Karst Development Mode of Ordovician Carbonate Rocks in Lunnan Swell in Tabei Area, Tarim Basin

Abstract

Abstract: The large area of platform-facies deposits of the Cambro-Ordovician in Tarim basin provides foundation for the post-karst reservoir development in Lunnan area, which can be classified as the buried-hill exposure karst, bedding confined water karst, penecontemporaneous interlayer karst and commingled water karst, etc., with multi-cycle and multi-stage exposure features. The study shows that tectonic movement is of crucial effect on the karsts development and related reservoir formation in this area.

Key words: Tarim basin, platform facies, multi-stage exposure, buried hill, confined karst
