Description
Technical field
This utility model relates to a kind of sucker rod socket, belongs to oil well repairing operation bar class falling object fishing tool technology neck
Territory.
Background technology
In oil well production process, sucker rod is the disconnected well phenomenon that comes off because the reasons such as burn into eccentric wear can produce, because of casing annulus
Greatly, sucker rod can produce flexural deformation, top of fish is close to the complex situations of casing wall, brings certain difficulty to workover treatment, often
The bent rod Refloatation method of rule is that the operations such as first printing, milling change top of fish, re-uses loose-leaf fishing socket, three ball fishers
Instrument is salvaged, and flow chart is loaded down with trivial details, and success rate is low, increases labor intensity, adds operating cost.
Patent No. CN204609820U discloses and drags for fishing socket outside the sucker rod of a kind of band guide shoe, including Shang Liangai, main cylinder,
Guide block on guide shoe, claw, hoodle, the first compression spring, guide pin bushing, the first index pin, the second index pin, claw, claw lower guide block,
Guide shoe guide groove, hoodle chute, the second compression spring, guide pin bushing guide groove, hoodle installing hole, guide shoe pin-and-hole, upper even cancelling hole, card tooth.
Drag for fishing socket simple in construction outside this sucker rod, improve the efficiency that sucker rod is salvaged.But for easily make sucker rod gross distortion,
Top of fish is close to the complex hole condition of casing wall, it is difficult to realize disposably salvaging purpose.
Utility model content
The purpose of this utility model is that above-mentioned salvaging operation of the prior art is loaded down with trivial details, salvage lacking of weak effect in order to overcome
Fall into, it is provided that a kind of high efficiency bent rod fishing socket, shorten the well workover time, reduce labor intensity.
Sucker rod socket of the present utility model, is made up of top connection, cylinder, spring, slips, top connection by screw thread with
Cylinder connects, and is provided with the undergauge section that upper and lower two ends are taper in the middle part of cylinder lumen, and the lower conical surface of its undergauge section is provided with thread making screw thread,
The upper conical surface has spacing sliding tray, is provided with spring and slips in spacing sliding tray.
At least 2 spacing sliding trays, spacing sliding tray is had on the upper conical surface of the undergauge section in the middle part of described cylinder lumen
Spring and slips are inside installed.
Described cylinder bottom has axial guiding slot, is provided with chamfering at the edge of opening of guide channel.
The beneficial effects of the utility model are to have lead-ingroove in salvaging side, cylinder bottom, add in fishing socket body
Footpath, easily will be close to casing wall bent rod import cylinder, and with slips, salvage screw thread efficient combination, by slips
Junk is pulled out by radial clamping force or salvaging screw thread thread making function, easy to operate, improves salvaging efficiency, has saved operation one-tenth
This.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
As it is shown in figure 1, sucker rod socket of the present utility model, it is made up of top connection 1, cylinder 2, spring 3, slips 4, on
Joint 1 is connected with cylinder 2 by screw thread, is provided with the undergauge section that upper and lower two ends are taper, under its undergauge section in the middle part of cylinder 2 inner chamber
The conical surface is provided with thread making screw thread 6, and the upper conical surface has spacing sliding tray 5, is provided with spring 3 and slips 4 in spacing sliding tray 5.
At least 2 spacing sliding trays 5, spacing slip is had on the upper conical surface of the described undergauge section in the middle part of cylinder 2 inner chamber
Spring 3 and slips 4 are installed in groove 5.
Described cylinder 2 bottom has axial guiding slot 7, is provided with chamfering at the edge of opening of guide channel 7.
When salvaging well bent rod, by the top connection 1 of sucker rod socket of the present utility model by screw thread with
Running string connects, and at top of fish, positive rotation tubing string, under the effect of brill dish moment of torsion and the pressure of the drill, guide channel 7 will be close to sleeve pipe
The bent rod of wall introduces cylinder 2 inner chamber, and containing up along the conical surface under cylinder 2 inner chamber, if falling well bent rod top
Being the vertical shape body of rod of certain length, head pushes up slips 4, slips 4 compression spring 3 along the passage of the undergauge section of taper, makes bar
The latch that body is close to slips 4 is up, upper lifting pipe post, and frictional force and the expansionary force of spring 3 between the latch and the body of rod of slips 4 are total to
Under same-action, descending with slips 4, make slips 4 produce radial clamping force and bite the body of rod, continue upper lifting pipe post by lost sucker rod
Take out of；If head folds in well and downwards, under the effect of rotary presser, enters the bending oil pumping of 2 times conical surface inner chambers of cylinder
Bar is tightened compacting, is pulled out by thread making screw thread 6 thread making of 2 times conical surfaces of cylinder, and operational approach is simple, the most effectively, it is ensured that
Salvage efficiency.
