摘　　要：新疆玛湖凹陷区夏子街组、下乌尔禾组地层流体性质复杂,难以识别,传统气测录井解释图板符合率低。利用研究区试油井的气测录井数据,通过气测录井敏感参数挖掘,提取表征含油性的气测录井参数,并将多参数融合构建气测含油性指数。填充系数和气测含油性指数对储层流体的识别作用明显,分别以此两项参数为横、纵坐标建立了符合该区的气测录井解释新图板,并建立了解释标准。经试油井验证,新图板解释评价效果较好,具有一定的推广应用价值。The formation fluid properties of Xiazijie Formation and lower Urho Formation in Mahu Sag of Xinjiang are complicated and difficult to identify,and the coincidence rate of traditional gas logging interpretation chart is low.Based on the gas logging data of the test well in the research area,the gas logging parameters characterizing oil-bearing properties are extracted by gas logging sensitive parameters excavation,and the multi-parameter fusion is used to construct the gas logging oil bearing index.Filling coefficient and gas logging oil bearing index have obvious effects on the identification of reservoir fluid.Taking these two parameters as abscissa and ordinate respectively,a new gas logging interpretation chart in line with this area is established,and the interpretation standards are set up.The well test verifies that the interpretation and evaluation effect of the new chart is good,and it has a certain popularization and application value.
