Continuous oil pipe logging auxiliary treatment device and method

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...

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
