摘要: 酒西坳陷石大凹陷为一东断西超的中新生代箕状断陷湖盆。在凹陷陡坡带主要发育了独具特色的近岸水下扇砂岩沉积体。这种类型的砂体常常下切到深湖–半深湖暗色泥岩,具有自生自储的特点,成藏条件优越,具有较好的勘探前景。

Abstract: The Shida sag in Jiuxi depression is a Mesozoic-Cenozoic halfgraben-like basin with faulting in east and overlap in west. In the steep slope belt of Shida Sag, there deposited some submarine fan sandbodies. The sandbodies often sinked into the hemi/deep lacustrine dark mudstone and featured both source and reservoir in them. So, the hydrocarbon accumulation conditions are superior with great potentials for exploration.

Key words: submarine fan, sedimentary feature, lithologic reservoir, Shida sag, Jiuxi depression
