稠油储量占渤海总石油储量的60%，是中国石油接替储量的重要组成部分。多元热流体的应用克服了海上平台承载能力有限的难题，是海上稠油热采的新方向。首次考虑井口注入条件变化及海水流动的影响，以一段时间内注入到管线中的多元热流体为控制体，分别考虑平台、海水段和地层注汽管柱结构的影响，建立了多组分热流体沿程热物性评价模型。计算结果与中国某油田实际热采井沿程热物性参数吻合较好。基于模块计算，评价了多元热流体组成，海水深度对其沿程热利用率的影响，为多元热流体在海上稠油油藏热采中的应用提供了一定的理论支持。

Heavy oil covers about 60%of the total reserve in Bohai Bay,which is a significant part in the succeeding petroleum industry in China. The application of multi-component heat fluid(MCHF)overcomes the problem of limited load of offshore platforms,serving as a new break through in offshore oil production. Considering the impact of various injection conditions and sea water flow for the first time,the model takes the amount of fluid injected within a certain period of time as control volume and concludes the influence of pipeline structures of platform,sea water section and sub-surface section. With Visual Basic program language,the results of the model show a good agreement with the field test data. Based on the model,the impact of the composition of multi-component heat fluid and the depth of sea water on the efficiency along the injection line are studied. Curves and conclusions of this essay would provide some support for the application of this new technology.
