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.
