Abstract: Evaluation of reservoir lithology recognition technology, is the foundation of reservoir and the reservoir comprehensive evaluation, and its precision directly affects the effect of reservoir evaluation, determine the level of fluid identification, capacity evaluation and precision. Portugal's west oil field, the black temple putaohua reservoir sedimentary environment is complex, because of its sedimentary environments and different hydrodynamic conditions, cause different sand body on the rock constituents, lithology involving powder sandstone and argillaceous siltstone, silty mudstone, mudstone, etc. Based on Portugal's west oil, the black temple putaohua oil layer in the particularity of geographic, sedimentary environment, cannot copy and paraphrasing from other parts of the existing interpretation result. In the understanding of the black temple, putaohua reservoir characteristics on the basis of sedimentary environment and establish corresponding relations between logging data and rock lithology lithologic identification methods should be a more suitable research train of thought.
