摘要
该文介绍了采用微测井方法来进行近地表结构调查工作。同时结合人工踏勘、观察岩石露头、岩性录井、含水性调查等方法综合确定近地表结构,了解工区内低、降速带厚度和速度分布特征,分析表层地震地质条件的变化,为确定井深提供依据,也可为静校正数据库提供精确的数据。
This paper introduces that the micro logging method is used to investigate the near-surface structure. Meanwhile,combined with the comprehensive method of artificial reconnaissance,observating the rock outcrop,lithology logging,aquosity surveying and so on to determine the near-surface structure,to understand the thickness and velocity distribution in the low velocity zone and deceleration zone,and to analyse the changing of the geologic conditions of surface seismic,these method provide the basis for determining the well depth,and these methods also provide the accurate data for static correction database.
