But the described exhaust cable-passing packer of the utility model comprises box cupling, top connection, cable, capillary tube, upper plug head, mandrel, packing element, upper piston, lower piston, urceolus, lock tube, lock ring, load cover, shear pin, inner central tube, exterior central tube, upper cone, slips, slip sleeve, shop bolt, lower cone, deblocking pin, separates big envelope, steam vent, lower end cap.Said box cupling is connected with top connection, mandrel, inner central tube in order; Be connected with exterior central tube under the mandrel in order, separate big envelope, lower end cap, mandrel is equipped with upper plug head, packing element, upper piston, lower piston, urceolus, lock tube, load cover, upper cone, slips, slip sleeve, lower cone outward in order.
Wherein, in the urceolus of said load set upper side, the space between the lock tube lock ring is installed.Said load cover is fixed by shear pin and lock tube.Said slip sleeve is fixed together by shop bolt and lower cone.Said lower cone is pinned and is separated big envelope by deblocking and is fixed together.Under the said mandrel, outer, the exterior central tube of inner central tube, separate and be provided with annular space in the big envelope.On the said mandrel capillary tube is installed, is connected with annular space.Said mandrel is provided with the vertical line duct, cable outside the duct of upper plug head, axis duct and inner central tube on the mandrel, exterior central tube, separate the annular space that is provided with in the big envelope, the duct on the lower end cap is passed.The external surface of said lock tube is designed with the gingival cyst of mucous gland in the newborn button, is meshed with the gingival cyst of mucous gland in the newborn button of lock ring.Said bottom of separating big envelope is provided with steam vent.
The utility model has following advantage compared with prior art:
1, adopted the bi-directional slip grappling, grappling is reliable;
2, the opening and closing of Ground Control outlet valve can be adopted, exclusion sleeve gas or well-flushing can be realized;
3, can realize the pressure test function of oil reservoir with the supporting application of capillary tube.
4, can realize the function of conventional cable-passing packer, and satisfy the needs of sucker rod pump exploitation.
5, concentric, the convenient fishing, safe and reliable of structure.
