多参数约束高分辨率处理方法在东濮凹陷中的应用

Application of multiparameter-constrained high resolution processing method in Dongpu Depression

多参数约束高分辨率处理方法的基本思想是充分利用已知的测井、地质、地震资料的信息，在它们共同约束下，去求取一个具有较高分辨率和较宽频带的近似反射系数序列剖面。利用该方法对东濮凹陷部分实际地震资料进行了处理，取得了明显的效果，使地震记录的主频提高、频带展宽约3倍左右，并且处理后剖面的交点基本闭合，从而说明该处理方法是目前在室内提高常规地震记录分辨率的有效方法。

The basic idea of the multiparameter-constrained high resolution processing method is to make full use of known well logs, geological and seismic data to derive an approximate reflectivity series section with high resolution and broad bandwidth, We apply this method to process real seismic data from Dengpu Depression and achieve obvious effects, The dominant frequency and bandwidth of seismic records increase by about three times and the points of intersection after processing are closed in the main. These show that the method is effective for improving the resolution of conventional seismic records indoors at present.
