Description
Technical field
The utility model relates to oilfield horizontal well logging technique field, is specifically related to a kind of horizontal wellbore logging safety cable head.
Background technology
At present, in deep-well is surveyed, particularly in the oil well logging, the steel wire cable head has two kinds with the connected mode of downhole instrument: a kind of is directly to be connected with downhole instrument, during well logging, because the tension force of steel wire, to drive downhole instrument and rotate, thereby influence log parameter in the down-hole; The rotatable cable adapter of another kind of employing connects, and during well logging, because downhole instrument does not rotate, steel wire cable rotates, thereby reduces the influence of instrument rotation to log parameter.Because subsurface environment is abominable, pressure, temperature are higher, and this electric and mechanical performance to cable head all has strict requirement.
Chinese patent notification number: CN201851028U, a kind of " being used for the cable head that logging cable is connected with downhole instrument " is provided, relate to the cable connector technical field, comprise the stayed mast unit, with the tool interface system unit that is connected stayed mast unit one end, the stayed mast unit other end is connected with the fishing head unit, described fishing head unit comprises fishing head, quick torpedo assembly and awl spring Rubber end, fishing head is provided with through hole, described quick torpedo assembly and awl spring Rubber end via through holes are installed on the fishing head, the size and the external catch fishing tool of fishing head upper end are complementary, and the fishing head lower end links to each other with the stayed mast unit by shear screw.The utility model has solved when instrument and has met card, the technical problem that can not salvage downhole instrument with fishing tool, simultaneously, also solved the existing cable head do not have shear the weakness design, maintenance is loaded down with trivial details and the technical problem of the easy damaged of cable head afterbody.
Chinese patent notification number: CN2256035 provides a kind of " field produces logging cable head ", is to adopt one urceolus, three public tangential pins that the fixedly employing of urceolus and seal head is uniform on diameter 28mm cable head; The sheath that is with external diameter 38mm on the urceolus is threaded on the butt joint cap, the butt joint cover of also external external diameter 38mm on the butt joint cap; This cable head can be connected with the logging instrument of diameter 28 (or 38) mm.Edge armour silk place has annular chamber to be inserted with rotating armour silk cap in the urceolus, is that horn body is shaped on several uniform grooves of embedding armour silk and is with lock sleeve and locking cap forms convenient fixing separate component at armour silk cap one end.
The utility model content
The purpose of this utility model is: a kind of horizontal wellbore logging safety cable head is provided, is used for horizontal wellbore logging, cable can be linked to each other with instrument, and have safety, reliable, energy stable transfer log parameter.Overcome the affected deficiency of prior art log parameter.
The technical solution adopted in the utility model is: horizontal wellbore logging safety cable head, mainly by rope socket, pin, armouring cone, armouring three-piece, connecting cylinder, cut off nail, garter spring, single core sealing column and form.It is characterized in that: rope socket is the cylinder bodily form, and the upper end outer wall of rope socket is a cone shape, and rope socket upper end cone has axial center hole, and axial center hole is the hole that penetrates of cable; The stepped central hole is arranged in the rope socket, it is the cylindrical armouring cone of stairstepping that an outer wall is arranged in the upper top in rope socket stepped central hole, the inwall of armouring cone is a taper seat shape, in the inside of armouring cone the armouring three-piece is arranged, the hollow round platform concentric sets dress of three toroidals that the armouring three-piece is increased progressively successively by internal diameter, material is 35 chrome molybdenums, and cable can pass from the round platform center; Circumferencial direction is evenly distributed with screw on the wall of rope socket, and a screw is arranged in each screw, and the inner of screw screws the upper end that screw can compress the armouring cone on the outer wall of armouring cone upper end, armouring three-piece concentric is fixed.In the centre bore of rope socket lower end connecting cylinder is arranged, connecting cylinder and rope socket lower end concentric are connected.On the rope socket outer wall cannelure is arranged, even distribution shear pin hole in the cannelure of rope socket has one to cut off nail in each shear pin hole, and the inner that cuts off nail riveting is respectively gone in the pin hole of connecting cylinder outer wall; In the outside that cuts off nail a garter spring is arranged, garter spring is an annular, utilizes the spring deformation of garter spring will cut off nail and is fixed in the cannelure of rope socket outer wall; With four pin dowel fixes; In connecting cylinder centre bore lower end cross wall is arranged, the connecting cylinder cross wall has centre bore, is fixed with a single core sealing column in the centre bore of connecting cylinder cross wall.Single core sealing column can link to each other with the lower end tester.
Sketch operating principle of the present utility model and process, help to connect the utility model.Consult Fig. 1.Cable 1 usefulness armouring three-piece 5 is fixed in the rope socket 2, horizontal wellbore logging safety cable head and cable 1 are coupled together, rope socket 2 and connecting cylinder 6 relied on cut off nail 7 and is connected the pulling force size that how much can determine horizontal wellbore logging safety cable head of screw 3.Single core sealing column 9 connects the lower end tester.
