On the importance of а pressure at an electric submercible pump suction

Authors: A.A. Gareev (Oil and Gas Production Department Nizhnesortymskneft, Surgutneftegas OJSC, RF, Nizhnesortymsk), R.F. Sharafutdinov, R.A. Valiullin (Bashkir State University, RF, Ufa)

Key words: electric submercible pump (ESP), operation conditions, pressure at an electric submercible pump suction.

The suction pressure variation ranges, when the electric centrifugal pump of a poor efficiency can be operated, and the concept of limiting pressure at the pump suction, depending on the properties of the oil, are determined. It is shown, that the obtained theoretical results of determination of the pressure at the electric centrifugal pumping unit suction have practical importance at the operation to analyze the status of the unit, at the selection of the unit - to predict its status.
