Study of igneous rocks igneous rock lithology on the basis of oil and gas reservoirs, the Junggar Basin in western drop various types of igneous rock lithology, complex lithology. As a result of fragmentation, alteration, such as the effects of zeolite, the same lithology log the information it is difficult to determine the distribution function, resulting in the use of fuzzy mathematics to identify lithology it is difficult to determine when its membership function. Expanded sample of the sample is a reasonable expansion, construction of a new series of lithologic samples, and in line with the normal distribution for each sample, and then use the normal distribution function, correspondence analysis, hierarchical analysis of its membership function, using the maximum the principle of membership lithology identification, identified a total of 14 kinds of igneous rock lithology, two kinds of sedimentary rocks to identify more than 80%, error of lithology mainly tuff and volcanic brec
