Based on study of seismic geometry in the large obstacle in the Sanxingdui heritage conservation area, this paper presented change-the-view methods of combination of multi-variable technique. The basic ideas are to use the technique of regular layout and layout of additional receiver line and to design a optimal seismic geometry after the designed geometry to do repeat adjustment and the folds of observation layout variation technique are used. The issues of effective receiving and shooting in safety way going through the larger obstacle in the Sanxingdui heritage conservation area were successfully solved by the technique and ensured data proper acquisition of seismic data for target layer. One example in MJIII blocks of 3D seismic data acquisition with achieving ideal results was presented.
