EVALUATION OF CORROSION STATUS OF OIL TUBE LN2-3 OF WELL BORE AT LUNNAN OIL FIELD
LN2—3井油管腐蚀行为

A safe, simple, reliable, practical coupon holding instrument which could evaluate the corrosion status of oil tube was used. The surface of the corrosive coupons was observed by SEM and the corrosive products were analysed by X\|Ray diffraction instrument. Combining the simulated test, it is proved that the corrosion of LN2\|3 oil tube belongs to the moderate one.\=
