Determination of the temperature operation mode of wells equipped with ESPs and assessment of the probability of complications when the pump unit leaves the optimal temperature zone

This article describes the methodology that allows to calculate the temperature at the pump intake depending on the technological mode of producing wells and demonstrates its application by the example of the stock of producing wells of Samaraneftegaz AO. The temperature increase is calculated taking into account the presence of free gas in the pumping equipment chamber. Such increase negatively affects the operation of the unit as a whole, since there are risks of overheating the cable line in the lower sections of the pump and scale formation in the pump itself.
