摘　　要：　在运用声波时差法计算76口钻井的地层剥蚀量的基础上,利用地层对比法以钻井的地层剥蚀量为起算点和约束点,以相交剖面在交点处的剥蚀厚度相等为原则,计算全区的地层剥蚀量,恢复江陵凹陷N/E间断面地层剥蚀厚度,为研究区的构造演化史、沉积发育史和生排烃史的深入研究提供依据。Based on the calculated erosion by means of acoustic moveout from 7b wells,the amount of erosion of the entire depression was calculated and the erosion thickness of hiatus surface from the Neogene to Eogene was restored in reference to the stratigraphic correlation in the Jiangling depression.

关 键 词：地层剥蚀厚度 计算方法 江陵凹陷 N/E间断面
