Drill stem testing tools circulating valve RTTS circulating valve
High Pressure Drill stem testing tools circulating valve RTTS
The RTTS circulating valve can be run directly above the packer body or the top of RTTS safty joint further up the work string. When placed in the hole, the valve must be in the locked-open position. The J-slot in the packer-body drag block (or drag sleeve) must also be placed in the unset position. Pls note that the drag block sleeve slide upward when down string. That will lead to packer stuck and circulating valve close. Close the valve through the string rotation on ground.
