| Abstract: | Foam drilling fluid is a new-type low-density drilling fluid available for the unbalanced drilling. The influences of magnetic field on the properties of foam drilling fluid were studied experimentally. The rheology parameters of foam drilling fluid before and after magnetization were compared. The results indicate that the magnetization can obviously change the properties of the foam drilling fluid and reduce the plastic viscosity and visual viscosity of the magnetized foam drilling fluid. The dynamic shear force and the static shear force varied with the change of magnetic field strength. Although magnetic treatment can influence the shearing stress, the liquid property of the foam drilling fluid can keep stable. |
