Abstract:

The petroleum resource assessment implemented by the PetroChina Company Limited shows that there are still lots of remaining petroleum resources and considerable exploration potential in Jiuquan Basin.Three major exploration areas were determined,including the over-thrust belt of the south of Jiuquan Basin,the lower salience in oil-rich sag as well as the lithologic and structural-lithologic oil reservoirs around the slope of the basin,the strike-slip faulted structural belt in the west of the basin.Of the three major exploration areas,the over-thrust belt of the south of basin is the most important exploration area.

Key words: petroleum resource assessment, exploration potential, exploration field, over-thrust belt, Jiuquan Basin

摘要：

中国石油天然气股份有限公司第三次油气资源评价表明,酒泉盆地剩余油气资源丰富,具有较大的勘探潜力.盆地的3大主要勘探领域是盆地南部冲断带;富油凹陷内部低凸起以及环凹斜坡带岩性及构造-岩性复合性油气藏;盆地西部走滑断裂构造带.其中,盆地南部冲断带是近期最主要的勘探领域.
