摘　　要：通常通过对油气包裹体的荧光显微镜观察和显微光谱检测来分析储层颗粒中吸附烃的性质。但由于受岩性、油气充注速率和沉积环境条件等因素的影响,沉积岩中油气包裹体的形成有很大的不确定性,给研究带来一定的难度。应用颗粒荧光定量技术对塔河油田储层进行分析研究,挑选了S110井的8个样品进行了定量荧光QGF-E和QGF分析。分析表明石炭系巴楚组,下志留统柯坪塔格组之间有一个残余油层和水层界面。奥陶系鹰山组、一间房组和良里塔格组显示均为油层,分析结果与录井资料基本吻合。该研究结果对塔河地区储层油气藏成藏机理的研究具有重要意义。In order to analyze the property of hydrocarbon adsorption in reservoir,oil fluid inclusions are often investigated by fluorescent microscope and micro spectrum.However,there are some problems in the testing for the uncertainty of fluid inclusions in reservoir due to the characteristics of lithology,oil-and-gas injection rate and sedimentary condition.Not only the samples from Well S87 and S102 but also the 8 samples from Well S110 are analyzed by the QGF-E and QGF before the quantitative grain fluorescence analysis of the reservoirs in Tahe Oil Field.The result shows that there is an interface between oil and water layers in the Carboniferous Bachu Formation and the Lower Silurian Kepintage Formation.The Ordovician Yinshan Formation,the Yijianfang Formation and the Lianglitage Formation are all oil layer,and the result agrees well with the logging data.This is important for the modeling of oil-and-gas formation in the Tahe area.
