摘要
依据油田和油田水中的氡气含量比地壳和地表空气高5~6个数量级,氡气常沿油气田周边微细裂隙和油(气)水边界向上运移的特点,应用美国产RAD7型电子测氡仪先在四川盆地磨溪、麻柳场气田上进行了氡气测量,在气田周边发现的环带状氡气异常与钻探证实的气水边界基本吻合,而后在新疆准中盆地永进地区利用氡气测量法圈定的油(气)水边界和油气田范围也较好的反映实际地质情况,取得了较好的找油气效果。
Radon gas measurement was carried out in gas fields of Moxi and Maliuchang in Sichuan basin applying RAD7-type electrical radon gas meter made in America,based on the characteristics that the radon concentration in oil field and oil field water is 5 to 6 order of magnitudes than the average crust and surface gas,with radon gas usually transported along minute fissures and oil(gas)-water boundary around oil and gas field.The ring-shaped radon gas anomaly found around gas field basically coincides with gas-water boundary testified by drilling.The following application of radon gas measurement in Yongjin area in central Junggar basin in Xinjiang for outlining oil(gas)-water boundary and oil(gas)field also received good result for oil(gas) exploration,reflecting real geological conditions in the area.
