Problems solved by technology

[0003] When the existing logging device guides the wellhead cable, the cable is guided deep through the pulley, and the cable swings, which increases the friction between the cable and the pulley, and the cable is exposed outside and its skin is easy to corrode and damage. The wellhead in the downhole is turned and it is not easy to adjust the direction of the cable guidance

Embodiment 1

[0023] See Figure 1 ~ 4 In the embodiment of the present invention, a wellhead port cable guide fixing means includes a mounting frame 1 and a fixed bracket 29, and the mounting frame 1 is mounted on the fixed bracket 29 and has two first cables on the mounting frame 1. Guide channel 2, each of the first cable guiding channel 2 is provided with a second cable guide channel 3 and the first cable guide channel 2 and the second cable guide passage 3 circular transition transition pass and passes through the hinge 6 is hinged, the second cable guide channel 3 is provided with a connecting post 30 and the first cable guide channel 2 is provided with an angle adjustment screw 7, and the angle adjustment rod 7 is provided with a helix cooperation with it. The angle adjustment screw 8 and the angular adjustment screw 8 side is slid in the side of the first cable guide channel 2 side wall, the angle adjustment screw 7 end through the bearing housing and the first cable guide channel 2 side...

Embodiment 2

[0031] See figure 1The embodiment of the present invention is different from that of the first embodiment in that the mounting frame 1 is provided with a bottom pallet 23 and a fixed bracket 29 is provided on the fixed bracket 29 and a vertical guide rod 26, the height. The lower end bolt is adjusted through the underside of the bottom plate 23 and rotate on the end surface of the fixed bottom plate 10, and the bottom end of the vertical guide 26 slides through the other bottom pallet 23 and fixed to the fixed bottom plate 10, said The height adjustment screw 24 is driven by a height adjustment motor 25 disposed at the top end of the fixed bracket 29; under the driving action of the high degree of adjustment motor 25, the height adjustment of the screw 24 rotates and utilizes the spiral cooperation with the bottom pallet 23 and the vertical guide rod. 26 The defined orientation can adjust the installation frame 1 and the first cable guide channel 2 height to adjust the wellhead to...

Abstract

The invention discloses a wellhead cable guiding and fixing device for well logging, which comprises a mounting frame and a fixing bracket, and is characterized in that the mounting frame is mounted on the fixing bracket and is provided with two first cable guiding channels; the bottom end of each first cable guiding channel is provided with a second cable guiding channel, the first cable guiding channels and the second cable guiding channels are in arc transition and are hinged through hinge seats, the side walls of the second cable guiding channels are provided with connecting columns, and the first cable guiding channels are provided with angle adjusting lead screws. The angle adjusting lead screws are provided with an angle adjusting screw sleeve, the side portion of the angle adjusting screw sleeve is in vertical sliding fit with the side wall of the first cable guiding channel, the side wall of the angle adjusting screw sleeve is provided with an adjusting push-pull rod with the top end hinged to the angle adjusting screw sleeve, and the bottom end of the adjusting push-pull rod is hinged to the connecting column. The device is simple in structure, plays a good role in protecting a cable from being guided into a logging well, facilitates adjustment of the guiding direction of the cable, and is high in practicability.

Description

Technical field [0001] The present invention relates to the technical field of logging devices, and is specifically a well-directed fixed device for logging wellhead. Background technique [0002] Logging, also known as geophysical logging, is a method of measuring geophysical parameters using geophysical characteristics, conductive properties, acoustic characteristics, radioactivity, and other geophysical properties, and measuring the physical parameters of geophysical parameters. In the oil drilling, the logging must be made after the depth of the design well, also known as completion of the electric measurement, to obtain various petroleum geological and engineering technical information, as the original information of the completion and development of oilfield, this log habit It is called a naked eye log. The second series of logging performed after the oil well is used, and it is commonly referred to as production logging or development logging. The development of production...
