Satic shift in magnetotelluric is a common phenomenon that wi11 lead tolarge error in interpret and determine the nature of the model of the data. Now,scholarsin every country are trying to find the method of correcting static shift.In this paper,after briefly narrating the five major kinds of method about correcting static shift,theauthor willgive details on how to correct static shift by the method of coinciding head partof apparent resistivity curve. The author puts forward the principle of choosing referencefreqency. The real position of resistivity curve is calcualated with equal weightingcoefficient orthogonal polynome. The author presents a method about how toautomatilally distinguish the parallel shift in apparent resistivity curve and its form. Byanalysing the static shift removed data,We know that the static shift is in every where.It is possible that there is no static shift in the deposit centre of basin;Although there aremany kinds of form of parallel shift,but the main form is ρ_(TE) curve with upward shiftρ_(TM) curve with down ward shift,and the ρ_(TE) curve is above the ρ_(TM) curve. The ρ_(TE) curve is similar to ρ_(TM) curve in easiness to parallel shift.

着重论述如何用首枝重合法校正静态效应。提出用等权正交多项式拟合视电阻率曲线真实位置;指出了选择参考频率的原则;以及如何自动识别是否有静态效应的影响,产生了何种形式的静位移。分析静校正处理后的资料可知,静态效应影响几乎无所不在,但在盆地沉积中心有可能无静位移情形;静位移的形式是多样的,但主体形式是ρ_(TE)曲线向上,ρ_(TM)曲线向下位移,且ρ_(TE)曲线在ρ_(TM)曲线之上;ρ_(TE)曲线与ρ_(TM)曲线基本上一样容易产生静位移。

The residual static correction plays a very important role in seismic data processing. Toobtain reasonable results,it is necessary to trace the correct reflection zones and to pick ac-curate time shifts between traces. A commonly used method is the correlation method.If the signal-to-noise ratio is relatively low, it is often necessary to choose one more reasonable re-sult from two completely different ones.A wrong choice may seriously distort the seismicprofile. This is the so-called multiple value problem....

The residual static correction plays a very important role in seismic data processing. Toobtain reasonable results,it is necessary to trace the correct reflection zones and to pick ac-curate time shifts between traces. A commonly used method is the correlation method.If the signal-to-noise ratio is relatively low, it is often necessary to choose one more reasonable re-sult from two completely different ones.A wrong choice may seriously distort the seismicprofile. This is the so-called multiple value problem. Wavelet Packet is a new method of sig-nal processing, It can split a signal into many pieces,with different infomation carried bydifferent pieces. The pure signal may be stored in some special pieces,If this is true,a puresignal can be extracted just by picking out these special pieces. A preprocessing method forseismic data is developed based on the said ideas. Numerical experiments show that the mul-tiple value problem is well solved.

强反射层追踪与相对时差拾取中的“多值”现象严重影响剩余静校正的效果,为此提出的小波包预处理方法,可以实现地震道噪声与信号及不同强反射层的分离,从而能自动识别并提取“纯”的强反射层,提高强反射层追踪的可靠性和相对时差的拾取精度.

The generality of this method is briefly introduced in this paper. The general residual statics equation can be related to the Radon transform by a 2 - D integrable function to define the distributions of the residual statics terms, the structure term and the residual NMO term all together. Therefore, the residual statics terms can be found by applying the inverse Radon tromsform. A few sets of theoretic data are processed by the Radon transform method and the results are compared with those calculated by the...

The generality of this method is briefly introduced in this paper. The general residual statics equation can be related to the Radon transform by a 2 - D integrable function to define the distributions of the residual statics terms, the structure term and the residual NMO term all together. Therefore, the residual statics terms can be found by applying the inverse Radon tromsform. A few sets of theoretic data are processed by the Radon transform method and the results are compared with those calculated by the general linear inversion method. The comparison between the two methods shows that higher precision can be reached by the Radon transform processing.

对剩余静校正的Radon变换方法作了简要介绍.当用二维可积函数统一定义剩余静校正量项、构造项和剩余动校正量项的各项分布时.可以把广义剩余静校正方程同Radon变换联系起来,因而应用Radon逆变换就可以反演出剩余位静正量项.用Radon变换方法对几组理论数据进行处理,并与广义线性反演剩余静校正方法比较,结果表明应用Radon变换在一般的剩余静校正问题中可以得到精度更高的剩余静校正量.
