| 摘 要： | 利用木里煤田聚乎更矿区四井田、哆嗦公马和雪霍立三个矿区53个孔的测井资料对该煤田季节冻土（岩）、多年冻土（岩）厚度、底（顶）界深度及分布特征进行研究,确定了季节冻土（岩）、多年冻土（岩）在井温曲线上的2种形态：＂U＂型及＂L＂型,并对其影响测井解释精度的因素进行了分析。根据简易井孔测温解释成果,绘制了3个区的多年冻土（岩）层等厚度三维图,总面积达72.54k㎡。三个研究区多年冻土（岩）厚度三维示意图显示,多年冻土（岩）在这3个井田内均有分布,在空间上呈连续似层状分布,但厚度变化较大。

| Abstract: | Using well logging data from 53 boreholes in three mine areas of the 4th minefield of Juhugeng,Duosuogongma and Xuehuoli in the Muri coalfield,carried out thicknesses,floor（roof） depths of seasonal frozen soil（rock） and permafrost distribution features.The study has determined 2 patterns of them on temperature curves： ＂U＂ type and ＂L＂ type,and analyzed factors affecting accuracy of well logging interpretation.According to facility well temperature logging interpretation results,has drawn 3D permafrost isopach of the three areas with total area 72.54km2.The 3D schematic isopaches have demonstrated that there are permafrost in the three minefields,their distribution is spatially continuous quasi-bedded with rather abrupt variation of thicknesses. |
