Characteristics of the Permian sequence stratigraphy and the paleogeographic environment in South Guizhou sag, China
摘要
Abstract
The Permian strata in the South Guizhou sag are well developed and the characteristics of sedimentary differentiation are significant. Therefore, the Permian strata in the South Guizhou sag are of important petroleum geological significance. This paper uses the relevant theories and research methods with the outcrop sequence stratigraphy. Based on the detailed sedimentologic investigations and refined strata division and correlation, The Permian strata from Longlinian stage to Changxing stage are divided into two incomplete super sequences and 12 third-order sequences, and the sequences are correlated. Taking the super-sequence system tract as the mapping unit, the sequence-lithofacies paleogeography map of each stage in Permian is compiled systematically and the evolutionary features of the paleogeography are discussed combined with the factors such as the sea level change, tectonic activities and characteristics of carbonate growth. The authors think that the compensation sediments in the platform-basin are good source rocks and the high energy shoal inside the carbonate platform and the high energy reef-bank association on the platform margin are favorable reservoir facies belts.关键词
