Multi-end-member determination method, device and equipment for mixed-source oil

Abstract

The embodiment of the invention relates to the field of petroleum geology and the field of geochemistry, in particular to a multi-end-member determination method, device and equipment for mixed-source oil, and the method comprises the steps: obtaining a plurality of target geochemical parameters meeting a preset stable condition; determining a plurality of target end member oils for forming the mixed source oil; determining a plurality of corresponding parameter value sets according to the plurality of mixed source proportion sets; each mixed source proportion set comprises mixed source proportions of a plurality of target end member oils, and each parameter value set corresponds to one mixed source oil of the plurality of target end member oils under one mixed source proportion set and comprises values of a plurality of target geochemical parameters of the mixed source oil; constructing a mixed source oil plate according to the corresponding relation between the mixed source proportion set and the parameter value set; and inputting the values of the multiple target geochemical parameters of the target mixed-source oil into the mixed-source oil chart to obtain the mixed-source proportions of the multiple target end member oil in the target mixed-source oil.
