根据声测井得出的速度分布统计特征,给出了多层构造反射系数序列的自相关函数形式。在反射系数强度不太大的条件下,导出存在于速度分布统计特征与多层构造反射传递函数之间的一种简单关系。据此,对目前常用的线性地震拟测井处理过程进行了具体分析,指出畸变恒不可免;在此基础上,提出了实际处理中力求减小畸变的可能途径。
According to the statistical characteristics of velocity distribution obtained by acoustic logging, the autocorrelation function of multi-layer structure reflection coefficient sequence is given. Under the condition that the intensity of the reflection coefficient is not too big, a simple relationship between the statistical characteristics of the velocity distribution and the reflection transfer function of the multilayer structure is deduced. Based on this, a detailed analysis is made of the commonly used linear seismic well logging process, pointing out that the distortion can not be avoided. On this basis, the possible ways of reducing distortion are put forward.
