Packer with hydraulic setting for communication with the Piston ring

摘要

A Packer is set hydraulically a mandrel with an internal Orifice and a Port that communicates with the outside of the Inner Hole of the mandrel.A packaging Element arranged in the mandrel can be compressed by a piston to engage the Shaft.The Piston is arranged in the mandrel of a First side of the Packing Element and moves against the Packing Element when the Pressure Pipe is communicated to a First Chamber piston to tTake the Port of mandrel.To increase the strength of fixation.A Sleeve is arranged between the mandrel and the Packing Element defines a space that communicates an opposite side of the Packing element with a Second pressure Chamber piston.During the operation of high pressure, the high pressure of the first side of the Packing Element acts on the High Pressure side of the first pistonIncreasing the piston movement from a high pressure region to a low pressure region.
