摘　　要：目前常用的古地形、地貌研究方法大多基于地层古厚度恢复,建立在沉积后"填平补齐"的基本假设之上。因此,古地形恢复的精度主要取决于地层古厚度恢复的精度和对"填平补齐"的基本假设的校正。古地形、地貌的研究在油气勘探的多个领域已经发挥了积极地作用,但仍然存在很多的问题值得思考,需要通过不断实践进一步解决。立足于三维地震资料,应用沉积学原理开展古地形、地貌研究是未来一个重要的发展方向。仅就在利用三维地震资料进行古地形恢复中需要面对的几个问题作针对性的讨论,希望能给从事相关研究的工作者一些启发。At present, the common research methods of the paleogeomorphy are mostly based on the recovery of the ancient thickness of the strata and the basic assumption for filling the gaps after deposition. Therefore, the preci- sion of the recovery of paleogeomorphy mainly depends on the accuracy of the recovery of the ancient thickness of the strata and the correction of the basic assumption for the filling the gaps. The findings of paleogeomorphy and paleogeomorphic have played a positive role in many fields of oil and gas exploration through many years of research, but there are still many problems that are worth constantly thinking and practicing to solve. It is an important direction of the future development to carry out the paleogeomorphic research that based on 3D seismic data and applying deposition principle. Utilizing 3D seismic data, this article aims to make targeted discussions about some questions in the recovery of the paleogeomorphy, hope to be able to bring some inspiration for the researchers engaged in relevant research.
