航空和地面综合地球物理方法开展干热岩探测研究
|
摘要
通过讨论干热岩对其附近岩层磁性和电性的影响,结合磁法和大地电磁法勘查的发展现状,提出了利用航空和地面综合地球物理方法开展干热岩勘探的思路设想,即利用航磁测量、航空天然场电磁测量(ZTEM)及大地电磁测量(MT)综合方法互相配合、优势互补,利用磁化强度矢量反演得到地下三维磁化率分布特征模型,利用印模法将ZTEM与MT数据有机结合起来,得到较大面积的地下三维视电阻率特征模型,磁电综合分析,实现快速勘探干热岩,加快我国开发和利用新型清洁能源——地热能的步伐。
Through the discussion about the hot dry rock'influence on the magnetic and electrical properties of rock layers nearby,combining with the development status of magnetic and electromagnetic exploration,therefore we put forward tentative ideas to carry out hot dry rock exploration using airborne and ground geophysical methods.In other words,the synthetic application of aeromagnetic survey,Z-Axis Tipper Electromagnetic(ZTEM) survey and magnetotellurics(MT) can cooperate with and complement each other.Using the magnetization vector inversion,the three-dimensional model of magnetic susceptibility distribution is obtained.The ZTEM and MT data are combined by the stamping method to obtain the characteristic model of three-dimensional apparent resistivity i underground.The comprehensive analysis of magnetoelectricity,in this way,can achieve rapidly dry rock exploration and speed up the development and utilization of new clean energy(geothermal energy) in China.
