Research on separation efficiency for oil/gas separator of submersible electrical pump

The criteria equation was established by using dimensional analysis; through the method of field experiment measuring the flow parameters of two-phase-flow in the gas-separator in this paper, combining with the criteria equation and experiment data, the mathematical model, which can quantitatively describe the relation between separation efficiency and the gas fluid ratio by using numerical method, is established; and the relational plate is plotted between the separation efficiency and the separation time in the case of different gas fluid ratio, which can provide theoretical foundation for the optimization of the well production parameters and the geometric structure parameters of the oil/gas separator under the submersible electrical pump.
