摘要
针对准噶尔盆地玛湖凹陷玛东地区多物源条件下不同扇体控制的砂体叠置关系复杂的情况,以玛东地区多个三维地震测网形成的连片三维地震数据体的构造解释成果为基础,将玛东地区三叠系百口泉组古地貌与坡折带分布特征相结合,厘清了该区多物源的形成条件和古构造特征;采用地震波形分类方法,实现了该区百口泉组不同小段的多物源不同扇体发育边界及其相互关系的识别与预测,并综合地震属性、地震反演的砂体预测方法,综合分析认为,玛东地区三叠系百口泉组多物源下不同扇体的扇三角洲前缘砂体纵向复杂叠置、横向连片但不连通或呈现点状独立的分布特征。
Aiming at the complex relationship among the sand bodies controlled by different fans under the multi provenance conditions and 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 inter vals 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 distri bution.
