Centrifugal pumps are widely used in the oil and mining industries. In contrast to water pumps, centrifugal industries for transportation of drilling fluid, which is typically non-Newtonian fluid. Drilling fluids usually modeled as power-law with varying shear viscosity imposed rates. this paper, a numerical simulation fluid flow pump was simulated, only flow-rate magnitude, using comparison. T...

an improved model of mud dispersion has been introduced in this work. the advantages of this model consist of a new analytical correlation for dispersivity by using resistivity log data and using a new aspect of capacitance dispersion model. mathematical formulations were expressed, solved by numerical model taking advantage of actual log and formation data. achieved results yielded reasonable ...

At present, the formation mechanism of gas hydrate (hereinafter referred to as hydrate) plugging in wellbore during deepwater drilling is not clear, so there are problems such overuse inhibitors and low utilization efficiency inhibitors. Therefore, view risk under different working conditions drilling, research was carried out on area deposition plugging. Taking an atmospheric well South China ...

The most important constituent of drilling operation success is keeping the fluidrheological properties within a certain limit to maintain continuing their functions in goodmanner. To achieve that, mud system needs continuous and direct supervision such asmeasuring its rheological treating any deviation values. Viscosity themost property hydraulic program due relation with bottom holecleaning d...
