Description
Technical field
The present invention relates to oil exploitation drilling technique field more particularly to a kind of packers for annular space pipeline.
Background technique
After the investment exploitation of oil field, with the growth of mining time, stratum energy decline causes formation pressure constantly to decline,
Underground crude oil is caused largely to deaerate, viscosity increases, and oil well output greatly reduces, or even will appear the case where stop-spraying stops production.At this
In the case of kind, the method to oil-field flooding is generallyd use to supplement bottom energy, is kept or is improved formation pressure, to realize
The smooth exploitation of crude oil.
Currently, oil-field flooding mainly passes through water injection pipe to oil-field flooding, water injection pipe is corroded in order to prevent, is often existed
Outer protection tube is put on outside water injection pipe, water injection pipe and outer protection tube form annular space pipeline.Since oil field is to be located at seabed or underground, outer protection tube
The erosion by seawater or soil, outer protection tube can inevitably rupture for a long time, and outer protection tube is exposed to once rupturing water injection pipe
In extraneous corrosive environment.The existing solution to outer protection tube rupture is that preserving timber is filled between outer protection tube and water injection pipe
Material need to all fill anti-corrosion material to whole annular space pipeline, in turn result in staff's since annular space length of pipeline is longer
