摘要
概述了当前石油地震勘探中薄层研究的下列主要方面:关于薄层的标定,主要方法有垂直地震剖面法、理论合成记录法、平均速度法和多档滤波法;薄层厚度求取的主要方法有:相对振幅—时间厚度法、间接振幅法、反射波特征点法、积分振幅与视时差乘积法、窄带滤波法以及标定曲线法和振幅谱能量等方法;薄储集体圈定及横向预测,主要着重于由界面型剖面向岩层型剖面转换方法的研究,如:地震岩性模拟技术、合成声波测井等方法。
This paper discusses the following three aspects of thin bed studies main in today's oil seismic exploration: demarcation of thin bed (including vertical seismic section, theoretical synthetic seismogram,average velocity and multiple filter wave methods); estimation thin-bed thinckness(including relative amplitude-time thinckness, indirect amplitude, seismic reflection characteristic-point, product of integral amplitude and the apparent interval travel time, narrow band filter wave, demarcation curve and amplitude spectrum energy methods); enclosing and lateral predicting of thin reservoirs (including convertion of seismic reflection section into lithologic logging section, for example, seismic lithologic imitation technique and synthetic sonic logging method).
