In recent years, volcanic rock reservoir exploration has become a hot spot in Turpan-Hami Oilfield, and breakthrough has been made in different strata of volcanic rock reservoir. The reservoirs have been affected more greatly by its complex and variable lithology than the fluid, so lithology recognition is particularly important in the area.Accurate description of the lithology of volcanic rocks is the basis for precise reservoir evaluation of such type and is the major problemfor logging evaluation. In this paper, a newtechnique is developed based on volcanic rock slices data of Kalagang Formation ofMalang Depression in Santanghu Basin. It uses conventional logging information to identify the mineral composition, and applies imaging logging information to identify the volcanic rocks and tectonic structure, and finally integrates them into volcanic rock lithology comprehensive identification, which is suited for the Turpan-Hami Oilfield. The method has got good application effect in the lighology identification in Malang Depression.
