摘要：

针对稠油的黏度高，族组成中非烃和沥青含量高，饱和烃和芳香烃含量低，全烃色谱图很难反映各油层与井口原油的差异性，应用气相色谱指纹判识稠油井的主要产油层位困难等问题，利用辽河油田某多层混采稠油井各产油层的储层岩石（储层沥青）和混采原油作样品，进行饱和烃和芳香烃色谱-质谱实验，通过星形图分析、聚类分析、因子分析等技术的分析和研究，有效地判识了该多层混采稠油井的主要产油层位，并提出了有针对性的生产调整建议，从实施情况来看，效果明显。该方法具有适用性强、投资少、周期短、准确、快速等特点,有推广应用的前景。

Abstract:

For the high viscosity of the heavy oil，the high content of the non-hydrocarbon and asphaltic bitumen and the low saturated hydrocarbon and aromatic hydrocarbon，it is difficulty to identify the difference of each pay zone and the
well head heavy crude oil with chromatogram.By using reservoir bitumen of each layer and the well head heavy crude oil from certain multilayer heavy crude oil wells（Liaohe Oilfield）as experiment analysis samples，the samples are researched and analyzed by means of the fingerprint feature of gas chromatogram-mass spectra（GC-MS） of saturation hydrocarbon and the aromatic hydrocarbon.According to the technologies such as fingerprint correlation star picture，clustering analysis and factor analysis，the key pay zones of multilayer heavy oil wells are identified.Effect is obvious from actual enforcement result.This technology is applicable，costs less with short period，high accuracy and quickly putting into use，and there is the prospect of popularizing application.
