英文摘要 | Deep-water mound-shaped sediment packages on the northern slope of the Xisha carbonate platforms in the northern South China Sea were analyzed by integrating high-resolution multi-channel seismic and drilling data. The mounds are distributed in the Beijiao depression of the Qiongdongnan Basin within the T41-T40 seismic horizons, which correspond to the middle Miocene. Mound-shaped reflections were identified both in the NE-SW and NW-SE oriented seismic profiles. The mound shapes are most prominent in the center of the NW-SE oriented seismic profiles, and the undulating tops flatten out towards the NW and SE. Similar reflections are mostly asymmetric, with steeper eastern flanks in the NE-SW oriented seismic profiles, and they are mostly round in shape. The wave impedance from the inversion calculation is 6-8 x 10(6) kg/(m(2).s). It is much lower than that of the reef reservoir in the LH11-1 Reef Oilfield. Paleogeographic analysis shows that the Xisha uplift was dominated by tropical shallow carbonate platforms, while the Beijiao depression became a bathyal environment in the middle Miocene. Drilling data confirmed that the mound-shaped sediment packages are mainly composed of calcareous mudstone. Therefore, we infer that the mound-shaped sediment packages could be reef complexes or they were presumably built by combined gravity flow and bottom current. (C) 2015 Elsevier Ltd.
