横波微地震测井资料处理方法探索及初步应用
|
摘要
在地震勘探施工中,如何准确获取低降速带变化规律,建立合理的表层结构模型,进而确定合理的激发因素,求取准确的静校正量,获得更好的地质剖面极为重要。横波微测井是一种简便、快速、准确的近地表测试技术。利用横波微测井技术进行表层调查已经发展了多年,在一些探区进行了试验和方法攻关,取得了较好的效果。文章主要简述了横波微地震测井的现场施测技术、处理解释方法原理等,井结合调查实例,简述横波微地震测井方法在胜利东部探区的应用,将其解释结果与其他表层结构调查资料进行对比说明其应用效果。
It's very important to gain the rules of the high-speed layer alternation,build an advisable near surface model,define the rightful shooting parameter,account the accurate measurement update and so on.The S-wave microseismogram log is a simple,fast and accurate ground test technology.This article briefly introduces the operating procedure as well as processing principle and method for the the S-wave microseismogram log technology.Combined with the examples of the LJ area,it summarizes this method in the eastern Shengli exploration area and shows the contrast of the explanation results with those of other method to show the application effect.
