| Abstract:This paper presents several common rheological models of drilling fluids and analyzes features and the consistency curves of these models.
Through many experiments in laboratory, we obtain rheological parameters of SM vegetable gum drilling fluid. And the consistency curve of SM vegetable
gum drilling fluid is drawn up based on these parameters. It is concluded that its rheology equation is power law model through comparing with common
rheological models. Based on two different characteristic experiments, this study shows that SM vegetable gum drilling fluid is a viscoelastic fluid rather
than pseudo鄄plastic fluid suggested in the past. Comparison with traditional slush indicates that the rheological properties of this fluid are better than mud.
Finally this paper discusses reheological parameters of the SM vegetable gum drilling fluid. |
