6. Conclusions
- Based on drilling data, field outcrops evaluations, thin section analysis, and 3D seismic data, Wensu low paleo-uplift was discovered in the Keping–Wensu area of the Tarim Basin. The planar distribution of the Wensu low paleo-uplift is typically demonstrated as a SW–NE trending nose structure, characterized by a far SW-trending extension, a narrow NE-trending extension, and an overall characteristic of being higher in the west and lower in the east.
- At the end of the Sinian period, the Tarim plate was uplifted as a whole, and Nanhuan–Sinian formations were denuded in the whole basin due to the influence of the Keping movement. In the Early Cambrian, the Tabei paleo-uplift evolved into the Wensu low paleo-uplift, which basically died out in the Middle Cambrian.
- In the Early Cambrian, the Wensu paleo-uplift controlled the development of high-quality source rocks in the Yurtusi Formation. The contemporaneous paleotectonic framework also controlled the formation of mound-shoal complexes and grain shoals, laying the foundation for high-quality reservoirs in the Xiaoerbulak and Wusonger Formations. Effective source–reservoir–cap assemblages were developed in the paleo-uplift area, constituting two sets of effective hydrocarbon accumulations in the upper and lower stratigraphic parts of the basin. The upper assemblage holds greater exploration potential, and is expected to be a next strategic target area for hydrocarbon exploration of Cambrian subsalt in the Keping–Wensu area.
