Apparatus for well completion operations
This patent describes an apparatus for hydraulically setting a hydraulically set packer within a well bore and for controlling the flow of well fluids ino the apparatus. The apparatus is attached to one end of a tubing string in the well and adapted to selectively sealingly engage the interior of the hydraulically set packer. The apparatus comprises: a seal assembly having one end thereof connected to the tubing string and having seals thereon, a bore therethrough and an annular recess therein; and a hydraulic setting tool assembly connected to the hydraulically set packer for setting the hydraulically set packer in the well, the hydraulic setting tool assembly including: a concentric sleeve having the hydraulically set packer therein; a packer actuating sleeve slidably with respect to the concentric sleeve; a housing releasably secured to the concentric sleeve and having a portion thereof abutting the packer actuating sleeve; an inner mandrel slidable within the housing and engaging a portion of the seal assembly; a piston slidably within the annular space between the housing and the inner mandrel, and a cap secured to a portion of the housing and a portion of the inner mandrel closing the annular space located between the housing and the inner mandrel located above the piston.
