Abstract
The utility model discloses a cable perforation is with flexible aggravating device, including flexible nipple joint, lower clutch, the female joint of output, top connection, prevent changeing the screw, first aggravate and the second aggravates, wherein, the both ends of flexible nipple joint are connected respectively top connection and lower clutch, the female joint of output with the lower clutch is connected and with the sphere cooperation of flexible nipple joint set up on the top connection prevent changeing the screw, prevent changeing the one end of screw with flexible nipple joint contact, first aggravate with top connection, the second aggravate with the female articulate of output. The utility model discloses can realize that long distance aggravates flexonics, the section of deflecting is made through the horizontal well to the flexibility, can provide sufficient gravity for the operation of going into the well of cable, and the driving tube moves ahead in series, has alleviateed intensity of labour.
Description
Technical field
The utility model relates to a kind of disposable flexibility of implementing repeatedly perforating job of going into the well of cable perforation pipe string that is applicable to and increases the weight of device.
Background technology
The cable perforating job often needs supporting weighted lever can in straight well, horizontal well, move ahead to drive perforation pipe string, has overcome the limitation of oil gas well hole deviation degree.In the prior art, the cable perforation uses increases the weight of all to be rigidly connected, and is 200990490 like publication number, open day be on December 12nd, 2007 disclosed a kind of oil gas well with the device that increases the weight of of cable, comprise shell, conduct electricity plug, spring and movable contact stud; The endoporus of shell is divided into two sections, and the endoporus epimere has internal thread, and endoporus hypomere internal diameter is bigger, and the appearance hypomere has external screw thread; There is jack the upper end of conduction plug, and there is contact disc the lower end, and the conduction plug is contained in the endoporus epimere of shell, adorns insulating sleeve between the endoporus epimere of conduction plug and shell; Dress insulating cylinder in the endoporus hypomere of shell, movable contact stud is contained in the insulating cylinder, and spring is contained between the contact disc of movable contact stud and conduction plug, on the hypomere of the cased hole of insulation back-up ring.The utility model is applied to log well and being connected of the cable of perforating job.Beneficial effect is to guarantee that cable can be following smoothly in well, increases work efficiency.
But with above-mentioned patent documentation is the prior art of representative; In actual use; Increasing the weight of that the cable perforation uses all is to adopt to be rigidly connected; Length receives the hole deviation degree restriction of oil gas well shaft, and particularly horizontal well band voltage cable perforating job uses long rigidity weighted lever can increase labour intensity simultaneously.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of cable perforation and increase the weight of device with flexibility, it can realize that long distance increases the weight of to flexibly connect; Flexible through the horizontal well inclination section; Can be for well operations under the cable provide enough gravity, the driving tube string moves ahead, and has alleviated labour intensity.
The utility model is realized through adopting following technical proposals:
A kind of cable perforation increases the weight of device with flexibility; It is characterized in that: comprise that flexible pipe nipple, lower contact, output female joint, top connection, anti-turn screw, first increase the weight of and second increase the weight of; Wherein, the two ends of flexible pipe nipple connect said top connection and lower contact respectively, and the output female joint is connected with said lower contact and cooperates with the sphere of said flexible pipe nipple; Said anti-turn screw is set in said top connection; One end of anti-turn screw contacts with said flexible pipe nipple, and first increases the weight of to be connected with said top connection, and second increases the weight of to be connected with said output female joint.
Said first increases the weight of to be connected with fishing head.
Said second increases the weight of to be connected with the cable cap assembly.
Said anti-turn screw substitutes with anti-turn bolt./
Compared with prior art, the beneficial effect that the utility model reached is following:
The cable perforation increases the weight of to adopt the spherical structure design with flexibility, and promptly the two ends of flexible pipe nipple connect said top connection and lower contact respectively, and the output female joint is connected with said lower contact and cooperates with the sphere of said flexible pipe nipple; Said anti-turn screw is set in said top connection, and an end of anti-turn screw contacts with said flexible pipe nipple, and first increases the weight of to be connected with said top connection; Second increases the weight of to be connected with said output female joint, has overcome and has increased the weight of the technical problem that is rigidly connected, and realizes that long distance increases the weight of to flexibly connect; Flexible through the horizontal well inclination section; Can be for well operations under the cable provide enough gravity, the driving tube string moves ahead, and has alleviated labour intensity; Particularly export female joint and be connected with said lower contact and cooperate with the sphere of said flexible pipe nipple, increase the weight of to realize 360 degree rotations, also giving down, the well casing string provides big break-in angle; Said anti-turn screw is set in said top connection, can prevents effectively that flexible pipe nipple from moving back button.
Description of drawings
To combine Figure of description and embodiment that the utility model is done further to specify below, wherein:
Fig. 1 is the structural representation of the utility model
Mark among the figure:
1, first increases the weight of, and 2, anti-turn screw, 3, top connection, 4, flexible pipe nipple, 5, lower contact, 6, the output female joint, 7, second increases the weight of.
Embodiment
With reference to Figure of description 1, the utility model provides a kind of cable perforation to increase the weight of device with flexibility, the flexible pipe nipple lower contact 5 of packing into of flexible pipe nipple 4; Output female joint 6 is screwed into flexible pipe nipple lower contact 5, cooperates flexible pipe nipple 4 spheres; Increase the weight of 7 and be screwed into output female joint 6; Flexible pipe nipple 4 is screwed into flexible pipe nipple top connection 3; Anti-turn screw 2 is screwed into flexible top connection 3, and anti-flexible pipe nipple 4 moves back button; Increase the weight of 1 and be screwed in the flexible top connection 3, and tighten.
Penetrate cable in a whole set of flexibility increases the weight of, increase the weight of 1 and be connected, increase the weight of 7 and be connected with the cable cap assembly with fishing head.
The cable perforation increases the weight of and can flexibly connect well with flexibility; Realized that long adding reconnects the operation of going into the well; Also realize increasing the weight of to rotate in a circumferential direction, going into the well for cable perforation pipe string provides large driving force, has solved and has managed the technical barrier of ganging up high angle hole, horizontal well inclination section.
