Abstract

Abstract: The Carboniferous lay directly over the Ordovician m the Lunnan area, Tarim basin, which acts as the regional sealing bed for Ordovician fractured limestone reservoir, with good capillary and pressure seal properties. Although pressure sealing process occurred later than the period of major hydrocarbon generation, it favors the preservation of accumulated hydrocarbon in this area.

Key words: rarim basin, Lunnan area, Carboniferous, Shale, Caprock, Pressure sealing process
