Sequence Stratigraphy Analysis and Reservoir Evaluation of Reef of Changxing Formation in Huajiaoping of Lichuan
Abstract: Huajiaoping of Lichuan is located in platform margin facies between carbonate platform facies in eastern Sichuan and Western Hubei Trough. In the study area, the water gradually changed from the deep to shallow in the stage of Changxing Formation of Late Permian, and developed a huge scale of platform margin reef deposition in aggradation- progradation. Through the multidisciplinary analysis of measured profiles, the authors made an in-depth analysis on the Huajiaoping reef sequence stratigraphy and reservoir. The study demonstrated that the body of reef in the Huajiaoping of Lichuan was located in HST of sequence 1 and TST of sequence 2 of Changxing Formation, and internally consti- tuted by the four parasequence sets. As the relative sea level fell gradually and hydrodynamic force improved progres- sively, the reef in the Huajiaoping had experienced four stages of evolution, including the foundation stage, the initial flourishing stage, the prosperous stage, and the organic reef declining stage.
