摘要
在深部地质找矿中,利用多条电测深剖面组建三维测网,建立了电阻率三维反演坐标系统,实现了快速电阻率三维反演,为快速了解测区地层电性特征和钻孔布设提供了依据。通过对新疆哲兰德萨依金铜矿区多条不等距测深剖面电阻率三维反演试验,证明快速电阻率三维反演适合沿走向延伸不大的二度半或三度体,试验深度达400m。显示了其在矿产物探中的应用效果。
In the deep geological prospecting,three-dimensional surveying networks were constructed using multiple electrical sounding profiles,and a three-dimensional resistivity inversion coordinate system was established to realize rapid three-dimensional resistivity inversion.To quickly understand the electrical characteristics of the formation in the survey area,drill holes The layout provides the basis.The three-dimensional resistivity inversion test of multiple unequal sounding profiles in the Zhelander Sayi gold-copper mining area in Xinjiang proves that the rapid three-dimensional resistivity inversion is suitable for two-and-ahalf or third-degree bodies that do not extend along the trend.The depth is up to 400 m.It shows its application effect in mineral exploration.
