| Abstract: | In consideration of the problems in stratification water injection process of Jianghan Oilfield,which includes that the injection string and tube and casing are not protected,the packer performance is poor,its working life is short,its effect is poor,which can not meet the needs of high pressure water injection,the life of injection string is short under various functions.The corresponding methods are proposed,high pressure stratification water injection string and matched tools are used,such as a packers for the stratification water injection,water well anchors and string telescoping compensator.Field application shows the technique can be introduced in oilfields. |
