Oilfield Mechanical Set Double Grip High Pressure Retrievable Packer RTTS Packer
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.

Operation Method of the RTTS Packer
* Before the retrievable packer is run into the well, it should be hung up, shift the drag block sleeve high and lower for may times, check whether the mechanical slip moves flexibly.
* When starting the RTTS packer into the hole, locking open the circulating valve. Place J-slot in the drag lock(or drag spring) sleeve in the locked position. The slip should be in the shrinkage state.
* During running into the hole, slippage will tend to set slips and close the circulating valve. To reopen circulating valve when it has inadvertently been closed. you must pick up the tubing and turn to right, then picks the tubing up to the position, which the circulating valve is open. Turn tubing to left to the locking open position. Take care not back off tubing.
* When the tool is run to the test position and ready for operation, run it slightly below the desired setting position at first, then pick it up to the setting position.
