Prediction of conditions of the safe operation of submersible motor

Authors: A.S. Ermakova, E.V. Poshvin (Novomet -Perm CJSC, RF, Perm), S.N. Peshcherenko (Perm National Research Polytechnic University, RF, Perm)

Key words: submersible electrical motor, simulation of termal regime, model reservoir – well – ESPsystem, minimum fluid velocity, ESP system failures.

The technique of selecting safe conditions of submersible motors operation, based on a simulation model of its thermal regime by the methods of computational fluid dynamics is suggested. The correspondence of calculated data to the results of the thermal bench test is shown. By means of commonly used today programs of selection electrical centrifugal pump units for wells borehole fluid properties, required for the transfer the technique on the operating conditions, are determined. Examples of the calculation of the critical speeds of the cooling fluid for a number of submersible motors are given.
