“…The complete descriptions of such models are available in many books (Wilkinson 1960;Bird et al 1987;Carreau et al 1997;Khasanov and Bulgakova 2003;Mirzadzhanzade et al 2005;Chhabra and Richardson 2008;Basniev et al 2012) and review papers (Bird et al 1983;Chhabra et al 2001;Mitsoulis 2007). Rheological studies established deviation from Newton's law of viscous friction, namely the violation of the linear relationship between the shear stress s and the shear strain rate c, as a particular case-the existence of the critical shear stress (yield stress) s 0 .…”

Experimental studies have proved the ability of high-viscosity oil to display at flow the properties typical of non-Newtonian systems. The relationship between pressure gradient and rate of movement in real reservoirs may be non-linear due to the interaction of asphaltenes and resins, forming the plastic structure in the oil. The impact of the restructuring processes on the viscosity of the oil and the possibility of Darcy's law violation are not considered in most of the known hydrodynamic simulations. The authors of the article justified the analytical model of the pseudostationary flow of non-linear viscoplastic oil to the vertical well with a random configuration of the drainage area. The article presents the results obtained using the model in real design, including the well test analysis. The result of the study is the choice of the system of reservoir stimulation, which allows effective regulation of the structural and mechanical properties of high-viscosity oil. The considered mathematical model is useful for small high-viscosity oil fields to calculate variants with vertical wells. It can help to justify well spacing, the feasibility of address increase in the pressure drawdown and the use of thermal methods.
