To know the anticorrosion ability of 80SS pipeline steel in gas field and enhance its application in Tarimu gas field,the corrosion of 80SS pipeline steel was studied in a simulative environment of Tarimu gas field containing H2S and CO2.

H_2S/CO_2 corrosion behavior of 80SS steel under high temperature and high pressure;

In CO2/H2S containing corrosive agueous solutions,the corrosion behavior of SM80SS tubing steel was studied.

First time introduces P_(CO_2)/P_(H_2S) sub pressure to forecast model of tubing steel corrosion speed in order to find out the relation between tubing steel corrosion speed CR and CO_2 sub pressure P_(CO_2)、H_2S sub pressure P_(H_2S).

In two-phase fluid medium of sulfate acid solution,corrosion wear properties of N80 and P110 oil well tube steels were investigated with a self-assembly wearing device,and synergistic rate and interactive ratio of corrosion wear for two steels were comparatively analyzed respectively, and choice of service condition of two steels was discussed.

Electrochemical corrosion behavior and mechanism of N80 steel in the aqueous solution of carbon dioxide under high-temperature high-pressure;

Effect of CO_2 partial pressure on corrosion scales of tubular steels;
