    摘要: The invention relates to an improved filament-reinforced tubular, and a method for providing such a tubular. A filament-reinforced tubular according to the invention comprises a tubular body (2), the tubular body comprising multiple fibre mats (10) encapsulated in a thermoset material (11), and is at least at one end provided with a male screw thread (3) comprising threading. According to the invention, the threading comprises a core member (12, 16). Furthermore, the threading comprises one or more fibre mats (13) that cover the core member. The one or more fibre mats are pulled between the windings of the core member by a positioning wire (14). The core member, the one or more fibre mats, and the positioning wire, are encapsulated by a, preferably thermoset, cover material (15), which cover material defines the shape of the screw thread.

    摘要: The present invention relates to a top drive well drilling installation comprising a trolley guided along one or more vertical rails along the drilling tower, which trolley is provided with a support frame supporting the top drive unit and a rotating head-clamp. The rotating headclamp comprises an open-centered rotary body defining a pipe passage; a thrust bearing supporting the rotary body; and multiple mobile pipe retainers supported by the rotary body providing an operative and a non-operative position allowing passage of a pipe and engagement below a shoulder of a pipe of the drill string so as to suspend said drill string therefrom. At least the tubular stem is vertically movable relative to the rotating headclamp between an upper remote position allowing the engagement of a pipe of the drill string by the rotating headclamp and a lower connection position allowing the attachment of the tubular stem with the pipe.

    摘要: Moulding a composite pipe of fibre reinforcement material and a thermosetting resin that shrinks upon curing includes wrapping fibre reinforcement material about the tubular resilient sleeve of a mandrel in a non-expanded state of the sleeve. The mandrel includes an internal support structure for the sleeve which is reversibly expandable in diameter between the non-expanded state. The sleeve is internally supported by the internal support structure and an expanded state by application of an internal pressure to the sleeve. The mandrel with the fibre reinforcement material wrapped about the sleeve is accommodated in a bore of a mould. Seal members provide a closed annulus that can be evacuated. A thermosetting resin that shrinks upon curing is introduced into the closed annulus. A pressurizing fluid is supplied to the mandrel to internally pressurize the sleeve to cause diametrical expansion into the expanded state thereof whilst curing of the thermosetting resin.

    摘要: A riser section includes two filament-reinforced tubulars and a coupling sleeve for connecting the two filament-reinforced tubulars. The coupling sleeve includes a screw thread at opposite ends for cooperating with a screw thread provided on sections of the filament-reinforced tubulars. The riser section includes two torque locks, wherein the torque locks are each mounted on one of the filament-reinforced tubulars, and are on opposite ends of the coupling sleeve. The torque locks are provided with coupling teeth extending in an axial direction. The coupling sleeve is at opposite ends provided with coupling teeth extending in the axial direction. When the tubulars are screwed into the coupling sleeve and the torque locks have been mounted to secure the rotational movement of the tubulars relative to the coupling sleeve, the coupling teeth of each of the torque locks engages the coupling teeth of the coupling sleeve such that they block rotation of the torque lock relative to the coupling sleeve and allow for movement of the torque lock relative to the coupling sleeve in the axial direction, and thus allow for elongation of the sections of the tubulars including the screw thread. The pitch of the screw thread of the tubulars increases in a direction away from the end of the tubular, and the pitch of the screw threads of the coupling sleeve increases in a direction towards the end of the coupling sleeve.

    摘要: A method for servicing a top drive device of a wellbore drilling installation. The installation comprises a drilling tower, a drill floor having a well center through which a drilling tubulars string can pass along a firing line. A trolley is guided along a vertical trolley rail. A top drive device is attached to the trolley and comprises one or more top drive. A motion arm assembly comprises a base and an extensible and retractable motion arm, wherein the base is guided by a vertical motion arm rail. The motion arm has an operative reach that encompasses the firing line. The motion arm assembly is adapted to support at least one of a well center tool, e.g. an iron roughneck tool and a tubular gripper member, and allowing to bring said well center tool or tubular gripper member in the firing line. In order to remove a top drive motor from the top drive device whilst the rest of the top drive device remains attached to the trolley, the motion arm assembly and/or the trolley are operated so that the top drive motor is within the operative reach of the motion arm, the motion arm is operated to reach the top drive motor and the top drive motor is connected to the motion arm, and then the motion arm is used to support and/or lift, lower said top drive motor upon disconnection thereof from the rest of the top drive device.
