The Jiyuan depression is the hydrocarbon-bearing area discovered eariiest in North China.Terribly complicated seismic-geological con- dition and very heavy multitudinous noises result in very low signal /noise ratio of seismic data in this area,which severely obstructed hydrocarbon exploration in this area.Hence,research of seismic me- thods for this area has been made systematically.Reasonable seismic data acquisition parameters were determined by making detailed surface -layer analysis and overall field tests,and by designing expert system with the use of spectral analysis data and field operation data.Conse- quently,special field method(including deep shot hole,big array leng- th,high stacking fold and high low-cut filtering)was adopted to imp- rove raw seismic data obviouslyo Furthermore,good static correction, correct stack velocity and reasonable prestack two-dimensional filtering were used to remove seismic noise in data processing.The above me- thods can improve signal/noise ratio and result in qualified seismic data which favour structural and lithologic interpretations.

济源凹陷是华北地区最早发现油气显示的老区。由于该区的地震地质条件极其复杂,地震噪声类型多、强度大,导致地震资料信噪比极低,严重阻碍了该区的油气勘探。为此,在该区系统地进行了地震方法研究。首先进行了精细的表层研究工作和系统的野外参数试验,并利用大量的频谱分析资料和野外工作参数设计专家系统,正确地选择地震采集参数。然后由野外试验最后确定了以强化组合法和“两高、两大” (即大井深、大组合基距,高叠加次数、高低截滤波)为特征的野外工作方法,明显提高了地震资料质量。在资料处理中,要认真作好静校正,求准叠加速度,合理利用叠前二维滤波,才能有效地消除地震噪声。通过上述措施,提高了地震资料信噪比,获得了能用于构造解释和地震地层学解释的资料。

The robust least squares(LS) single source method can be used when there is uncorrelated electric noise but requires noise free magnetic time series, or vice versa. The robust remote reference method can also be used when there is uncorrelated noise both in the electric and in the magnetic time series. While there is not any method being able to obtain unbiased estimates of...

The method for obtaining unbiased estimates of the transfer function depends on the type of noise presenting in the various time series. The robust least squares(LS) single source method can be used when there is uncorrelated electric noise but requires noise free magnetic time series, or vice versa. The robust remote reference method can also be used when there is uncorrelated noise both in the electric and in the magnetic time series. While there is not any method being able to obtain unbiased estimates of the transfer function when there is stronger correlated noise both in the electric and in the magnetic time series. The history of magnetotelluric method is firstly reviewed, and then the methods for estimation of response function in frequency or time domain, including those were widely used or tested numerically, are introduced and discussed. Some advances for estimation of response function are concluded at last.

从本质上来说,能否得到大地电磁响应函数的无偏估计,取决于实测电磁场时间序列中所含噪声的类型和强度。当磁场时间序列不含噪声且电场仅含不相关噪声时,单站RobustLS方法是有效的;当磁场和电场时间序列同时含有不相关噪声时,Robust远参考方法也是有效的;但当磁场和电场时间序列含较强的相关噪声时,已有的方法已无能为力。文中在简要回顾大地电磁法的发展历史之后,对国外估计大地电磁响应函数的方法作了较全面的总结和评述,并着重介绍了几种值得关注的新方法。应该指出,受欢迎的方法必须兼顾估计的精度、稳定性和野外工作效率。
