沙丘离散法野外静校正在塔中地区的应用研究
|
摘要
针对塔里木盆地表层结构变化剧烈的特点,根据观测水坑法精确计算潜水面深度,建立近地表模型,利用沙丘离散法计算静校正量。对应用观测水坑法和小折射法的不同静校正结果进行了对比。应用表明,采用观测水坑法建立近地表模型,并利用沙丘离散法计算的野外静校正量,获得了较好的应用效果。
In consideration of the characteristics of rapid changes of surface structures in Tarim Basin, based on a water-pit observing method, subsurface depth is calculated, a near surface model is established, amount of static correction is calculated by using a dune dispersion method. The results from water pit observing and from short-refraction are correlated. Application shows that a near surface model is established by using water-pit observing method with its medium as continuous one, and the dune dispersion method is used to calculate the amount of field static correction with a good result of application.
