 30) have a mutually equal axial extent.

摘要： An arrangement by a hydraulic jar device, especially for use in underground wells, where the jar device is installed in a pipe string led down into the well, and designed so that e.g. a stuck object in the well may be loosened or broken up by upward or downward percussions from the jar device. The jar device is actuated by increasing the flow of drill fluid. Alternatively, the device is actuated by compression. A valve (27, 37, 38) closes off the flow of drill fluid, whereby a percussion cycle is initiated. The valve is designed so as also to seal during strong lateral accelerations.
