Pastdoctoral Mobile Station of China University of Petroleum (Beijing), Beijing 102249) Abstract This paper discusses the instruments and procedures available presently for evaluating fltration property, sizes ofpore throats thickness and compressibility of mud cake. Analyzed in this paper are the status quo of using SEM and energy spectrum in studying the microstructure of mud cake and the distribution of mud cake constituents. Studies presently conducted were focused on the observation of surface topography, while knowledge about the interior microstructure of mud cake is stll in demand when optimizing the quality of mud cake. The spatial distribution of the microstructure of mud cake needs to be extensively studied in the future to further understand the mechanism of filtration control and the way of reducing filtration rate, These studies are of help to the development and perfection of the basic theory of controlling drilling fluid filtration and ability of building mud cake, and will provide guide and technical support to the development of new high performancemud additives and to the improvement of drillingfluid technology

随着油气钻探向深部地层的有序推进,高温深井、异常高压井钻井过程中的钻井液流变性及滤失造壁性难以协调统一的矛盾逐渐凸显。在高温深井中,由于地层压力偏高,为防止并涌等复杂情况的发生,常需采用高密度钻井液控制井下压力。然而,由于高密度钻井液的固相含量高等间题,高温作用下的钻井液滤失造壁性能调控技术已成为制约深部
地层勘探开发的技术瓶颈,进一步明确高温高密度水基钻井液滤失造壁性能调控机理是解决当下技术
瓶颈的重要途径(14)。 1泥饼结构模型
