%X The corrosion failure of a three-stage pump's down part used for 97 days in DH 1-5-7 oil well of Tarim oil field was analyzed simply.The down part was mainly composed of flange,vane and cylinder body.There was no much more corrosion product on the surface of down part,which suffered severe corrosion.The failure was caused both corrosion and runoff of oil,gas and water mixture.Different materials composed of the down part formed the galvanic corrosion cell.The existence of chloride ions in the pits also promoted pitting corrosion.
