摘　　要：利用地层厚度对比法、用相对剥蚀量代替绝对剥蚀量的方法恢复了鄂尔多斯盆地东南部的4期剥蚀量。同时,用回剥法恢复了目的层的古厚度和古埋深,编制了单井埋藏史图和目的层在关键变革期的古构造图,并探讨了演化特征及对页岩气成藏的地质意义,对指导该区的进一步勘探开发有重要意义。The erosion amount during the 4 periods in the southeast of Ordos Basin is restored by using formation thickness correlation methods and relative denuded thickness as the replacement of absolute denuded thickness.Meanwhile,paleostructure formation thickness and buried depth of the target formation are restored by using back denudation thickness methods and buried depth history map and paleostructure map in the key period of revolution for a single well are plotted.The paper also studies the evolution characteristics and its geological significance to shale gas formation.The study is significant for guiding the further development of the area.
