【 摘 要 】

A history and project summary of the development of a very high-speed drill string communications network are given. The summary includes laboratory and field test results, including recent successes of the system in wells in Oklahoma. A brief explanation of commercialization plans is included. The primary conclusion for this work is that a high data rate communications system can be made sufficiently robust, reliable, and transparent to the end user to be successfully deployed in a down-hole drilling environment. A secondary conclusion is that a networking system with user data bandwidth of at least 1 million bits per second can be built to service any practical depth of well using multiple repeaters (Links), with spacing between the Links of at least 1000 ft.
