    摘要: A wire line mass or bird nest is retrieved from a well bore by running into the well bore a coiled rod such that a lower pointed end of the coiled rod engages the wire line mass. The coiled rod is rotated to draw the wire line mass upwardly into entangled relationship with the coiled rod; whereupon the coiled rod and wire line mass can be removed together from the well bore. Outward projections on the coil rod prevent the wire line mass from slipping off the coiled rod.
