摘要: 通过对琼东南盆地钻井及典型地震相分析,认为琼东南盆地深水区发育两种类型的储层:第一类为形成于浅水环境的储层,包括扇三角洲砂体、滨浅海相滩坝砂体和台地碳酸盐岩;第二类为形成于深水环境的储层,包括盆底扇和峡谷水道等低位砂体。其中,深水区广泛分布的海底扇、峡谷水道砂体和台地碳酸盐岩具有良好的深水油气勘探潜力。

Abstract: Two types of deep-water hydrocarbon reservoirs are recognized on the basis of boreholes and seismic facies analysis in the Qiongdongna Basin, South China Sea. Type 1 reservoirs are formed in the shallow-water environments including the fan delta sandstones, littoral-shallow marine beach/bar sandstones and platform carbonate rocks, and type 2 reservoirs are originated from the deep-water environments including basin-floor fan and canyon channel sandstones. The submarine fan and canyon channel sandstones and platform carbonate rocks widespread in the deep-water areas are believed to be highly prospective for the deep-water hydrocarbon exploration.
