Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
The calker that the present embodiment provides a kind of mechanical type to set and reclaim, as shown in Figure 1, recovery set 1, Inserting Tube 2, conversion head 3, sheath 4, spring 5, slip spider 6, upper slips 7, lower slips 23, baffle ring, snap ring, J type body 11, upper cone 12, hypocentrum, lining 13, packing element, joint ring 18, spacer ring 19, extension set 21, brake pad 24, central tube 22, traction body 30, lower contact 31 and shear pin 10 is comprised.
Recovery set 1 to be connected with Inserting Tube 2 by inner hook groove or to depart from, and can transmitting torque; Conversion head 3 top is threaded with Inserting Tube 2, and bottom is threaded with central tube 22.
Sheath 4 inside is provided with spring 5, and upper slips 7 is connected in slip spider 6 by special-shaped groove, and sheath 4, spring 5, upper slips 7, slip spider 6 concentric locking collar are on central tube 22.Slip spider 6 is against on spring 5 indirectly, can provide pretightning force when setting.Upper slips 7, to compressible spring during top offset 5, improves slips and sets performance.
As shown in Figure 2, J type body 11 is placed in central tube 22, and is fixed by shear pin 10 and central tube 22, adds extra deblocking mode, has urgent release function.J type body 11 top is located by snap ring.
Lining 13 top is threaded connection upper cone 12, and bottom cover has lower cone 20, and middle part is provided with cartridge, and cartridge is divided into first end packing element 15, middle packing element 16, second end packing element 17 3 sections.Lining 13 body is provided with screw 14, and is connected with J type body 11 by this screw 14, setting force can be locked and prevent unexpected deblocking.Fitting tight ring 18 inside lining 13.
Traction body 30 outside is provided with brake pad 24 and is fixed by brake pad spring 25, and traction body 30 top is provided with lower slips 23, and both are coordinated by inner groove milling.
Lower contact 31 is connected with central tube 22 by screw thread.
Further, as shown in Figure 3, described J type body 11 is tubular structure, is evenly arranged some Openworks shape hook grooves along its circumference, and for a series of through holes that shear pin passes.J type body is innovative design important in this instrument, and it only just achieves cleverly with hook groove and shear pin and sets, and conventional deblocking and urgent decapsulation functions, greatly reduce tool length, enter performance under adding instrument.Conventional products these several functions need several structure to realize usually on the market, and this can cause instrument long usually, being decreased through property, increase construction risk.
Further, described lining 13 inside is provided with joint ring 18, can coordinate close bypass with central tube 22.
Further, described upper cone 12 has claw-like saw kerf, is convenient to release and reclaims, can improve the reliability of deblocking.
Further, described traction body 30 is designed with hook groove, is connected with lower contact 31 by the bolt 29 be arranged in lower contact 31, can guarantee that traction body 30 is reliably connected with central tube 22 or departs from.
Operating principle of the present invention is: when needs temporary plugging layer position, under enter this calker, moment of torsion is provided by rotating tubing string, the bolt 29 installed in lower contact 31 is departed from traction body 30 hook groove, thus release central tube 22, continue to transfer central tube 22 and can allow the upper slips 7 be connected on central tube 22, cartridge (first end packing element 15, middle packing element 16, second end packing element 17) etc. start descending and contact grappling with lower slips 23, now, the sealing surface of joint ring 18 can contact with central tube 22 and close bypass.The strength that central tube 22 is transferred in lasting increasing can make packing element compression set, slips anchoring, and the screw 14 now in lining 13 can enter the hook groove interior locking setting force of J type body 11 thus complete the process of setting.In like manner, also need when needs reclaim this calker to rotate tubing string, the screw 14 in lining 13 is departed from the hook groove of J type body 11, then can directly on carry central tube 22, now outside slips, cone, packing element etc. can automatically shrink resilience thus complete instrument removal process.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvement or distortion, these improve or distortion also should be considered as protection scope of the present invention.
