MECHANICAL ANALYSIS OF ELECTRIC SUBMERSIBLE PUMP IN HORIZONTAL WELLS

Xu Xingping, Li Binghui  
Problems resulting from the use of electric submersible pump (ESP) in horizontal wells are described. A mechanical model of ESP in horizontal wells is given. Differential equations are derived. According to the superimposition principle, deflection formulas for calculating of ESP and the casing string are obtained. Stresses on ESP in horizontal wells are analyzed and a calculating formula is given. A simple example is presented. The result of the example is compared with that given in the reference. They are in good accordance.
