摘要
依据烃类微渗漏理论，综合采用遥感、化探、微磁、放射性及地温等多种技术方法，在塔里木盆地进行了油气藏烃类的地表检测试验及特征分析。检测结果显示，油气藏上方存在着较强的烃类微渗漏及其蚀变效应，表现为地表高浓度烃类异常、微磁及放射性的边缘异常、高地温异常及地物波谱曲线异常。根据异常特征分析，建立了塔里木盆地油气藏上方烃类微渗漏的地表效应模式。
Based on the theory of hydrocarbon microseepage, many surface detection methods can be used in Tarim basin, which includeremote sensing, surface geochemistry, micromagnetics, radioactive and temperature measurement. The features of surfacehydrocarbon detection are high hydrocarbon density, rim micromagnetic and radioactive anomalies, high temperature andspectral curve anomaly, based on which, a surface effect model of hydrocarbon seepage over the oil and gas reservoirs ofTarim basin has been built up.
