Abstract: Abstract: 〖WT5BZ〗The Luojiazhai area in northeast Sichuan Basin is dominated by the geologic bodies with high mountains, highsteep complex structures and anisotropic geologic medium, where 2D and 3D narrow azimuth prospecting would not meet the seismic requirements, the fine interpretation is needed urgently. Through research for years,and the analysis of the characteristic and difficulty of wide azimuth 3D prospecting in high mountains, a set of seismic technique, i.e, mountainous wide azimuth 3D acquirement technique, with observing system of midpoint shot, 8×5 folds, line distance 400m, mini shotreceiver distance 565.7m, max shotreceiver distance 4216m, wide azimuth 3D processing technique with 3D floating datum plane, tomography static rectification, series migration in the velocity field, 3D interpreting technique based on wave equation forward, multiwell restrict backward, poststack fissure detection for seismic attribute and wide azimuth 3D reservoir predication technique, has been integrated and applied with the satisfied results obtained in Luojiazhai area in northeast Sichuan.
Key words: mountainous, wide azimuth 3D, prospecting technology, Luojiazhai area
