摘要: 对目前国内外混源油中不同油源贡献比例定量确定方法的研究状况进行了分析,提出了利用灰色关联分析法拟合模拟混合原油的正构烷烃分布曲线和实验混合原油的正构烷烃分布曲线来确定二元混源油混合比例的方法,即取两者关联度最大时对应的混合原油比例作为混源油的贡献比例,并利用二连盆地达尔其油田的实际混源油检验了该方法的正确性。该方法具有可以任意调节端元油的混合比例及易于推广等特点。

Abstract: The methods for calculating the relative source contribution proportion of the mixed oils at home and abroad were analyzed.A new method for determining the relative source proportion of mixed oils was proposed by using the grey correlation analysis on the n-alkanes distribution curves of the simulative mixed oils and the experimental mixed oils.When the degree of relevance between the simulative mixed oils and the experimental mixed oils is maximum,the proportion is considered to be the relative source contribution proportion of the mixed oils.The method was tested with the natural mixed oils in Daerqi Oilfield of Erlian Basin.The application result indicates that the useful results can be obtained using this method.The proportion of the simulative mixed oils can be altered optionally by using the new method,which is simple and favorable to be popularized.

Key words: mixed oils, grey correlation analysis, simulation experiment, n-alkanes distribution curve, relative source contribution proportion of mixed oils
