摘要
干热岩作为一种新型的地热资源,其勘探与开发有重要意义.本文将对干热岩国内外勘探与开发现状进行介绍,给出寻找干热岩的勘探思路.结合已有的地质与地球物理资料对松辽盆地地热分布和地球物理特征进行分析.松辽盆地在地质、地球物理和地球化学等方面已有了大量的研究,通过对本地区的磁法和重力数据进行处理,进行莫霍面、居里面等界面的深度反演,计算不同深度的地热温度值及梯度值,总结分析区域的干热岩形成的条件,圈定可能的尚未开发研究的存在干热岩的区域,并给出了初步的评价结果.
The prospecting and development of hot dry rock（HDR）,a new type of geothermal resources,are getting more and more important.There are a lot of research achievements on basis geology,hydrogeology,geochemistry and geophysics of Songliao Basin.In this paper,the current situation of prospecting and developing the HDR will be introduced.The way of prospecting HDR will be given.Combined with geology and geophysics data,through the processing of the magnetic and gravity data,the Moho surface and Curie interface will be given.Then we calculate the geothermal change at different depths.Finally we summarize and analyze the characteristics of the gravity and magnetic data and conclude to delineate the areas that possibly have the hot dry rocks.The evaluations of these areas are also given.
