摘要
Jiantianba of Lichuan, western Hubei Province, is located in platform margin facies between carbonate platform facies in the eastern Sichuan and Western Hubei Trough. Based on the multi-disciplinary analysis of measured profiles, the authors discussed the reef composition and forming model of Changxing Formation reef in Jiantianba section. The study demonstrated that the study area developed two third-order sequences in Changxing depositional stage of Late Permian and the body of reef in the Jiantianba of Lichuan was located in HST of sequence 1 of Changxing Formation. Reefs in Jiantianba of Lichuan reservoir system mainly distributed at the top of the HST, the environment for the formation include platform edge bioherm, platform edge reef and restricted platform dolomite deposition at the top of reef, high quality reservoir is closely related to the reef composition and deposition conditions.
