| Abstract: | Shahezi formation is the product of a quiet period of intermittent volcano,between two main volcanic products of Huoshiling and Yingcheng formation. It's also the main gas source of the Yingcheng formation volcanic gas reservoir in Xujiaweizi depression. On the basis of the study on whole Xujiaweizi depression, the authors analyze the distribution and growth characteristics of the Shahezi formation, using the three-dimensional seismic and drilling data. Based on the analysis of existing types of sedimentary facies, the spatial distribution of Shahezi formation sedimentary facies is predicted, indicating the features of the formation centered at the lake with surrounding water systems converging to the depression. The whole sedimentary facies of Shahezi formation evolved from the lower segment of the lake environment to the upper segment fluvial environment, which reflects the trend of the water expansion to contraction. Based on their mode of occurrence, stratigraphic contact relationship and typical deposition, the isolated volcanic edifice developed on the Xuxi fault should be attributed to the period of Shahezi. |
