The simulator allows computing temperature changes in drilling tubes, annular space and surrounding rocks during washing and cementing. It accounts for changes with depth in geometry of drilling tubes and borehole, mud properties and volumetric rate, thermophysical properties and geothermal coefficient of rocks surrounding borehole, presence of formation with changed thermophysical parameters of the rock. The simulator allows quick and precise determination of the temperature distribution in the system, depending on a number of system parameters at any time; it is necessary for borehole monitoring. It can prevent a number of dangerous complications and takes into account temperature influence on mud and cement properties during the borehole washing and cementing. |
