Abstract: It is an unconventional means of oil and gas exploration to use radioactive elements to search for oil and gas. In recent years,sandstones with high natural gamma (GR) value (100-300 API) have been drilled in Paleogene around the hydrocarbon-rich depression in Zhuyi Depression,Pearl River Mouth Basin,and the GR value is even higher than that of mudstone in the same area(100-200 API). In order to understand the geological significance behind this special phenomenon,the correlation trend line analysis of the contents of uranium (U), thorium (Th) and potassium (K) with GR value was carried out for the Paleogene sandstone with high GR value in Pearl River Mouth Basin. The main reasons and genetic mechanism of the increase of GR value of sandstone were analyzed from the characteristics of well seismic,lithology and mineral composition,and the accumulation conditions,migration channels,driving forces and hydrocarbon significance of radioactive elements were discussed. The results show that the GR value of sandstone is higher in Xijiang and Huizhou areas due to the increase of U content,and higher in Enping and Panyu areas due to the increase of K and Th content. There are two genetic mechanisms for the increase of GR value of sandstone. One is that the enrichment of radioactive element ion U4+ brought by underground fluid at oxidation-reduction surface leads to the high GR value of formation. This special phenomenon shows that the enrichment of U4+ indicates the existence of oil and gas in traps near large faults with connected basement,which confirms the effectiveness of oil and gas migration channels in the study area and has very important guiding significance for the prediction of oil and gas reservoirs. The other is that the massive deposition of minerals containing radioactive elements brought by surface fluids leads to the high GR value of strata and unstable properties of minerals containing radioactive elements,which can indicate the existence of near-source supply,and is of great significance for judging the provenance and sedimentary environment. The research results provide a basis for predicting favorable zones for hydrocarbon accumulation in the study area.

Key words: sandstone with high natural gamma value, radioactive element, granite, Paleogene, Pearl River Mouth Basin
