对山东临南油田137．5km2的594件土壤样品的磁性特征进行了分析研究，发现油气田上方磁性异常比较复杂。在本区的土壤磁性异常多表现为高值环带包围低值区块的环带异常，并且见油钻孔多分布在中低值区内，显示土壤磁性异常与油气储集之间存在一定的对应关系，虽然不精确，但大多数见油钻孔分布于土壤磁性异常低位区内。
The magnetic characteristics of 594 soil samples from 137.5km2 in Linnan Oilfield in Shandong Province were analyzed and the magnetic anomalies above the oil and gas fields were found to be complex. In this area, the anomaly of the soil is mostly characterized by the anomalous zone anomaly surrounded by the high-value zone and low-value areas, and the oil boreholes are mostly distributed in the middle-low zone, indicating that there is a certain relationship between the soil magnetic anomaly and the hydrocarbon accumulation Although not accurate, most of the oil boreholes are found in the low magnetic anomalies of soil.
