Abstract：The occurrence cause of fault in seismic section is analysed in the aspects of data acquisition,data processing and data interpretation. The author points out that the fault interpretation in seismic section may be indeterminate, false and soluble in several ways;and so is the geologic fault interpretation which is based on seismic fault interpretation. Forward modeling has proved that fault interpretation in seismic section may be indeterminate,false and soluble in several ways. It can be seen from these that the faults- in seismic section are different but correlative to the geologic faults. Applying seismic sections to geologic structure interpretation,sedimentary facies interpretation,oil sources interpretation and hydrocarbon trap evaluation,geologists must know the relation between, seismic fault interpretation and geologic fault interpretation,otherwise they will draw mistaken conclusions.
