| 摘 要： | 本文介绍了ＤＺ地区应用氡管法、α径迹法、地面γ能谱法及水中铀含量测量等放射性方法探测天然气藏的依据和效果。根据放射性测量资料，圈出了ＤＺ地区油气放射性异常（带）。对比结果表明：这些异常分布在地震勘探圈定出的ＤＺ鼻状隆起上，后者被钻探结果证实为含天然气的构造，有力地说明放射性方法探测天然气藏的有效性。最后，根据放射性异常分布特征和地质资料，总结出断鼻天然气藏的放射性异常模式。

| Abstract: | This paper introduces the fundamentals and effectiveness of various radiometric methodsincluding the Rn tube method,a track method,surface gamma-ray spectrometric method andthe method of determining U contents in water. According to radiometric survey data, oiland gas radioactive anomalies(zones) have been delineated in DZ area. The results fromcomparison show that these anomalies spread over a DZ nose delineated by seismic survey,which has been confirmed to be a gas-bearing structure by drilling. This provides strong evidence on the effectiveness of radiometric methods applied to natural gas exploration.Meanwhile the pattern of radioactive anomalies related to a broken nose type gas reservoir are established based on the distribution feature of radioactive anomalies on DZ gas-bearing structure and corresponding geological data. |
