Production performance analysis of oil well with submersible electric pump

A modified model to simulate the crude properties is presented,and its results correlate well to the PVT curve.The calculation methods for the fluid temperature increment in the submersible electric pump and the temperature gradient along the well bore are also developed.By introducing the techniques for describing and calculating the trajectory of a well bore to the multiphase flow calculation,the problems appeared in calculation for the curved well bore sections were successfully solved.As a result,the distribution of every parameter along the well bore with any shape can be found.On the basis of these,the simulation and analysis on production performance for a well with submersible electric pump were achieved by means of the test data from capillary,producing fluid level and pump characteristic curves.This method has brought a good effect when used in oil fields.
