This paper describes the simulation model of in-situ cuttings concentration change due to lost circulation in horizontal and inclined drilling. The mixture flow of cuttings and mud fluid is regarded as the solid-liquid two-phase flow in the annulus and the numerical simulation model is developed based on the equation of motion of cuttings. The numerical simulation of in-situ cuttings concentration change due to lost circulation was carried out, and the simulated results were compared with the previous research related to the cuttings velocity change due to lost circulation. As simulated results agreed with the experimental results in the previous research, it was confirmed that the model developed here is reasonable. Therefore, by using this model, numerical simulation was carried out again under several conditions. From the simulated results, it was found that the effect of lost circulation on the change of in-situ cuttings concentration and height of moving bed becomes significant according to the decrease of the inclination angle of the drilling well.
