The invention provides a novel oil sleeve carbon dioxide anti-corrosion material selection chart and mainly aims at guiding the economical and reasonable anti-corrosion material selection for oil sleeves for oil and gas fields with reservoir stratums containing carbon dioxide. The chart comprises not only carbon steel and 13Cr stainless steel oil sleeve materials; meanwhile, low Cr steel materials of different types newly developed in recent years are demarcated in an appropriate interval; and the satisfied anti-corrosion materials can be selected conveniently and quickly according to the distribution ranges of the temperatures of the oil and gas wells and the carbon dioxide partial pressures. The shortage of only available oil sleeve material selection between the carbon steel and the stainless steel is made up. The chart is obtained on the basis of lots of indoor experimental data and field collected data; the use waste or short service life of the sleeves can be effectively avoided due to over-high or over-low anti-corrosion level design; the safe production of the oil and gas fields can be ensured; and the oil sleeve cost can be reduced.
