In the deep water drilling, eye scurf concentration distribution problems have been an important research content, cutting the concentration distributions of mud displacement by, debris diameter, the influence of the time. Through the establishment of debris over time distribution equation of concentration, according to a practical well, the debris concentration is discussed, debris flow with the diameter of the trend. At the same time, the debris of the late time is also calculated.%在深水钻井中,眼屑的浓度分布问题一直是一个重要的研究内容.岩屑浓度的分布受到泥浆排量、岩屑直径、时间的影响.通过建立岩屑浓度随时间的分布方程,根据一口实际井,讨论了岩屑浓度随排量、岩屑直径的变化趋势.同时,还计算了岩屑的迟到时间.
