东北漠河盆地北部冻土分布特征
Permafrost distribution characteristics of northern Mohe basis in Northeast China
摘要
Abstract
Mohe basin has favorable reservoir-forming prospect for gas hydrate,and the understanding of the permafrost development situation in the basin is very important for evaluation of gas hydrate resources potential and optimization of favorable areas.One of the purposes of carrying out audio frequency magnetotelluric sounding profile measurement in Mohe area of Northeast China is to find out the buried depth and spatial distribution of permafrost in the working area.Based on an analysis of the electrical property characteristics and high resistivity features of the permafrost,the authors made thickness recognition and division.The exploration results show that the permafrost in northern Mohe basin exhibits island-shaped distribution,with characteristics of thick in the north and thin in the south,thin in the west and thick in central and east parts,with the maximum thickness being 120m and the average thickness being 40～80,which demonstrates that the study area has favorable permafrost conditions for the formation of gas hydrate resources.关键词
