采集了巴彦浩特盆地火成岩及其它岩类露头、岩心、岩屑标本,并测定和分析了它们的物性特征;利用联合反演技术对地面高精度磁测资料和重力资料进行了反演解释;并对大地电磁测深资料与重磁资料进行了综合解释。得出了火成岩分布范围,为部署参数井提供了重要依据。钻探结果证实了地球物理综合解释的正确性.

We have sampled outcrops, cores and cuttings for igneous rocks and other rocks in Bayanhaote basin, and measured their physical properties. Joint inversion is performed on surface high precision magnetic and gravity data. The distribution of igneous rock that is one of foundations for deployment of well position is resulted from integrated interpretation of magnetotelluric, gravity, and magnetic data The integrated interpretation of geophysical data is confirmed by drilling results
