Function and Operating Principle of Double Grip High Pressure Retrievable Packer

 

The Construction of the Full Bore Mechanical Setting Packer is named as RTTS packer. The mechanical set double grip 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.
1. Application 

RTTS is a mechanical slip packer, mainly applied to formation testing in high temperature and pressure, oil extraction, water injection, water exploration, plugging, squeezing acidification, fracturing and so on.

2. Structure and Principle 

RTTS packer consists of hydraulic anchor, rubber barrel, slip holder, slip, slip bracket, reversingfriction block, outer central pipe, inner central pipe, upper joint and so on.

RTTS mechanical slip packer is supported by unidirectional slip. It's set by pulling, turning and 

lowering. Released by pulling the column.

3. Characteristics 

1) The rubber barrel is above the slip in order to avoid covering by sand.

2) Simple structure and easy to operate.
