Title: Elevating operator cabin for coiled tubing injector
Inventor: MCCULLOCH DAVID W
IPC: B62D33/063
Filed: 2004-05-05
Abstract: A transportable, elevating operator cabin for use in connection with controlling coiled tubing injection equipment comprises a cabin including control elements; an elongated flexible element of fixed length extending under the cabin, between two, elevated points on adjacent structures located on opposite sides of the cabin; and a take-up mechanism for shortening the length of the flexible element between the two, elevated points. The take-up mechanism is mounted in a fixed position relative to the cabin so that operation of the take-up mechanism results in elevating of the cabin with respect to the adjacent structures. The cabin may be raised to a distance roughly equal to the height of the cabin while maintaining a compact design not much larger than the cabin itself that is suitable for transport, and the arrangement avoids mechanical complexity and costs associated with using other types of lifting mechanisms.

Abstract: The invention relates to a method of correlating two or more overlapping well logs generated by a well logging device which, in use, is positioned in a well and is mounted to an elongate member extending along the well to the surface, movement of the elongate member at the surface controlling movement of the logging device along the well. The method comprises: (a) receiving sets of logging data for two or more spatially overlapping logs generated by the logging device, each set comprising measures of a characteristic of the well at longitudinally spaced positions along the well; (b) receiving measurement data for the period or periods of log generation, the measurement data comprising measurements of the load on the elongate member and measurements of the surface position of the elongate member; and (c) correlating the sets of logging data by determining an elongate member compliance which corrects the positions of the measured well characteristics. The corrections in step (c) are performed on the basis of a correction function which relates the position of the logging device to at least (i) the measured load on the elongate member, (ii) the measured surface position of the elongate member, and (iii) the compliance of the elongate member.

Patent CA-2483932-A1 (CA)
Inventor: SATO MICHIO
IPC: B23P21/00
Filed: 2004-10-04
Abstract: It is an object of the invention to provide a removing method of a TUBE in which it is possible to easily pull out and remove, within a short time, the TUBE which is inserted into a tube-hole having an annular groove in its inner circumference of the tube-sheet and which is increased in diameter and fixed thereto. In removing a TUBE 3 increased in diameter and fixed to a tube-sheet 1, an inserted portion 3a which is fixed to a tube-hole 2 of the tube-sheet 1 is heated and then cooled, thereby reducing its diameter, and the inserted portion 3a is loosened from the tube-hole 2. Then, a region 3h opposed to a groove 4 formed in an inner circumference of the tube-hole is heated to a red-hot state, and the TUBE 3 is stretched in its axial direction, the red-heated region 3h is stretched to reduce its diameter and cut the region 3h, thereby pulling out the TUBE 3 from the tube-sheet 1.
