Downhole Testing High Pressure Retrievable Packer RTTS packer

 

How to operate the RTTS packer

 

The RTTS Packer is hookwall type packer with full opening design, which can segregate bidirectional pressure designed for use in testing, treating, and squeeze cementing operations. The full bore of the RTTS packer permits pumping large volumes of fluid with a minimum pressure drop, and allows the passage of a through tubing type perforating gun

 

The Construction of the RTTS packer is shown in the accompanying figure. When starting the RTTS packer into the hole, place J-slot in the drag block sleeve in the locked position. The RTTS packer will be run slightly below the desired setting position and is then picked up tool to setting position and rotated pipe several turns to right.

Holding right torque in pipe, slack off the pipe weight until mechanical slips on the tool set and start taking weight .At the same time the packer element is compressed against the wall of the casing, then the packer can isolate the annular from the test zone.

Self-guard hydraulic hold down mechanism can prevent the packer from bouncing up because of the high pressure below the packer.
