摘　　要：近几年 ,车西北部古潜山带的勘探获重大突破 ,发现了太古宇、下古生界、上古生界等多层系的古潜山油气藏 ,油气藏类型有风化壳型、古潜山内幕型。该区古潜山地质结构、成藏条件分析表明 ,被下第三系覆盖的车西北部古潜山带是油气聚集的主要单元之一 ,不同的构造单元具有不同的油气分布特征 ,而储集条件控制了油气富集高产。古潜山油气藏多与第三系油气藏上下叠置 。In recent years, a great breakthrough has been made in exploration of buried hill in the north of Chexi. Buried hill reservoirs have been discovered in Archaean, lower Palaeozoic, and upper Palaeozoic. The types of these reservoirs include weathering crust and inner buried hill. Analysis of geological structure and reservoir forming conditions shows that, the buried hill zone covered by Palaeogene in the north of Chexi is one of the major units of oil and gas accumulation. Different structural unit has different features of oil and gas distribution. Oil and gas accumulation was controlled by reservoir conditions. Buried hill reservoirs are most likely superimposed with Tertiary ones, forming complicated oil and gas reservoirs.
