  • Method and apparatus for mud pulse telemetry
    Patent number: 7468679
    Abstract: An apparatus for mud pulse telemetry for transmitting information from a drill string positioned at a down hole location in a bore hole to a surface location, the drill string having a flow passage through which a drilling fluid flows is provided. In one aspect, the apparatus includes a rotor pulser having an uncompensated drive train comprising a unique uncompensated seal comprising a stacked array of seal elements. The uncompensated drive train provides for the direct coupling of a rotor to a drive motor. The drive motor is located within an internal housing that is filled with gas at atmospheric pressure. Additionally, a method of operating the apparatus is provided. The method includes measuring drilling fluid pressure within the flow passage to determine when a pipe connection is being made to the drill string to initiate the measurement of a down hole parameter. The down hole parameter information is transmitted to the surface through a series of encode pressure pulse generated in the drilling fluid.
