Modelowanie przepływu dyspersji cementowej jako cieczy nieliniowo plastycznie lepkiej
Flow modeling of the cement dispersion as non-linear viscoplastic fluid

Summary/Abstract: The analitycal solution for pipeline and annular fl ow of the cement dispersion for non-linear viscoplastic model of the fl uid, compared with another reological models were presented in the paper. The calculations of the pressure gradient and injection range shows that it is necessary to take into account the friction factor in the theoretical analysis of the cement grout flow.
