Problems solved by technology

[0003] The purpose of the present invention is to provide a coiled tubing logging auxiliary processing device and method for the above-mentioned defects in the prior art. Due to the split design, the production is simpler and more reliable, and the whole has no welding parts, avoiding the electronic The heating of the components increases the fixing of the electronic components at the same time, making the use of electronic components more firm and reliable; the length is also greatly shortened, avoiding the problem of disconnection of the weld in the inclined shaft

Embodiment 1

[0034] Embodiment 1, with reference to attached figure 1 , a kind of coiled tubing logging auxiliary treatment device mentioned in the present invention, its technical scheme is: including sealing PTFE protection pad 3, transition joint 4, sealing rubber ring 5, opening support ring 6, sealing protection sleeve 7, test tube 8. Guide shoe 9, test terminal 10, seat sealer 13, lock spring 14, cone 15, sealing rubber cylinder 16, liner 17, setting seal interference rubber ring 18, and the inner cavity of coiled tubing 2 is worn with Test cable 1, at the end of coiled tubing 2, seat sealer 13, lock spring 14, cone 15, sealing rubber tube 16 and liner 17 are installed in the cavity between coiled tubing 2 and test cable 1, The setting device 13 is connected to the lower end of the liner 17, then, refer to the attached figure 2 , align the seat sealer 13 with the seat seal wrench 20 and rotate, the liner 17 moves down, and the lock spring 14 drives the cone 15 to move up, and the e...

Embodiment 2

[0052] Embodiment 2, a coiled tubing logging auxiliary processing device and method mentioned in the present invention, differs from Embodiment 1 in that: the cone and the lock spring are removed, and the seat sealer is changed to have ring teeth on the outer wall. The inner side is threaded with the lower end of the liner, and the ring teeth on the outer wall are fixed and supported by the coiled tubing. In this way, through the rotation of the special wrench for the seat seal, the upper surface of the seat seal is in contact with the sealing rubber cylinder 16 and squeezed The sealing rubber cylinder 16 makes it expand, thereby also realizing the long seal between the coiled tubing and the test cable.

Abstract

The invention relates to a continuous oil pipe logging auxiliary treatment device and method. A setting device is connected to the lower end of a lining pipe, a setting wrench is aligned with the setting device for rotation, the lining pipe moves downwards, a lock spring drives a cone body to move upwards, a seal rubber cylinder is extruded to expand to achieve seal, the lower end of a seal tetrafluorohydrazine protection pad connected with a continuous oil pipe is connected with a transition joint, the lower portion of the transition joint is provided with a seal rubber ring and an opening supporting ring, a seal protection sleeve is movably connected with the transition joint through the opening supporting ring, the tail end of a test cable carries out connection on a test tube throughconnection with a test wiring head, and the lower end of the test tube is provided with a guiding shoe. The device has the beneficial effects that due to split design, manufacturing is easy and reliable, no welding exists, heating of an electronic element is avoided, meanwhile, fixing of the electronic element is added, use of the electronic element is firmer and more reliable, and compared with an original direct abut-welding process, the breakage phenomenon due to a fragile and rigid welding opening can be overcome.

Description

technical field [0001] The invention relates to a coiled tubing logging auxiliary processing device and method, in particular to a coiled tubing logging auxiliary processing device and method. Background technique [0002] In the coiled tubing logging process, generally the logging joint is directly welded to the end of the coiled tubing, and then the testing instrument is connected and run downhole, but there is a problem that the measuring electronic Therefore, in welding, temperature control is a very important technical parameter, and this parameter has a specific numerical control method under the current technical conditions. At the same time, after the welding temperature is limited, the welding quality will be improved. It will be greatly affected; therefore, in actual operation, due to the fear of damage to electronic components during welding, the usual method is to lengthen the transition section, which creates a new problem: in a deviated well, if the well deviat...
