S/N ratio of seismic data in Yidong huge faulting system and buried hill structure In Sicou area is very low, because of complicated geologic structure, heterogeneous distribution of offsets in old observation systems, narrow azimuth and the small fold number. As a result, it is difficult to provide accurate structure interpretation and oil deposit description using the data. The paper aimed at complicated geologic structure designs an adopting accurate target seismic acquisition and a series of high precision acquisition techniques in practical field production. Based on these , the whole level of data quality in target area can be improved largely and the seismic sections can be used in accurate structure interpretation. The fact that this method has been used successfully in the area shows that the method is efficient to solve bad data problem in complicated geologic structure area and has reference value to similar area.
