| 摘 要： | 运用地震沉积学基本原理,借助高分辨率三维地震数据体,综合使用三维可视化、相干体解释、地层切片技术、地震分频与RGB混频等技术手段对哈拉哈塘地区某三维地震区的古河道进行识别和刻画.精细刻画出志留系底界面与奥陶系吐木休克组底界面2个重要沉积间断期发育的河道体系并总结其特征.研究结果表明:志留系底界面发育高曲度的稳定曲流河,而吐木休克组底界面发育典型的曲流河.两期河道发育期哈拉哈塘地区均处于相对平缓的地貌背景.通过古河道的识别可知:在吐木休克组沉积前该区域曾发生短暂暴露性沉积间断而非传统认识的直接发育的淹没台地型水下沉积间断,从而为吐木休克组底界面下发育的古岩溶储层提供更合理的成因背景解释. |

| Abstract: | According to the basic principle of seismic sedimentology,using high-resolution 3D seismic,comprehensively applying 3D visualization,coherence cube interpreting,stratigraphical slicing method,seismic frequency-decomposition and RGB frequency mixing,paleo-channels in Halahatang area were recognized.Characteristics of paleo-channels on the bottom of Silurian and Tumuxiuke formation of Ordovician were depicted.The results show that paleo-channels on the bottom of Silurian belong to stable meandering and ones i... |
