在地形变化、低速带厚度变化和表层速度变化剧烈的地区从事地震工作,若不作“静校正”,是无法进行地震资料基本处理和解释的,如:速度的求取、各种迭加……。目前,国内研究“静校正”的单位还不多,江汉油田曾利用共深度点道集研究静校正值的提取,并取得了宝贵的经验。从国内外介绍的资料来看,提取“静校正”值的方法很多,但我们对这些方法都缺少实践,这次试验只是根据四川的一些特点,如:山势陡峭、低速带变化大,地下速度值高……选用了在“共一炮点”和“共一接收点”平面上提取静校正值。为了弄清静校正的各种影响因素,合理和正确地应用方法,我们首先用理论模型对方法进行了试验,下一步应把方法推广到实际资料中去。本文主要介绍在 In the terrain changes, low-speed zone thickness changes and surface velocity changes rapidly violent earthquake work, without “static correction” is unable to carry out the basic processing and interpretation of seismic data, such as: the speed of access, all kinds of superimposed ... ... . At present, there are not many units studied in China for “static correction”. Jianghan Oilfield has used the common depth point set to study the extraction of static correction values ​​and has gained valuable experience. According to the data presented at home and abroad, there are many ways to extract the “static correction” value, but we all lack practice on these methods. The experiment is based on some characteristics of Sichuan Province, such as steep mountain slopes, large changes in low-speed zones, High speed ... ... selected in the “one shot” and “a total receiver point” plane to extract static correction. In order to find out the various influencing factors of static correction and to apply the method rationally and correctly, we first test the method with the theoretical model. The method should be extended to the actual data in the next step. This article focuses on
