摘　　要：为了克服单一地震属性研究复杂地质问题所产生的误差,应用地震影像学原理,通过多种地震属性融合将影像由一维线性变为三维空间,提高了岩相的成像精度,减少了地震属性的多解性。应用地层岩相影像技术精细刻画了贝西斜坡南屯组地质体的三维轮廓和有利储层的分布,认为在西部物源控制下的贝西斜坡发育扇三角洲—湖底扇—深湖、半深湖沉积体系。该技术的预测结果符合地质规律,与钻井结果的吻合度较高。To overcome the error generated by single seismic attribute studying complex geology problem, the seismic image is changed from 1 D to 3 D by integrated multiple seismic attributes applied by seismic imageology principles; the imaging precision of lithofacies is enhanced and the ambiguity of seismic attributes is reduced. 3D geologic configuration and distribution of beneficial reservoirs in Nantu Formation of West Beier Slope are finely described by stratigraphic lithofacies imaging technique. The study shows that fan delta-sublacustrine fan-deep lake and semi-deep lake sedimentary systems are developed in the slope controlled by the western source area; the predicted results is accordant with geological laws and consistency with the drilled achievements is pretty higher.
