摘　　要：南海东部珠江口盆地番禺某区块为气测值低、荧光显示不明显等的复杂油气藏,现场常规录井很难准确识别油气显示。介绍了地化热解气相色谱技术的分析原理、评价标准,总结了该区块油层和水层的色谱特征,对比发现油层和水层的色谱特征差别十分明显,能准确地识别油气层,可以推广应用。the south China sea in eastern pearl river mouth basin,panyu a block for gas logging value is low,fluorescent display is not obvious,such as complex reservoirs,the conventional logging is difficult to accurately identify oil and gas shows,this paper introduces the analysis of the geochemical pyrolysis gas chromatography technology principle,evaluation standard,summarizes the block oil layer and water layer chromatographic characteristics,compared with oil layer and water layer chromatographic characteristics difference is obvious,can accurately identify oil and gas layer,can be applied.

关 键 词：地化录井 热解气相色谱 原油性质 油气识别
