摘要： Methods and apparatus for communicating between surface equipment and downhole equipment. One embodiment of the invention provides a wellhead assembly that allows electrical power and signals to pass into and out of the well during drilling operations, without removing the valve structure above the wellhead. Another embodiment of the invention provides an electromagnetic casing antenna system for two-way communication with downhole tools. Another embodiment of the invention provides an antenna module for a resistivity sub that effectively controls and seals the primary/secondary interface gap.

摘要： A hydraulic sleeve valve is disclosed that comprises a bypass relief system that provides an indication that the valve has reached a predetermined position, such as, for example, the fully opened or fully closed condition. The bypass relief may also provide a valve control fluid circulation function to filter or otherwise manipulate the control fluid. Also disclosed are flow port alignment systems that maintain the valve flow ports in predetermined relationships.
