An upper connector is arranged to be a whole, a sealing assembly is arranged at the bottom of the upper connector, the sealing performance is improved, and the high-temperature resistance is improved. Compared with the prior art, the high-temperature rotating pup joint logger assembly has the advantages that two ends of the rotating pup joint can rotate relatively, meanwhile, connection of electric appliance signals is guaranteed, in the process that the instruments are plated into the bottom of a well, the torsion transmitted to the downhole instrument by the cable can be released through the rotating pup joint, measurement error and instrument damage, which are caused by rotation, of the other instruments are effectively avoided, the service life of the logging instruments is prolonged, and the logging reliability is improved.
Description
Technical field
The utility model relates to well logging supplementary instrument field, relates in particular to a kind of High Temperature Rotating pipe nipple logging instrument assembly.
Background technology
Oil well logging instrument generally comprises ground logging system and downhole instrument two parts, connect this two parts by logging cable, the effect of cable is logger to be put into down-hole or carrying and logging well on instrument, and uploads the signal that downhole instrument collects and pass down the instruction that ground system sends.In practical logging process, combined instrument well logging is more, cable load-bearing is larger, and cable also needs to overcome the torsion of self simultaneously, and instrument is delegated to down-hole or elevates, because logger string bottom is unsettled, therefore rotate, in the situation that not rotating short circuit, the torsion of instrument string rotation will be delivered on cable, even, to twisting off cable, cause major accident.At present, the well temperature that existing rotation short circuit can bear is 150 DEG C, and because logging environment is more and more severe, in the time that downhole temperature reaches 175 DEG C, cable transmission signal will be affected, and common logging instrument top connection is all that separate groups is box-like, and sealing effectiveness is bad.
Summary of the invention
The purpose of this utility model is to provide a kind of High Temperature Rotating pipe nipple logging instrument assembly, by static seal short circuit being set and movable sealing short circuit ensures the reliability of logging well, pass to the torsion of downhole probe by rotation short circuit releasable cable, and guaranteeing that instrument connection of thread is unlikely gets loose, realize in instrument string between adjacent apparatuses rotation mutually or discharged the function of the moment of torsion that instrument string produces.Be set to whole one by top connection, and in bottom, black box be set, improve instrument sealing performance and resistance to elevated temperatures.
For achieving the above object, the utility model is realized by the following technical solutions:
A kind of High Temperature Rotating pipe nipple logging instrument assembly, comprise helmet, top connection, rotating short-knot, central axis, locking nut, piston urceolus, lower contact, thread protector, core public plug, core mother socket, sealing-plug assembly, described rotating short-knot comprises slip ring overcoat, slip ring shift fork, core slip ring assembly, movable sealing short circuit, static seal short circuit, helmet is arranged in top connection, and slip ring is set on top connection bottom outward; Described top connection is set to one with the sealing cock body that sealing-plug assembly is installed, slip ring shift fork is arranged on lower contact bottom, core slip ring assembly is fixed in top connection by slip ring shift fork, core slip ring assembly lower end is connected with central axis and is arranged on slip ring overcoat inside, movable sealing pipe nipple is connected with slip ring overcoat by screw thread, static seal pipe nipple is connected with piston urceolus by screw thread, locking nut is arranged on central axis bottom, piston urceolus is connected by central axis with slip ring overcoat, lower contact is connected with piston urceolus bottom, and thread protector is arranged on lower contact bottom; Described core mother socket is arranged in top connection, and core public plug is arranged in lower contact.
Compared with prior art, the beneficial effects of the utility model are:
Rotating short-knot two ends can relatively rotate, ensure again the perforation of electrical signal simultaneously, especially with hydraulic thrust by wait combined instrument string in there is especially important function, instrument is transferred in bottom process, releasable cable passes to the torsion of downhole probe, and guaranteeing that instrument connection of thread is unlikely gets loose, realize the function of mutually rotating or discharge the moment of torsion of instrument string generation in instrument string between adjacent apparatuses, other instruments are effectively avoided, because rotating the measure error and the instrument damage that cause, extend the physical life of logger, improve the reliability of well logging.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is further illustrated:
As shown in Fig. 1～Fig. 5, a kind of High Temperature Rotating pipe nipple logging instrument assembly, by helmet 1, top connection 2, rotating short-knot, central axis 6, locking nut 9, piston urceolus 10, lower contact 11, thread protector 12, core public plug 14, core female 13 forms, and described rotating short-knot comprises slip ring overcoat 3, slip ring shift fork 4, core slip ring assembly 5, movable sealing short circuit 7, static seal short circuit 8, helmet 1 is arranged in top connection 2, slip ring overcoat 3 is arranged on top connection 2 bottoms, described top connection 2 is set to one with the sealing cock body that sealing-plug assembly 15 is installed, slip ring shift fork 4 is arranged on lower contact 11 bottoms, core slip ring assembly 5 is fixed in top connection 2 by slip ring shift fork 4, core slip ring assembly 5 lower ends are connected with central axis 6 and are arranged on slip ring overcoat 3 inside, movable sealing pipe nipple 7 is connected with slip ring overcoat by screw thread, static seal pipe nipple 8 is connected with piston urceolus 10 by screw thread, locking nut 9 is arranged on central axis 6 bottoms, piston urceolus 10 is connected by central axis 6 with slip ring overcoat 3, lower contact 11 is connected with piston urceolus 10 bottoms, and thread protector 12 is arranged on lower contact 11 bottoms, described core female 13 is arranged in top connection, and core public plug 14 is arranged in lower contact 11.
When work, installation bearing ensures the rotation of instrument internal, and static seal short circuit 8 is connected with slip ring overcoat 3 by screw thread, and movable sealing short circuit 7 is connected with piston urceolus 10 by screw thread.Instrument lower end, by screw protective screw, ensures in practical logging work the HTHP of down-hole and H
2s has a strong impact on the sealing of instrument, therefore not only requires instrument self rotation to meet logging requirements, and seals in rotation.Top connection is set to integrative-structure with the sealing cock body that sealing-plug assembly position is installed, and in bottom, black box is set, and improves sealing, and has improved resistance to elevated temperatures.
From instrument upper end core mother socket 13 to lower end core public plug 14, circuit connection connects, the circuit of instrument top and bottom is realized and being connected and rotation by core slip ring assembly, it is the tie of equipment circuit and machinery rotation, in the time that rotation relatively occurs cable box instrument string, just can ensure the rotation of instrument itself and the connection of instrument by slip ring.
