With the continuous improvement of the ShengLi oil region exploration and development, oil and gas exploration objectives become more complex, in order to accelerate the pace of exploration and development, carried out the dissemination and application of NMR logging and NMR logging the number of new technologies, establishment and improvement of the NMR resonance logging technology theory and evaluation methods. Typical example of a large number of on NMR logging in the reservoir property evaluation and parameter calculation, the reservoir is divided and fluid nature of the identification, also introduced its role in production decisions. The above applications of the results are summed up in the practice of exploration and development, to provide meaningful guidance and reference for future exploration and development problems. However, due to nuclear magnetic resonance of factors cannot be applied mechanically; lithology, well conditions and the drilling fluid change should be considered in practical applications.
