Western Gas Sands Project, Los Alamos NMR Well Logging Tool Development. Progress Report, October 1, 1981-September 30, 1982

摘要

During the period October 1, 1981, through September 30, 1982, considerable progress was made in the development of a nuclear magnetic resonance (NMR) logging tool and in the laboratory studies required to interpret and understand the data received when operating the tool. A pre-prototype tool using permanent magnets has been operated in the laboratory, and preparations are in progress for the first downhole test of this tool. New, improved electronics have been designed, built, and tested. Components for a laboratory version of a tool that uses superconducting magnets have been received and are ready for assembly and testing. Improved data acquisition equipment has been acquired and tested. A very exciting development in the program on laboratory NMR studies of synthetic samples and Western Gas Sands core resulted in the first successful extraction of a pore-size distribution from NMR relaxation data. 27 figures, 2 tables.
