摘　　要：介绍了井温、噪声组合测井找漏原理及其适应条件。井温、噪声组合找漏测井在龙岗气田2口环空带压气井的首次现场应用结果表明,在渗漏量较大时,通过井温测井能明显检查到井温异常段,结合噪声点测资料能准确找到渗漏点;在渗漏量极小的情况下,通过多方技术分析,综合噪声点测结果,能找到正确的渗漏点位置;井温、噪声组合找漏测井方法寻找漏失点效果明显,可为气井下步治理方案及制定相应的控制措施提供依据,具有推广应用前景。Combined temperature and noise the logging is one of conventional tools used in locaing tubing leakage and casing leakage. The principle and required conditions of combined noise and temperature logging is analyzed. First field application of combined temperature and noise logging in two gas wells of Longgang field shows when gas leakage is larger the logging together with noise spot measuring data can easily detect the leakage; when gas leakage is smaller the log- ging may exactly detect the leakage with the help of technology analyses and the noise spot meas- uring data. Combined temperature and noise logging provides the basis for establishing corresponding control measures of gas well. And it has a wide range of application and promotion prospects.
