Technique for calculating technological parameters of non-Newtonian liquids injection into oil well during workover

Technique for automated calculation of technological parameters non-Newtonian liquids injection into a well during workover is presented. At the first stage algorithm processes initial flow or viscosity curve in order to determine rheological and coefficients included equations models fluids. second stage, based on data from previous program calculates design pump operation modes, permissible values liquid rate viscosity, prevent possible hydraulic fracturing. Based results calculations dependencies, decision made necessity changing and/or its composition (components content, chemical base) violation operation, such as unintentional formation fractures due Fracturing can lead catastrophic absorptions and, consequently, increased consumption pumped workover. Furthermore, there an risk uncontrolled gas breakthrough through highly conductive channels.
