中文摘要	对银-额(银根-额济纳旗)盆地以石炭系二叠系为主要目的层开展了油气地质调查实施的7条大地电磁测深剖面资料的处理和定性分析,在综合信息反演和成像的基础上建立了重磁电综合反演剖面图。以钻井、地震和区域地质调查资料为约束条件,确定了电性层标定和解释的基本原则。利用大地电磁测深反演电阻率低阻标志层,准确地界定了中生界的埋深和厚度,次高阻层半定量地刻画出了石炭系二叠系的分布,对剖面的地质层位进行了追踪划分,对研究区地层、电性特征进行了系统的总结。研究成果表明,大地电磁测深法是获取中生界、古生界分布的重要手段。在银-额盆地复杂地质条件和沙漠区恶劣的施工条件下,大地电磁测深法显示出的优势和良好的勘探效果尤为明显,在该区石炭系二叠系油气地质调查中起到了重要作用。
英文摘要	Based on data processing and qualitative analysis of seven magnetotelluric sounding profile,take Carboniferous-Permian as the main purpose layer,the authors implement oil gas geological investigation in Yingen-Ejin Banner basin.We have established seven gravity magnetoelectricity comprehensive inversion profile drawing in the synthesis information inversion and formation of image.Taken the well drilling,the seismic and the regional geology investigation material as the constraints,we have determined the electrical layer demarcation and the explanation basic principle.We have accurately decided the Mesozoic strata of buried depth and thickness using low resistivity marker accurate boundary of the magnetotelluric sounding inversion electronic resistivity,the second high-lever resistance layer semi-quantitative depicted Carboniferous-Permians distribution.We have divided the section plane geological horizon,and summarized systematically the strata and electrical characteristics in the research area.Research results show that magnetotelluric sounding is an important way to obtain distributed characteristics of Mesozoic and Paleozoic.In Yingen-Ejin Banner basins complex geology and desert area bad working conditions,magnetotelluric sounding demonstrated the good exploration effect and the obvious superiority,played the influential role for Carboniferous-Permian oil gas geological investigation in this area.
