摘要
粘土矿物研究在塔里木盆地油气勘探中见到了明显效果。可用于推断古气候、沉积相带及成岩环境的变化,为地层对比及沉积间断研究提供依据。储集层物性不仅与粘土矿物种类有关,还与它的形态及产状有关。粘土矿物研究成果对测井解释有重要作用。克拉2大气田古近系-白垩系储气层存在大量自生高岭石,可作为追踪气源岩的重要标志之一。
Clay mineral research plays an important role in the oil and gas exploration in Tarim basin. Clay minerals can be applied to inferences of paleoelimate, sedimentary facies and diagenetie environment evolution, providing bases for stratigraphie correlation and depositional break. Reservoir petrophysies is not only related to clay mineral types, but also to their morphologie characteristics and occurrences. The results from clay mineral research can also help the well log interpretation. The abundant authigenic kaolinites distributed in Eocene-Cretaceous （E-K） reservoirs can be as one of the significant indications for tracing the gas source rocks in Kela-2 gas field.
