摘　　要：利用频谱激电法在青海沱沱河地区进行天然气水合物勘查,确定天然气水合物的赋存地层和深度,并探讨天然气水合物的在沱沱河地区的赋存特点,为沱沱河地区天然气水合物的勘查,提供了可靠的地球物理依据,为探测常年冻土层的厚度提供了一种有效的地球物理方法。This paper deals with the basic principles and technical method of the application of spectrum induced polarization method to gas hydrate exploration. The method was used to determine the occurrence and depth of gas hydrate in the Tuotuo River region. Several electrical property parameters can be obtained by the use of the spectrum induced polarization method. The exploration depth of this method is large. This method provides reliable geophysical basis for the exploration of gas hydrate and an effective geophysical technique for detection of the thickness of the permafrost layer in the Tuotuo River region.
