High-resolution Sequence Stratigraphic Characterization and Sand Body Prediction of the Lower Triassic Formatin in Xiquan(XIQ) Area of Eastern Junggar Basin
摘要
Abstract
Based on core logging and 3D-seismic data, the high-resolution sequence stratigraphy of the Jiucaiyuanzi formation of the Lower Triassic Formatin in XIQ area of Eastern Junggar Basin is studied. Three kinds of short-term base-level cycles, five intermediate-term base-level cycles, and two long-term base-level cycles can be identified with the technology of division and correlation of the high-resolution sequence stratigraphic theory. Based on the base-level cycles, reservoir sands in different sequences are predicted with the technology of the frequency-divided inversion. Base-level changes control the spatial distribution of the sandstone of the Jiucaiyuanzi formation of the lower Triassic Formatin in XIQ area. The favorable sand bodies are predicted. The targets for further exploration and evaluation are identified.关键词
