摘要

This paper describes the hardware and operation of a new genera- tion of nuclear magnetic resonance (NMR) logging tools. In the past, NMR required the logging engineer to consider the T_1 relax- ation times of the reservoir fluids likely to be encountered. Actual, or simply assumed, long T_1's translated into slow logging speeds. The new tool generation overcomes this limitation. The key fea- Ture is that nine sensitive volumes are polarized in parallel and are Read out in rapid sequence. A new sonde design speeds up the Polarization process by a factor of 2. Each volume contributes Equally tot he results and can support identical measurements for Rapid stacking and fast logging, and each can be used for individ- Ual, simultaneous measurements.
