摘要
In this paper, a set of charts is developed to allow drilling engineers to quickly estimate the cuttings volumetric concentration in the wellbore. The most-important parameters for hole cleaning are divided into several ranges on the basis of their sensitivity to cuttings concentration in the wellbore. A series of charts is obtained by running a hole-cleaning simulator, which is based on a large number of experimental and modeling studies of cuttings transport. The difference between the charts' prediction results and experimental data is within 20%. Drilling engineers can quickly estimate the cuttings volumetric concentration by looking up the charts and conducting very-simple calculations.
