当前世界,氡测量法(包括瞬时测氡和积累测氡)新进展表现为:累积测氡法的灵敏度不断提高;氡测量仪器的标定装置逐渐在一些发达国家建立;氡的迁移机理的深入研究;测氡仪的微机化,直读氡含量。 氡测量法在地质中的应用也越来越广泛,表现为如下几方面: 1、勘查油气 氡法勘查油气的模式,一是直接探寻与油气矿床伴生的铀的衰变子体~(222)Rn;二是寻找与油气矿床相关的构造。美国在丹佛盆地六七千米以下的油气田上方作氡法填图圈出了油田的边界。我国地矿部第六物探队和物探研究所采用累积测氡法探查石油也取得了效果。
In the current world, the new progress of radon measurement (including instantaneous radon measurement and accumulation measurement of radon) is as follows: the sensitivity of cumulative radon measurement is increasing; the calibration device of radon measuring instrument is gradually established in some developed countries; and the further research on radon migration mechanism ; Measured radon computerized, direct reading radon content. The application of radon measurement in geology is also more and more widely, which is manifested in the following aspects: 1. Prospecting oil and gas by radon prospecting model, one is to directly explore decay progeny of uranium associated with oil and gas deposits, (222) Rn ; The second is looking for structures related to oil and gas deposits. The United States conducted a radon mapping above the oil and gas fields less than 67 kilometers in the Denver Basin to circle the fields. China’s Ministry of Geology and Mineral Resources 6th Geophysical Prospecting Institute and the cumulative measurement of radon method used to explore the oil also achieved results.
