摘要(Abstract):
在河流相储层研究中,关于河流及点坝构型的研究侧重于剖面和平面,且多以定性研究为主,已有的基于露头和现代沉积的经验公式不足以指导利用地下井资料建立点坝三维构型模型。对现代河流沉积地貌的数据统计分析结果表明,对于弯曲度大于1.7的曲流河段,河流宽度和点坝长度之间有一定的正相关性,由此建立了二者之间的函数关系,进而为地下曲流河废弃河道三维预测及点坝砂体构型的分布规模提供依据,指导曲流河点坝地下储层构型的定量分析。
In the study of fluvial facies reservoir,the structure types' studies of rivers and point bars emphasize cross section and horizontal plane and furthermore takes qualitative study as main form,the existed empirical formulas based on outcrop and modern sedimentation are not enough to guide the modeling of 3 D point bar with the help of underground well data.The data statistics and analysis of the sedimentary morphological shape for modern rivers show that for meandering river reach with tortuosity factor more than 1.7,there is a certain direct correlation between river width and point-bar length,so the function relation of the above two can be established,and furthermore provide the evidence for the distribution laws of the abandoned river channel 3 D prediction of underground meandering river and the structural type of point-bar sand body,in the end guide the quantitative analysis of reservoir structure's type of the point bar of meandering river.
