Subsurface injection tool
A tool is described for use in a well bore for producing hydrocarbons through a tubing string from subterranean hydrocarbon-bearing formations having a vertically spaced perforations therein. The tool consists of a tubular body assembly; radially expandable and retractable packing elements mounted in axially spaced relation on the tubular body assembly, each of the elements comprising means for sealing the annular area between the tubing string and the well bore upon radial expansion thereof; a rigid mandrel assembly attachable to the tubing string, insertable in the tubular body assembly, and having a mandrel bore communicable with the tubing string; at least one horizontal locking groove extending partially around the exterior of the mandrel; means on the interior of the tubular body assembly defining a toothed segment engagable with the locking groove during run-in to secure the mandrel against movement relative to the tubular body assembly; the mandrel being releasable from the tubular body assembly by limited angular movement relative to the tubular body assembly; means for expanding and retracting the packing elements upon axial manipulation of the mandrel relative to the tubular body assembly; a radial injection path communicable between the mandrel bore and the exterior of the tool, at least one upper packing element being above the injection path, and at least one lower packing element being below the radial injection path; means for sealing the mandrel bore below the injection path.
