氡录井的HSE和油气地质意义

HSE and petroleum geological significance of radon logging

该文在石油工程中首次提出了氡录井的概念。氡的致癌危害已被世界公认,根据已有的油气地面化探资料,首先从HSE的角度,分析阐述了氡录井的意义和价值,从国内外已有的资料上看钻井井场存在很高的氡暴露风险,应当依法进行氡录井。从油气地质的角度,随钻氡监测可以获得极有价值的地质信息,氡的异常高值常与地壳中油气储集相伴生,其放射性检测值在油田边界处呈现高值,断层处也多呈现高值;上述特性对油气藏的预测与发现提供另一手段和途径。氡录井不是简单的仪器测氡,而是兼顾HSE和油气地质分析的复杂技术,是录井工程的创新点和新的经济增长点。

The paper first put forward the concept of radon logging in petroleum engineering. The carcinogenic hazard of radon has been widely recognized. According to the existing oil and gas surface chemical data, the authors set forth from the point of HSE to analyze and clarify the significance and value of radon logging, seen from the available data at home and abroad, there is a high risk of radon exposure at drilling wellsite, thus radon logging should be carried out in accordance with the law. From the perspective of oil and gas geology, radon monitoring while drilling can obtain the valuable geological information, the abnormally high values of radon are often associated with the storage of oil and gas in the earth′s crust, which are followed by radioactive detection value showing high values at the sides of oilfields and faults showing high values as well; the above characteristics can provide another means and ways for the prediction and discovery of hydrocarbon reservoirs. Radon logging is not a simple instrument to measure radon, it is a complex technique that accounts of HSE and the analysis of oil and gas geology, which is a new mud logging engineering innovation and economic growth point.
