运用地面和航空伽马射线谱测量寻找赋存在地层和构造圈闭中的石油矿产这一新的勘探方法已研究成功。使用钍归一化处理方法对钾和铀数据进行改正可压制岩性和环境因素所造成的干扰。在油田上方，归一化钾显示出低值特征，而归一化铀相对于钾而言则在油田上显示出高值特征，在油田之外显示低伍特征。笔者把异常形成的原因归结为微生物吸收微渗透碳氢化合物的结果。对涉及美国６个州和７０６个油气田的航空伽马射线谱数据的研究结果表明，其中７２．７％的油气田上有归一化钾和铀异常显示。同时，在研究区２６００ｋｍ￣２范围内新发现２７个未经证实的类似异常。在美国，包括阿拉斯加和澳大利亚大量的潜在油气田区都有航空伽马射线谱测量数据。对澳大利亚两个盆地的初步试验也表明，放射性异常区与已知油气田有正相关关系。自从１９８８年以来，笔者对地表放射性数据的研究配合土壤碳氢化合物和土壤磁化率测量在得克萨斯州Ｃｏｎｃｈｏ县发现了４个油气田。
The new exploration method using ground and air gamma ray spectroscopy to search for petroleum minerals present in strata and structural traps has been studied successfully. The correction of potassium and uranium data using the thorium normalization method can suppress the interference caused by lithology and environmental factors. Above the field, normalized potassium showed low values, while normalized uranium showed high values on the field relative to potassium and low level on the field. The author attributed the abnormal formation of micro-organisms absorb the results of micro-infiltration of hydrocarbons. The results of the study on the airborne gamma ray data of six states and 706 fields in the United States show that 72.7% of the fields have normalized potassium and uranium anomalies. In the meantime, 27 unidentified similar anomalies were newly found in the study area of 2600km ~ 2. In the United States, aeronautical gamma ray spectrometry data are available in a large number of potential oil and gas fields, including Alaska and Australia. Preliminary tests of two basins in Australia also show that there is a positive correlation between the radioactive anomalies and known oil and gas fields. Since 1988, I have discovered four oil and gas fields in Concho County, Texas, for the study of surface radioactivity with soil hydrocarbon and soil magnetic susceptibility measurements.
