Features
American Completion Tool Model RHP-SR is a hydraulic set packer that can be
run in single or multiple zone installations. It is highly recommended for
deviated wells where conditions are not suitable for mechanical or wireline set
packers.No tubing movement is required or generated in order to set the packer. This allows the well to be kept positively controlled at all times because the tubing is landed and the wellhead installed before circulating or displacing well fluids prior to setting the packer. Two or more packers can be set either at once or in any desired sequence. The RHP-SR packer design features bi-directional, one piece slips located below a three element packing system consisting of dual durometer rubber elements. The slips are fully enclosed in a shear pinned slip housing which in turn is protected by a full diameter guide located below the slip housing. The RHP-SR packer requires a means of establishing a maximum of 3,500 psi pressure inside the tubing at the packer (for 7" and smaller). The hydraulic setting chamber is adjustable between 900 to 2,500 PSI which allows the tubing to be pressure tested before the packer begins to stroke and set. Two balanced pistons are utilized during the setting process. The lower piston moves down to set and anchor the slips before the upper piston moves upward to compress the packing. This action imparts the total setting force to both slips and packing thus assuring a positive anchor and pack-off. The pack-off is retained by a one-piece ratchet ring that locks in and stores the setting force applied to both the slips and packing elements. The RHP-SR packer incorporates two methods of release, straight pull or rotation. Both methods are contained in the same releasing nut which is located at the upper end of the packer. Straight pull release is accomplished by shearing a predetermined quantity of brass retaining screws which frees the tubing. Rotation release is accomplished by approximately eight right hand turns of the tubing which also frees the packer. Straight pull then is applied to completely relax the packer for retrieval. The RHP-SR packer can be ordered with only one method of release if desired. A positive acting equalizing valve is also located in the releasing section which automatically opens during the releasing procedure to equalize pressures and allow circulation between the annulus and tubing. In addition, a large diameter fluid by-pass is located inside the packing mandrel which allows fluid passage for rapid retrieving while reducing element swabbing.
