摘要
溱潼凹陷是一个经多年勘探的新生代沉积凹陷，石油勘探程度较高，天然气勘探程度相对较低。通过对凹陷内浅层储层、盖层特征、天然气气源条件及各种类型的浅层构造圈闭的分析研究，结合钻孔资料，揭示了凹陷内浅层天然气在纵向上、平面上的分布规律，对凹陷内浅层天然气的勘探前景作出适当评价。
The Qintong depression is a Neozoic sedimentary one which have been explorated for many years with very high exploration degree on petroleum and relatively lower exploration degree on gas. Through various researches and analysis on the shallow reservoir, features of cover, condition of source gas as well as each type of shallow structural trap, combined with drilling results within the depression, the paper reveals the shallow gas of distribution law on both of vertical and plane directions, and evaluated properly the prospecting future of the shallow gas in the depression.
