The BR-TTSRP packer is a full-opening, hook wall packer used for testing, treating, and squeeze cementing operations. In most cases, the tool runs with a circulating valve assembly.
The packer body includes a J-slot mechanism, mechanical slips, packing elements, and hydraulic slips. Large, heavy-duty slips in the hydraulic hold-down mechanism help prevent the tool from being pumped up the hole. Automatic J-slot sleeves are standard equipment on all packer bodies.
The circulating valve, if used, is a locked-open/locked- closed type that serves as both a circulating valve and bypass. The valve automatically locks in the closed position when the packer sets. During testing or squeezing operations, the lock prevents the valve from being pumped open. A straight J-slot in the locked-open position matches with a straight J-slot (optional) in the packer body. This combination eliminates the need to turn the tubing to close the circulating valve or reset the packer after the tubing has been displaced with cement.
The packing elements can be compressed and expanded against the wall of the casing, isolate the annular from the test zone. Hydraulic hold down mechanism round slips can lean against the inside wall of casing closely and help prevent the tool from being pumped up the hole.
