The oilfield need to calculate the packer’s displacement of separated zone water injection string. Analyzed the force of the separated zone water injection string, and established the physical model and mathematical model. Using the traditional boundary processing method of tubular mechanics to calculate the displacement of separated zone water injection string, discovered that the accuracy cannot meet the requirement of the oilfield. Therefore consider the influence of all packer’s frictional force on the water injection string’s stress condition, and propose a new method to deal with the boundary condition, compared the calculation results with magnetic location results, the calculation results can meet the accuracy requirements of oilfield.
