Currently, in the oil-field exploitation, existing the phenomenon of garbling the lack thickness of stratum with vertical fault-throw in well logging identification of strata while meeting fault in drilling well. In most case, consider the lack thickness of stratum which contrast the imperfection geologic strata thickness to the well and the well as the fault-throw. The method which using very popular in oil-field exist shortages, it very much easily lead people into the areas of misplay. especially when the seismic person and geology confirm the fault-throw, It often appear inconsistent instance.

目前，在油田开发中钻井钻遇断层时，地质人员时常存在将测井分层与相邻井对比时缺失地层厚度与铅直地层断距混淆的现象，很多情况下把井与井对比缺失地层厚度等同于断层断距等，这些现今在油田非常流行的用法存在一些不足之处，容易把人们引入一些认识上的误区，特别是在地震与地质人员进行断层断距的确定时，经常出现矛盾的情况。

Based on the equal strain consolidation model of sand drain ,and neglecting the well resistance and the vertical drainage consolidation,a layered model for the nonlinear consolidation of sand drain ,which accounts for the geostatic pressure varying along depth and the relationship between the average viod ratio and the logarithm of average effective stress,is presented.
