Description

Full BoreFull Bore Retrievable Packer Mechanical Setting RTTS Packer

The Full Bore Test Packer is a kind of retrievable packer with mechanical setting, the packer is specially designed for Full Bore Drill Stem Testing (DST) and Tubing Conveyed Perforating (TCP) operations.

During TCP operations where the detonation of the TCP charges can cause rapid pressure surges, the hydraulic hold downs react to prevent packer movement. The full opening design of the packer allows unrestricted fluid flow and tool movement through the tubing bore. A pressure balanced bypass valve which is held open when running and retrieving, prevents swabbing effect. The valve also allows debris to be washed from the top of the packer when releasing. The bypass valve (circulating valve ) is held closed by pressure from below and in turn helps prevent upward movement of tubing.
