摘　　要：河流相等时地层单元的划分与对比一直是困扰石油地质工作者的难题。基于河流相野外露头资料,并利用虚拟井测井曲线正演结果对目前常用的河流相对比方法的精度进行了分析。研究结果认为,对于河流相而言,在遵循地层划分对比储层层次分析法的基础上,顶面等高程法是河流相小层或单砂体对比较为有效的方法;同时,井距越小,对比精度越高。The classification of fluvial facies isochronic strata units was a problem puzzled petroleum geologists.Based on outcrop data,and forward modeling results of virtual well logging were used and the accuracy of current correlation method for fluvial facies was analyzed.The result indicates that for fluvial facies,on the basis of hierarchy analytical method of stratigraphic classification,top surface equal altitude method is still an effective way for the classification of fluvial facies strata or single sand body,in addition,it also indicates the smaller the well space is,the higher the accuracy of contrast is.
