【摘要】 冻土区勘探一直是地震探测的一个难点.为了探测研究区的深部结构,分析可能的天然气水合物的分布情况及其冻土区地球物理响应特征。我们在研究区进行了高精度的二维地震勘探试验.本文主要介绍针对冻土区的地震资料野外采集技术试验方法,包括资料的静校正问题、冻土层反射成像问题及精细速度分析等.通过对这些试验结果的分析,作者总结出一套针对高原冻土区,地形起伏变化较大的地震野外施工方法和静校正方法,为今后类似地区的地震勘探及其他物探方法,提供了参数设置依据和一些经验.更多还原

【Abstract】 Cryolothozoneexploration has always been a difficulty of seismic exploration.The paper uses the highprecision 2d seismic exploration,in order to detect the deep structure of study area and the distribution of feasible gas hydrate and geophysical response characteristics of cryolithozonedetaliedly,The paper mainly introduces acquisition technology of seismic data in cryolithozone,including the problem of static correction,tundra reflection imaging and elaborate velocity analysis,et al.Through these aspects,we summarize the methods of seismic exploration and static correction for plateau area and the area of terrain ups and downs changed.It can provide the basis of parameter and some experience for the future of seismic exploration and other geophysical exploration methods in the area.更多还原
