Study on Rheologic Properties of Three-Phase Foam Drilling Fluid

Abstract:

The rheologic model of three-phase foam drilling fluid can be optimized with grey correlation analysis method. The Karson model is the main model for description of the rheologic properties of the drilling fluid.The drilling fluid has high apparent viscosity, high shear strength and strong shear dilution performance. The rheologic parameters are mainly influenced by gas liquid ratio and base mud properties.
