Abstract
The invention relates to the field of oil field logging instruments, in particular to a connecting device between a logging cable and a horizontal well logging tool, and provides a novel torpedo for connection of the logging cable and a horizontal well butt-joint tool.
Description
Technical field
The present invention relates to the oil reservoir logging instrument field, specifically a kind of linkage between logging cable and the logging tool for horizontal wells is a kind of novel torpedo that logging cable is connected with the horizontal well engaging tool.
Background technology
At present, in the weighted lever that is widely used in the horizontal well engaging tool and the device that logging cable is connected, generally all can not make weakness, usually use special external conical sleeve, middle tapered sleeve, inner conical drogue fix to be contained in the torpedo behind the cable and are connected with weighted lever, tensile strength after the connection is identical with logging cable, have no idea to make comparatively desirable pulling-out force, and can only just can finish fitting operation by special tool, very inconvenient.
Summary of the invention
The present invention is in order to overcome the oil field at the weighted lever and the deficiency of logging cable in existence aspect being connected of logging tool for horizontal wells; a kind of weakness torpedo that can make desirable pulling-out force is provided; use this weakness torpedo; in the logging operation of application level well engaging tool; normally during unfreezing, pull at logging cable in case meet card, just can be implemented in weakness torpedo place to pull; thereby logging cable is pulled out well head, reached the purpose of protection logging cable.
The present invention is that the technical scheme that its technical problem of solution adopts is: logging cable passes the torpedo head, pass the torpedo shell, pass the torpedo main body, pass overcoat, pass inner sleeve, then the outer steel wire of choosing is walked around in the reverse simmering and bending insertion of the male cone (strobilus masculinus) aperture of inner sleeve, the cable core of logging cable is passed packing ring, pass the fluting block, put into the fluting endoporus of torpedo main body together with logging cable, at this moment at the first end pulling of torpedo logging cable, because the interaction of the inner conical surface of overcoat and the male cone (strobilus masculinus) of inner sleeve, can press the logging cable steel wire that inserts in the aperture after the simmering and bending of having chosen more tight, by compressing what of steel wire radical, can set the size of weakness pulling-out force, thereby realize that logging cable is connected with the vulnerable of torpedo.
The invention has the beneficial effects as follows: realize that logging cable is connected with the weighted lever of horizontal well engaging tool is vulnerable, realize easily, need not be by special tool when installation, dismounting, part is reusable, and is simple to operation.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is an axial section constructional drawing of the present invention
Fig. 2 is the A-A longitudinal sectional drawing of Fig. 1
1. torpedo heads among the figure, 2. torpedo shell, 3. overcoat, 4. jackscrew, 5. inner sleeve, 6. packing ring, 7. jackscrew, 8. fluting block, 9. torpedo main body, 10. connecting rod, 11. torpedo head endoporus, 12. main body endoporus, 13. the inner sleeve aperture, 14. male cone (strobilus masculinus)s, 15. inner conical surfaces, 16, fluting endoporus
The specific embodiment
In Fig. 1, torpedo head 1 is threaded connection with torpedo main body 9, and the center of torpedo head 1 is drilled with torpedo head endoporus 11, sleeve 2 is enclosed within on the torpedo main body 9, and torpedo main body 9 centers are drilled with main body endoporus 12, and is provided with fluting endoporus 16, at the fluting overcoat 3 of packing into successively in the endoporus 16, inner sleeve 5, packing ring 6, fluting block 8, it is fixing to apply mechanically two jackscrews 4 outward, two jackscrews of fluting block 8 usefulness 7 are fixing, are connected by the weighted lever of connecting rod 10 with the horizontal well engaging tool at last, totally become cylindric.
Claims (3)
1. weakness torpedo, logging cable passes the torpedo head, pass the torpedo shell, pass the torpedo main body, pass overcoat, pass inner sleeve, then the outer steel wire of choosing is walked around in the reverse simmering and bending insertion of the male cone (strobilus masculinus) aperture of inner sleeve, the cable core of logging cable is passed packing ring, pass the fluting block, put into the fluting endoporus of torpedo main body together with logging cable, it is characterized in that: the reverse simmering and bending of male cone (strobilus masculinus) of the outer steel wire of choosing being walked around inner sleeve are inserted in the aperture, the cable core of logging cable is passed packing ring, pass the fluting block, put into the fluting endoporus of torpedo main body together with logging cable.
2. a kind of sealed insulation according to claim 1 mechanism, it is characterized in that: logging cable passes successively the torpedo head, passes the torpedo shell, passes the torpedo main body, passes overcoat, passes inner sleeve, is placed on together in the fluting endoporus of torpedo main body.
3. a kind of sealed insulation according to claim 1 mechanism, it is characterized in that: by the inner conical surface of overcoat and the male cone (strobilus masculinus) of inner sleeve, press the logging cable steel wire that inserts in the aperture after the simmering and bending of having chosen more tight, according to compressing what of steel wire radical, can set the size of weakness pulling-out force, thereby realize that logging cable is connected with the vulnerable of torpedo.
