METHOD TO TRANSMIT DOWNHOLE VIDEO UP STANDARD WIRELINE CABLE USING DIGITAL DATA COMPRESSION TECHNIQUES |
摘要 |
Disclosed is a downhole video system that is suitable for use with a standard wireline transmission line, without the need for coaxial or fiber optic cable. A downhole video camera transmits a digitized video signal that may be multiplexed with orientation, sound, and other telemetry data. At the surface, an enhanced video is displayed simultaneously with processed sound to give an operator a better understanding of the conditions downhole. In addition, multiple modes are provided, including a "burst" mode to provide high resolution, full motion video, thereby circumventing the severe bandwidth limitations of standard electrical transmission lines. |
