Function and Operating Principle of the RTTS packer

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 tool is run slightly

below the desired setting position and is then picked up tool to setting position and rotated pipe several

turns to right(on bottom, only 1/2 turn is required).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. When it is extra, pressure can be into the annular space between the

volume tube, hydraulic hold down body and the lower mandrel through the radial hole on the lower

mandrel, then to reach the round hydraulic hold down slip and compress the slip retractor spring, then

the round hydraulic hold down slip lean against the inside wall of the casing closely and help prevent

the tool from being pumped up the hole.
