沉积物热释光能有效地反映海洋环境下深部油气田引起的微弱放射性异常。热释光在不同的测试粒级、不同的岩性中的丰度不同 ,结果为粗粒级 >细粒级、砂岩 >粉砂质砂岩 >泥质粉砂岩 >泥岩。热释光也与部分金属元素含量有关 ,Ti、Ba、Zn、Fe3+ /Fe2 + 与热释光呈正相关关系。热释光与烃类也呈较强的正相关性。不同采样深度热释光测量结果表明 ,热释光剂量随沉积物的沉积深度和沉积时间的增加而增加 ,深层样的热释光对油气藏的指示效果更好
Sediment thermoluminescence can effectively reflect the weak radioactive anomalies caused by deep oil and gas fields in the marine environment. The thermoluminescence is different in the test grain size and the abundance in different lithology. The result is coarse grain grade> fine grain grade, sandstone> silty sandstone> argillaceous siltstone> mudstone. Thermoluminescence also related to the content of some metal elements, Ti, Ba, Zn, Fe3 + / Fe2 + and the thermoluminescence was positively correlated. Thermoluminescence and hydrocarbons also showed a strong positive correlation. The results of the thermoluminescence measurements at different sampling depths show that the thermoluminescence dose increases with the deposition depth and deposition time of the sediments, and the deep-layer thermoluminescence has a better indication of the reservoir
