| Abstract: | Based on the theory of solid-liquid flow,a three-layer transient cuttings transport model for all sections of extended well was developed,and the mechanisms of suspension,rolling and sliding of cuttings,the relative velocity between solid and liquid in suspension layer and the effect of drill pipe rotation were all taken into account.The model was used for calculating and stimulating all sections and processes on actual drilling and circulating conditions.The model was solved numerically by SETS method on t... |
| Keywords: | extended reach well cuttings transport transient model actual drilling simulation |
