    摘要
  • 南海北部琼东南盆地具有准被动大陆边缘性质,其深水区具有较好的勘探前景。综合利用地震、钻井等资料,从层序地层研究出发,探讨了等时地层格架内新近系储层沉积特征,总结了浅水(陆表海)背景和深水(陆坡)背景下的储层沉积模式。根据储盖层沉积背景,并结合已有钻井资料,指出深水区新近系主要发育深水沉积和浅水沉积两大类型储盖组合:浅水背景储盖组合,包括梅山组-三亚组低位扇砂体+浅海相泥岩、梅山组生物礁灰岩+深海相泥岩;深水背景储盖组合,包括莺歌海组-黄流组浊积水道砂体+深海相泥岩、莺歌海组高位三角洲砂体+半深海相泥岩。在此基础上,提出了储层预测模式,并对其进行了初步评价。
    The Qiongdongnan basin, northern South China Sea is a quasi passive continental margin in terms of its tectonic characteristics. There are favorable exploration perspectives in the deep-water area of the basin. According to the principle of sequence stratigraphy, integrated interpretation of depositional characteristics of reservoirs and reservoir-cap combinations in the Neogene has been made based on high resolution seismic data and well data. In the study area, there occur two types of reservoir-cap combinations in the Neogene sequence, one formed in the shallow water environment (the Epicontinental Sea) and the other in deep water environment (the Continental Slope). Depositional models for both the shallow water deposits and the deep water deposits were established in this research. The reservoir-cap combination formed in the shallow water environment include lowstand sandstone of the Meishan Formation or Huangliu Formation, shallow marine mudstone, organic reef limestone of the Meishan Formation and deep water mudstone, whereas the reservoir-cap combination formed in the deep water environment include turbidite channel sandstone of the Huangliu Formation or Yinggehai Formation, and deep water mudstone, highstand deltaic sandbodies of the Yinggehai Formation.. Upon the study mentioned above, a reservoir prediction model was proposed and preliminary evaluation has been made.
