摘要
通过在秦王川盆地中部地区开展地球物理勘查,结合地面地质调查,已知钻孔录井、测井等资料,采用音频大地电磁测深二维反演技术和Petrel 3D可视化技术,建立秦王川盆地中部地区视电阻率参数下的3D地质模型.模型依据视电阻率变化和地层岩性之间的相互关系,精细刻划地下地质体结构,从3D立体结构上精确描述了地下岩石的电性响应特征,揭示了秦王川盆地中部地区第四系基底埋深分布规律.
Combined with surface geology,the existing boreholes and well logging,an apparent resistivity model have been built based on the two-dimensional inversion technique of audio magnetotelluric sounding and the Petrel three-dimensional visualization technology through geophysical exploration in the central part of the Qinwangchuan Basin.The electrical response characteristics of the underground rocks have been described accurately from the three-dimensional structure according to the relationship between apparent resistivity values and rock lithology,and the basement depth of Quaternary system has been found out as well.
