Packer downhole, control tool downhole, and method for setting a packer in a well.

摘要

A packer downhole is provided for positioning in a well to establish a seal with a surrounding surface.The packer includes a sealing element which is sensitive to compression by a piston fixed to expand radially inside the shaft.An actuator is provided to move longitudinally in the piston for setting in response to a signal telemetry received by the packer downhole.The acuador may include a hydraulic pump, a motor operable to control the valve electromechanical or hydraulic energy to apply a force to the piston downhole setting.
