先验信息约束静校正技术及应用
|
摘要
依托于地震工程数据库平台,在现有静校正方法的基础上,提出一种新的静校正技术———先验信息约束静校正技术.该技术充分利用各种已成熟或接近成熟的技术,综合各种地质和地球物理数据,通过点、线、面一体化的表层交互分析解释方式,调整建立符合当地区域地质特征的表层结构模型,利用模型法静校正公式算出每个接收点和炮点的静校正量,最终静校正量由模型静校正量约束折射或层析校正量所得.这样就实现了正确构造背景下高精度成像,同时也为解决表层静校正问题提供可选择的静校正技术手段.实际应用表明,该方法和技术对DCZ地区大量的地震数据是适用的和有效的,在该区的地震勘探中解决了一定的问题并取得了一定的效果.
Based on seismic engineering database platform and the existing static correction method,a novel static correction technique-static correction technique constrained by prior information is put forward.The technique uses various matured or nearly mature techniques and various geological and geophysical data,the surface structure model accordance with local regional geology feature is established by the interactive analysis and interpretation of point,line and surface.The static correction of every receiving points and shot points using the static correction formula in model method,and the final static correction is obtained by the constrain refraction of model static correction or tomographic correction.So the high precision imaging is realized under correct structural background,and at the same time,an optional technologic means is provided for solving surface static correction.The application of the technique in DCZ area shows that it is effective.
