Minimum Entropy Deconvolution (MED-Western Geological Company of America Service Mark) was developed to aid the extraction of detailed reflectivity information from amplitude anomalies in reflection seismic recordings. Interpreting such reflectivity information depends on accurate compensation for the combined effects of the source wavelet and earth filtering. MED approaches this problem by finding a linear operator that maximizes the "spike-like" character of a representative set of traces. Uulike predictive deconvolution, the MED process makes no assumptions about the phase characteristics of the "seismic wavelet",nor does it assume that the reflection series is white-certainly a poor assumption over short-time windows where "bright spots" dominate. Rather than seeking to whiten data, the MED process seeks the smallest number of large spikes that is consistent with the data.

最小熵反褶积(简称MED)主要是用来从反射地震记录的振幅异常中提取尽可能详细的反射讯息,解释这些反射讯息需要对震源子波及地层滤波的复合效应作精确的补偿。最小熵反褶积实质上就相当于求解这样一个问题,这就是要找出一个线性算子,该算子能使我们所选用的道集中尖脉冲的特性能最大限度地得到加强。与预测反褶积不同,最小熵反褶积不需要对地震子波的相位特性作任何假定,也不需要假定反射序列是白噪序列——事实上,这种假定对于“亮点”占绝对优势的短时窗来说,是没有什么实际意义的。最小熵反褶积主要在于找出与实际资料相符的大尖脉冲的最小数目而不是去寻找白化资料。 合成资料的例子说明,可以根据未叠加道同相轴间非常微小的时差,利用最小熵反褶积的方法,确定出有效的算子。在使输出道尖脉冲得到加强的过程中,最小熵反褶积算子将有选择地对那些相干讯号与随机干扰的比率比较低的频率进行压制。对于存在亮点的反射区域来说,这种压制干扰的性能使未经叠加的输出道特别适合于用来分析与偏移距有关的各种变化。

In this paper, the possibility of recovering the ampli tude from the sign bit record is proved by the analysis of noise. The method and effect of sign bit horizontal stack is also introduced. Some experiments show that the sign bit horizontal stack method emphasizes the coherence of reflections, thus weak reflections on the section are enhanced. It is pointed out in this paper that with the development of the sign bit technique,methods which were considered too difficult to employ in the past may be taken advantage...

How the formation dip, velocity scan parameters and coherence determination affect velocity analysis accuracy is specially discussed on the basis of summing up traditional velocity analysis methods. The designed velocity scan interval Δν must be made to accord with scan accuracy standard. The velocity analysis accuracy may be raised by applying iterative stacking method and multiplying model trace stacking method to common-range gathers. The multiplying model trace stacking method is much more superior than other methods because of more concentrated effective energy in shallow and middle formations, rather concentrated energy in deep formation of a velocity spectrum (i. e. less "flat arm effect" ) and convenient computation etc.

基于传统的速度分析方法,着重讨论了地层倾角、速度扫描参数及相干性测量给速度分析精度带来的影响。在设计速度扫描间隔△v时,要力求符合扫描精度标准。采用同炮检距道集进行迭代叠加和乘模型系数道叠加,可以提高速度分析的精度。乘模型系数道叠加法较其他方法有更大的优越性,这主要表现在浅中层有效反射的能量更集中、深层的“平臂效应”减少、便于计算等方面。
