【摘要】 以高分辨率层序地层学、旋回地层学理论为基础,以邯郸盆地第四系钻孔HZ-S、HZ5-3为例,探索了应用地震纵横波速综合参数识别层序地层界面进而划分层序的方法。根据波速参数随地层深度变化的曲线在层序界面附近存在的突变点或拐点,对HZ-S钻孔剖面进行了详细的四级、五级层序界面识别和对应层序的划分,并与岩心、测井、孢粉资料的分析结果进行对比,显示了很好的一致性,进一步通过HZ5-3钻孔的分析结果验证,表明应用地震纵横波速综合参数可以识别层序地层界面,进而划分地层。更多还原

【Abstract】 On the basis of the theories of High-Resolution Sequence Stratigraphy and Cyclo-Stratigraphy,to take the Quaternary bores named HZ-S and HZ5-3 in Handan Basin,the application of using comprehensive parameters of the velocity of seismic P-wave and S-wave to identify sequence boundaries and subdivide sequences is discussed.The nearby-sequence-boundary abrupt-change-points and inflexions of parametric curves,on which the values of comprehensive parameters of the velocity of seismic P-wave and S-wave change with the depth of strata,are used to make detailed boundary identification and corresponding stratigraphic subdivision of fourth-order and fifth-order sequences for the stratigraphic profile of the bore named HZ-S.And the result is accordant with the analysis results of the core,well-logging and cryptogam data from the same bore when compared with each other.Further verification through the analysis result of another bore named HZ5-3 shows that comprehensive parameters of the velocity of seismic P-wave and S-wave can be used to identify sequence boundaries and subdivide sequences.更多还原
