Abstract: Clay mineral research plays an important role in the oil and gas exploration in Tarim basin. Clay minerals can be applied to inferences of paleoclimate, sedimentary facies and diagenetic environment evolution, providing bases for stratigraphic correlation and depositional break. Reservoir petrophysics is not only related to clay mineral types, but also to their morphologic characteristic8 and occurrences. The results from clay mineral research can also help the well log interpretation. The abundant authigenic kaolinites dstributod in Eocene-Cretaceous (E-K) reservoirs can be as one of the sigmificant indications for tracing the gas source rocks in Kela-2 gas field.

Key words: clay mineral, Tarim basin, paleoenvironment, straigraphic correlation, reservoir petrophysics, well log interpretation, gas source rock
