Electric submersible pump

Electric submersible pump (ESP) is a kind of rod-less oil recovery equipment which can lift oil with large displacement. The electric submersible pump and electric submersible pump are lowered into the oil well below the liquid level to pump oil. In addition, the characteristic curve of the electric submersible pump is an important basis for analyzing the working performance of the electric submersible pump well, but the characteristic curve is generally made with clear water as the medium, when swabbing the well fluid (oil, gas, water three-phase medium), The relationship between the displacement and the head will change. The actual pressure head of the electric submersible pump changes with the change of the flow pressure, so the discharge capacity and the supply capacity of the electric submersible pump well in normal production should be coordinated with each other.
