江汉盆地内GC油田的地表为沼泽地。本文介绍在该油田应用氡管法，α卡法、α径迹法等土壤氡法圈定油气藏的效果的试验研究工作。结果表明，在沼泽地区，由于氡管法的测量装置避免了积水的影响，取得满意的地质效果。氡管法施工轻便，工作效率也比较高，适合于沼泽地区油气普查与勘探。
The surface of GC oilfield in Jianghan Basin is wetland. This paper introduces the experimental research on the effect of radon delineation of oil and gas reservoirs by radon method, α-card method and α-track method. The results show that, in the swamp area, due to the radon tube measuring device to avoid the impact of water, to obtain satisfactory geological results. The radon pipe method has the advantages of light construction and high working efficiency, and is suitable for the oil and gas census and exploration in the swamp area.
