一、前言 相对振幅保持地震剖面正在准噶尔盆地西北缘的地震资料解释工作中普遍使用。如何对相对振幅保持地震剖面进行可靠的地质解释从而达到直接找油找气的目的就成为一个迫切需要解决的课题。 我们知道反射振幅与反射系数成正比例变化。反射系数是储集层与盖层速度和密度的函数。储集层的速度和密度的变化除了同岩性有关外,还同含烃类与含水不同而变化。这也是“亮点”技术的物理基础。
I. INTRODUCTION Relative Amplitude Preservation Earthquake profiles are commonly used in seismic data interpretation in the northwestern margin of the Junggar Basin. How to reliably interpret the relative amplitude of the seismic profile to achieve the purpose of finding oil directly is an urgent issue to be solved. We know that the reflection amplitude is proportional to the reflection coefficient. The reflection coefficient is a function of the velocity and density of the reservoir and cover. Changes in reservoir velocity and density, except for lithology, also vary from hydrocarbon to water. This is also the physical basis of “bright spot” technology.
