通过对鄂尔多斯盆地南部测量剖面73个大地电磁测深点资料的处理,将各点的测深曲线进行了归纳分类,探讨了曲线类型的电性层划分与地质属性的关系。在MT资料处理解释的基础上,对模型作了二维正演计算,同时又对测区的重磁异常作了进一步的处理,并结合地质、钻井资料进行了综合地质与地球物理解释,对查明该地区的地电结构、沉积特征、深部构造和断裂展布以及基底性质提出了新的认识。
By processing the data of 73 geomagnetic sounding points measured in the southern part of Ordos Basin, the sounding curves of each point are summarized and classified into categories, and the relationship between the distribution of electrical layers and the geological attributes is discussed. Based on the explanation of MT data processing, a 2D forward modeling calculation is made for the model. At the same time, the gravity and magnetic anomalies in the survey area are further processed. Comprehensive geophysical and geophysical interpretation is made based on the geological and drilling data. A new understanding of the geoelectric structure, sedimentary features, deep structure and fracture distribution and the nature of the basement has been identified.
