Abstract

Abstract: At present, due to two or more packer being usually used in separate zone water injection technique, as a result, calculation of string deformation becomes complicated. Hydraulic compression packer separate zone water injection technique string is taken as an example, loads and deformations of pipe string during three phases are studied in detail, including anchoring, setting, and water injection. In addition, the instance of pipe string stress is suited, as a result of interlamination pressure difference in water injection, equations derived to calculate stress and deformation during respective phases. The work provides theory for interlamination infusion techniques solving contradiction and adjusting the homogenization of water distribution on reservoir plane.

Key words: separate zone water injection, packer, string, deformation, calculation analysis
