摘要

基于钻孔数据的多层DEM构模技术是构建沉积环境下三维地层模型的有效方法，但该方法对在河流的侵蚀和淤积交替作用下形成的地层建模效果并不理想。针对这种缺陷，对传统的建模流程加以改进，充分考虑到河流侵蚀作用对地层的切割影响，在建模的过程中对地层层面进行了两次插值与高程调整，使在钻孔附近地层的尖灭处理更为自然与合理。应用实例表明，该方法的建模结果非常接近于实际地层分布情况，从而验证了该方法的可靠性。

Abstract

Multi-DEM approach

which is based on borehole data

is flexible

speediness and effective for sedimentary formation; but it is not suited for stratigraphic system controlled by fluvial erosion and aggrading action. To solve this problem

a significant improvement over the previous workflow is presented. Considering fluvial erosion action

interpolation and adjusting of horizon elevations were done two times; so it is natural and reasonable to the pinching of strata around boreholes. The effectiveness and flexibility of the approach are proved by a case study.
