摘要

应用土壤磁化率结合化探、地震、遥感资料，在内蒙西部荒漠区进行大面积油气勘查的综合研究，结果表明土壤磁化率异常与烃异常有相似的分布趋势，并都受构造控制。根据两个含油气局部构造磁化率异常与磁性矿物含量分析结果，认为磁化率异常的成因是由于含油气构造部位次生磁性物质形成的总体效应所致，因此，应用此方法进行油气勘查，只能作为一种烃蚀变异常的间接指示指标
Using soil magnetic susceptibility combined with geochemical,seismic and remote sensing data,the authors made an integrated study of large area oil and gas exploration in the desert region of western Inner Mongolia.The results show that the soil magnetic susceptibility anomalies are similar to hydrocarbon anomalies in distribution trend,both controlled by structure.Based on analytical results of magnetic susceptibility anomalies and magnetic mineral content in two oil and gas bearing local structures,it is held that the magnetic susceptibility anomalies result genetically from overall effects of secondary magnetic materials at the oil and gas bearing structural positions.Therefore,the application of this technique to the oil and gas exploration can only serve as an indirect indicator of the hydrocarbon alteration anomaly.
