Abstract:

According to the igneour rock lithology being related to the components,structure,texture and the origin of formation,as well as variety of rock types and the difficulty in identification,the carboneous igneous rocks in the 69th area,Junggar Basin,are taken as example to set up the data base for identifying igneous rocks by using the rich lithologic infrmation in common well logging data.The logging parameters,such as nature gamma,acoustic wave,resistivity,density and neutron,are optimized to identify igneous rock lithology according to grey connection method after the statistical model of well logging facies and lithofacies is set up.The result indicates that the method can well identify lithology in the area,the correct rate is as high as 90% or above.

Key words: Junggar Basin, 69 Area, igneous rock, lithological identification, grey connection, well logging facies
