STUDY ON THE QUANTITATIVE MODEL FOR POINT BAR OF MODERN MEANDERING RIVER
-
摘要: 利用卫星照片测量了全球27个典型现代曲流河点坝的规模参数,对曲流河点坝的沉积特征参数进行了半定量到定量的研究,建立了曲流河点坝的长度、宽度与河流满岸宽度之间的定量关系式,并探讨了应用于曲流河相储层研究的思路.Abstract: By measuring the geometric parameters of 27 typical point bars of modern meandering river from satellite photographs, the sedimentary characteristics of point bar are studied from quantitatively or semi-quantitatively. The quantitative relation between the length, width of point bar and bankfull width of river is established. This result can be applied in the research for oil reservoir of meandering facies.
