摘　　要：长期以来,江陵凹陷油气勘探以深层新沟嘴组和白垩系为重点,对荆沙组地层未作系统分析与评价,其基本成藏条件研究不深入,勘探潜力不明确。近期沙26-8井在荆沙组的钻探取得重大突破,明确荆沙组具有一定的成藏条件,使得荆沙组成为研究重点和储量增长新的勘探目的层。For a long time,great attention has been paid to the deep layer of Xingouzui Formation and Cretaceous system in oil-gas exploration in Jianglin Depression,and systematical analysis and assessment on Jingsha formation neglected.So full research on its basic reservoir forming condition has not been accomplished,thus making exploration potential uncertain.Major progress has been made in recent drilling of Sha 26-8 well in Jingsha Formation.This shows that Jingsha Formation is provided with a certain reservoir condition,which makes it become major studying object and new exploration target for increasing reserves.
