大地电磁测深成果与地质剖面联合解释及其效果

Combining interpretation on the result of magnetotelluric sounding with the geology and the effect

为了解雪峰山西侧地区的深部构造特征,促进对油气勘探有利区段的选取,通过总结大地电磁测深模型正演计算成果特征,对大地电磁测深(MT)资料进行分析与研究,并结合测区的地质和物性特征,对研究区的断裂、褶皱、地层展布进行了分析。在此基础上,预测了油气勘探有利区段。预测结果与油气地质中有油气显示区域基本一致,为该区下一步勘探提供了基础资料。

To understand the characteristics of the deep structure about the western side of the Xuefeng mountain and to promote the selection of petroleum exploration strategic areas, the authors through summarizing the forward modeling char- acteristics of megnetotelluric（MT） sounding technology and combined with the geological characteristics and physical proper- ties of the area to analysis the magnetotelluric（MT） sounding data, the faults, folds and subsurface stratigraphic distribu- tion. Based on the above analysis, forecasted the favorable area for petroleum exploration, and the prediction is almost the same with the geological information, so it provides basic data for further exploration in the area.
