摘要: 用電化學方法研究了水化學因素對套管鋼在模擬油田水中腐蝕的影響,包括亞硫酸鈉除氧效果、溶解氧濃度、氯離子濃度、介質溫度對腐蝕的影響,得出了將腐蝕速率控制在石油部行業標準SY5329-88中規定的腐蝕速率的臨界溶氧濃度、氯離子濃度和溫度值。Abstract: The influence of water chemistry factors on corrosion of oil pipeline steel in simulated water has been studied by electrochemical method,including discharging of oxygen by Na2SO3,dissolved oxygen,concentration of Cl- and temperature.The critical values of dissolved oxygen, Cl- concentration and temperature below which corrosion rate will not exceed the confined value of Standard SY5329-88 have been obtained.
