摘要 

为了研究鄂尔多斯盆地西南缘基底特征,利用2016年在该地区获取的1∶5万高精度航磁资料和已有的1∶20万重力资料,推断了地壳断裂1条、基底断裂11条及中央古隆起的南部范围。采用重磁联合反演,大致了解了区内基底和盖层的埋深和厚度。应用欧拉反褶积和场源参数成像,分别用重力数据和航磁数据提取了区内奥陶系顶面的埋深信息和基底的埋深信息。研究表明:利用高精度航磁资料结合重力资料能够相对有效地识别基底特征。

Abstract

Based on the aeromagnetic data of the latest high precision of 1∶50 000 and the existing gravity data of 1∶200 000 in 2016 in the southwestern margin of Ordos Basin, data processing was carried out. 1crust fault, 11 basement faults,3 cap rock faults and range of the southern central uplift. Using joint inversion of gravity and magnetic data the depth and thickness of basement and cap rock is roughly understood. The analysis indicates that the gravity field mainly reflects the difference in density between the Ordovician and its overlying sedimentary cover, and the magnetic field mainly reflects the structure of the crystalline substrate. Combined with joint inversion of gravity and magnetic data, the top surface depth of the Ordovician system and the crystallographic basement depth were extracted respectively using gravity data and aeromagnetic data by Euler deconvolution and source parameter imaging, and the basement lithofacies were studied. All that provided an important basis for the prediction of oil and gas in the area. The study believes that the use of high-precision aeromagnetic data combined with gravity data can identify base features effectively and make up for the lack of other geophysical data.
