| Abstract: | This paper described the discriminate method for the flow pattern of foams in annulus, and then summarized the mathematical models to calculate the slip velocity and the transport ratio of cuttings in different flow patterns. According to the case history of drilling, the inference of various major relevant drilling parameters on the cuttings carrying capacity of foams was calculated and analyzed, and the suitable ranges of various drilling parameters to ensure the enough transport ratio of cuttings were provided, which would be beneficial to the field applications. |
