Analysis of the injection well casing failure causes and prevention control
Abstract: As the injection well casing work environment deteriorating, suffered increasing the load, resulting in varying degrees of damage to the casing. To this end through the tube necking deformation and damage mechanism of casing leakage analysis, to identify prevention and treatment to prevent shale casing deformation method of the upper casing corrosion leakage, high-pressure water injection wells to prevent or reduce damage to the casing, for the low permeability normal oil field water injection to provide a solid foundation.
Keywords: casing; water; corrosion 1 Introduction Commonly used for low-permeability oil fields development of high-pressure water injection method, although the high-pressure water injection to achieve significant economic benefits, but also the injection well casing deteriorating working conditions, increasing the load suffered casing, resulting in varying tube Reducing the extent of the rupture and even some shallow tube wells also appeared in the case of leakage channeling this end an urgent need to identify the cause of these fields the main casing damage, and take the appropriate measures to prevent or reduce high-pressure injection wells The casing is damaged, this low-permeability oil fields on the future development of the normal water has an important significance.
2, high-pressure injection well casing damage characteristics
Low-permeability oil fields damaged by high pressure water injection well casing pipe leakage, necking deformation-based, deformation serious rupture phenomenon. The statistics, 86.2% of the casing damaged well casing damage occurs normally in the transfer within 5 years after injection. Casing leakage occurs mainly in the upper casing section is not cementing wells, necking deformation mainly located near the site of dissection and perforation perforation well section, and the necking deformation is generall
