摘　　要：为了摸清春光油田井筒和集输管线频繁腐蚀穿孔的原因,在油井现场及联合站分离器出口取水样,对产出液的水质进行分析。通过一系列腐蚀评价试验,初步研究了井筒和集输管线的腐蚀影响因素,研究结果表明,主要的腐蚀影响因素为CO_(2)和硫酸盐还原菌,该研究为油田的安全生产提供了技术保证。In order to identify the causes of frequent corrosion and perforation in the wellbore and gathering pipeline of Chunguang Oilfield,water samples were taken at the oil well site and the outlet of the separator at the joint station to analyze the water quality of the produced liquid.Through a series of corrosion evaluation tests,the factors affecting the corrosion of wellbore and gathering pipeline were studied.The results showed that the main influencing factors of corrosion were CO_(2)and sulfate reducing bacteria,which provides technical guarantee for the safe production of oilfield.
