摘要： Aiming at the complex relationship among the sand bodies controlled by different fans under the multi-provenance condition sand based on the structural interpretation results of the contiguous 3D seismic data formed by several 3D seismic survey networks in the Madong area of the Mahu sag, Junggar basin. The paper clarifies the forming conditions and paleo-tectonic characteristics of the multiple provenances in the area on the basis of structural interpretation and paleo-geomorphic analysis of the Triassic Baikouquan Formation in the Madong area; performs identification and prediction of the fan boundaries and their relations with multiple provenances in different intervals of the Baikouquan Formation in the Madong area by using seismic waveform classification method. Using seismic attribute and seismic inversion prediction methods, the authors comprehensively analyze the distribution of the sand bodies in the fan delta fronts of different fans and conclude the features of complex superimposition vertically and continuity but disconnection laterally, or spot-like isolated distribution.
