准东地区木垒凹陷二叠系芦草沟组"多元控砂"机制研究
Research on the multi-factor sand-controlling mechanism of Permian Lucaogou Formation in Mulei Sag,Eastern Junggar Basin
摘要
Abstract
To clarify the distribution pattern of sand bodies in the Permian Lucaogou Formation of the Mulei Sag in the eastern Junggar Basin(Zhundong area),based on sedimentology,sequence stratigraphy and other theories,3D seismic data and drilling data are applied to analyze the controlling factors of sand body distribution from the perspectives of paleogeomorphology,sequence and sedimentation.The results show that the sand body distribution of the Permian Lucaogou Formation is jointly controlled by the coupling of paleogeomorphology,sequence and sedimentary microfacies.Paleogeomorphology dominates the distribution zones and development scale of sand bodies;sequence stratigraphy controls the temporal-spatial superposition and distribution characteristics of sand bodies;sedimentary microfacies regulate the development of dominant reservoir sand bodies.The clarification of sand body controlling factors provide a theoretical guidance for the optimization of high-quality exploration targets in the study area.关键词
