Description
Technical field
The utility model relates to a kind of horizontal wellbore logging cable wellhead guider in well logging servicing unit technical field, the guiding for horizontal wellbore logging cable at well head.
Background technology
Carrying out in horizontal wellbore logging, cable is in the annular space of drilling rod and sleeve pipe more than bypass short joint, and must be all the time in tension, so just can guarantee to fathom accurately, drilling tool need to dock, dismantles and remove simultaneously.Remove and keep cable all the time in tension in order not affect drilling tool, avoiding breaking cable and cause the accident, need to utilize pulley that cable is guided to a side, to meet well logging needs.
In current domestic horizontal wellbore logging construction, wellhead cable guiding adopts traditional leading block to be directly welded on the mode of well head by bracing frame, its shortcoming is: 1, leading block is adjusted after direction at well head, owing to fixing, need to use electric welding, by welded together to pulley support frame and drilling well-head.2, Site Welding needs electricity consumption, and welding personnel need possess qualification, holds operation card, and thunderstorm weather can not be constructed.3, after well logging, need to use sledgehammer to break or cut solder joint, regain pulley, shorten the useful life of pulley.4, complex procedures, the seat pulley set-up time is long, and labour intensity is larger.5, without the maintenance such as bearing, grease nipple design, when pulley damages or has problem, can only entirety eliminate, use cost is high.
Summary of the invention
The purpose of this utility model is to solve the technical problem that traditional well head pulley exists, and provides a kind of and eliminates safe hidden trouble, improves the horizontal wellbore logging cable wellhead guider of logging well timeliness, increasing the service life, reducing costs.
The technical solution of the utility model is:
Horizontal wellbore logging cable wellhead guider, comprise pulley and bracing frame, pulley is fixed on and is sat on pulley body by bracing frame, the bottom surface of sitting pulley body adopts slab construction, along the seat pulley body intrinsic piece that articulates downwards of pulley notch direction, articulate piece outer face and be provided with arc groove, arc groove and pulley notch remain on same working face.
Such scheme also comprises:
Pulley is connected with bracing frame with bearing pin cap by bearing, bearing pin, and pulley notch is for adding deep structure.
On the bearing pin cap of pulley, be provided with grease nipple, on seat pulley body, be provided with carrying handle.
The described piece that articulates comprises angle steel, partly cuts open steel pipe or steel plate, and perpendicular to sitting pulley body.
Be provided with interior double wedge in the bottom that articulates piece.
The utility model has adopted seat pulley body to be provided with and has articulated piece, bracing frame and carrying handle, and the safety that articulates piece realization seat pulley body and drilling well-head articulates; Pulley with articulate the groove fit of piece, realize in horizontal wellbore logging construction logging cable in the guiding of well head; Pulley has fixedly been reduced and has been worn and torn and be convenient to repair and replacement by bearing, bearing pin and bearing pin cap and bracing frame; Grease nipple is realized the lubricating maintenance to bearing.
Compared with prior art, horizontal wellbore logging cable wellhead guider has following characteristics:
1, adopt the mode articulating to be directly sitting in well head, do not need electricity consumption, do not need welding, do not need hammer to pound.
The potential safety hazard such as 2, eliminated electricity consumption, electric welding, injure by a crashing object.
3, the set-up time short, improve well logging timeliness.
4, be easy to maintenance, design increases bearing, grease nipple, has increased useful life, saves logging cost;
5, pulley groove is deepened, and cable, not in groove, avoids cable to be damaged or touch by elevator breaking well etc. to cause irremediable accident.
Brief description of the drawings
The schematic diagram of a kind of embodiment of accompanying drawing 1 the utility model
Accompanying drawing 2 is the on-the-spot schematic diagrames that use of a kind of embodiment.
Embodiment
By reference to the accompanying drawings, the utility model will be further described:
As shown in Figure 1, the related parts of horizontal wellbore logging cable wellhead guider comprise seat pulley body 1, pulley 2, pulley fixing device 3, grease nipple 4, carrying handle 5, bracing frame 6, articulate piece 7.
Wherein, pulley adopts abrasionproof pulley 2 to be fixed on and to be sat on pulley body 1 by bracing frame 6, the bottom surface of sitting pulley body 1 adopts slab construction, along the downward intrinsic piece 7 that articulates of seat pulley body 1 of pulley 2 notch directions, articulate piece 7 outer faces and be provided with arc groove (dash area in figure), arc groove and pulley notch remain on same working face.Articulate piece 7 and realize and sit pulley bodies 1 and articulate with the safe and convenient of drilling well-head, hanging device 7 adopts groove design, and logging cable removes and in process, there will not be abrasion condition;
Pulley 2 is connected with bracing frame 6 by bearing, bearing pin and the pulley fixing device 3 of bearing pin cap composition, and pulley notch is for adding deep structure.In the time that 2 wearing and tearing of abrasionproof pulley need to be changed, dismounting pulley fixing device 3, takes off abrasionproof pulley 2 and changes; Abrasionproof pulley 2 grooves are deepened, and logging cable, not in groove, has effectively avoided logging cable in horizontal wellbore logging construction to be damaged or touch disconnected hidden danger by elevator or drilling rod.
On the bearing pin cap of pulley, be provided with grease nipple 4, grease nipple 4 is realized the regularly lubricating maintenance to bearing; On seat pulley body 1, be provided with carrying handle 5, be convenient to carrying and on-the-spot installation.
The described piece 7 that articulates comprises angle steel, partly cuts open steel pipe or steel plate, and perpendicular to sitting pulley body.Be provided with interior double wedge in the bottom that articulates piece.Articulate piece 7 and adopt angle steel, partly cut open after the structure of steel pipe, be conveniently connected with the corner of well head rotating disk; Steel plate is used on arbitrary limit.The interior double wedge of setting up acts on the lower limb of well head rotating disk, further prevents the activity of whole device.
On-the-spot operation instruction: as shown in Figure 2, the on-the-spot use of horizontal wellbore logging relates to horizontal wellbore logging cable wellhead guider 8, drilling well-head rotating disk 9, logging cable 10, drilling rod 11.
When horizontal wellbore logging construction, horizontal wellbore logging cable wellhead guider 8 is connected to drilling well-head rotating disk 9 one sides by articulating piece; Logging cable 10 enters drilling well-head by abrasionproof pulley guiding; Drilling rod 11 transfer and on carry in process logging cable 10 all the time in tension, the active force that logging cable 10 applies horizontal wellbore logging cable wellhead guider 8 with articulate piece and coordinate, make horizontal wellbore logging cable wellhead guiding sit pulley 8 more firm with being connected of drilling well-head rotating disk 9, realize the guiding of logging cable 10 at well head.
