航磁三分量向上延拓在判断地质体物性参数上的应用研究
|
摘要
2017年我国研制出了航磁三分量测量系统,但对于三分量数据的解释与应用还处于探索阶段。笔者从磁法三分量数据向上延拓的公式推导入手,首次获得了三分量数据的向上延拓理论公式。随后设计了以模型中心埋深、模型体积、深/浅部模型的磁化强度、模型顶面埋深、模型间距为变量的立方体组合模型,获得了滤除异常所需的最低延拓高度与物性参数之间的对应关系,并总结得到了一定的规律。最后将总结的规律应用于实测三分量数据中,结合测量区域的地质状况做出了相应的解释,获得较好的结果。
China developed the aeromagnetic three-component measurement system in 2017; nevertheless,the application of the threecomponent data is still in the exploratory stage. At first,the authors derived the upward continuation formula of magnetic three-component data and obtained the formula for the first time. Then the authors designed cube combinational models,with depth of center point,volume,magnetization in different depths and depth of top surface as the variables. The relationship between minimum continuation height and physical parameters was obtained. In addition,the authors summarized some laws from these models. Finally,these conclusions were combined with the actual aeromagnetic three-component data. According to the geological condition of the survey area,the interpretation was made and good results were obtained.
