YG系列油管防腐蚀涂料的性能研究

Study on Performances of YG Series of Anti-Corrosive Coatings for Oil Tube

针对井下油管的腐蚀环境和防腐蚀涂覆的需要,研制了YG系列油管防腐蚀涂料,包括YG-01烘烤固化型油管涂料和YG-03常温固化型油管涂料等。性能研究结果表明:YG系列油管防腐蚀涂料具有优异的耐盐雾、耐酸和耐油田污水等耐腐蚀性能;以及在高温高压下耐H2S/CO2腐蚀和耐碱等性能,并具有较好的综合性能,可以满足不同腐蚀环境下井下油管内防腐的涂覆需要。其中YG-01满足国内现有进口油管/钻杆内防腐涂覆作业线的工艺要求。

Aiming at the corrosion circumstances of downhole oil tubes and the needs of anti - corrosive coatings, YG series of anti - corrosive coatings for oil tubes are developed, in terms of YG - 01 baking anti - corrosive coatings for oil tubes, YG - 03 air - drying anti - corrosive coatings for oil tubes and et al. The results of the performance study show that YG series of anti -corrosive coatings for oil tubes have excellent corrosion resistances in terms of salt -fog resistance, acid resistance, oil -field waste water resistance and et al, good H2S/ CO2 corrosion resistance and alkali corrosion resistance under certain high temperature and high pressure, and also very good comprehensive performances. YG series of anti- corrosive coatings for oil tubes can meet the internal protective requirements of downhole oil tubes in different corrosion circumstances. YG- 01 coatings can meet the technical process requirements of present imported internal anti - corrosion coating lines for oil tubes/ drill pipes.
