【 摘 要 】

Halliburton Energy Services and Oak Ridge National Laboratory established a CRADA to conduct applied research to develop a general purpose, High-Temperature, Smart Transducer Interface Node and Telemetry System (HSTINTS) capable of temporally-coherent multiple-channel, high speed, high-resolution data transuction and acquisition while operating in a hostile thermal, chemical, and pressure environment for extended periods of time over a single coaxial cable. This ambitious, high-risk effort required development of custom dielectric isolated integrated circuits, amplified hybrid couplers for telemetry and an audio-frequency based power supply and distribution system using an engineered application of standing waves to compensate voltage drop along a 2 mile long cable. Several goals were achieved but underestimated challenges and a couple of mistakes hampered progress. When it was determined that an additional year of concerted effort would be required to complete the system demonstration, the sponsor withdrew funding and terminated the effort.
