摘要: 基于长庆油田 A区块注水管线的腐蚀现状, 实验室内模拟注入水与管线接触腐蚀, 采用挂片失重法, 在不同影响因素的实验条件下, 改变注入水的流速、 温度、 压力等条件进行油田注水管线腐蚀速率研究, 然后利用灰 色关联分析的方法, 以油田注水管线腐蚀速率作为参考序列, 把各个影响因素作为比较序列, 获得各影响因素的关 联系数, 进而得出其关联度, 根据关联度计算所得结果按照大小值依次进行排序, 结合实验结果与理论计算, 确定 A 区块注水管线腐蚀速率的主要影响因素。为油田同类区块注水管线防腐治理提供了参考依据。

Abstract: Based on the corrosion status of water injection pipeline in A block of Changqing oilfield, contact corrosion between injected water and pipeline is simulated in laboratory. The weightloss method is used to study on the corrosion rate of oilfield water injection pipeline under different experimental factors (current speed, temperature and pressure). Taking the corrosion rate of oilfield water injection pipeline as the reference sequence, and the various influence factors as the comparison sequence, the Grey Relation Analysis method is adopted to get the correlation coefficient of various influence factors. Then, the correlation degree can be calculated. According to the size value of the calculation, the correlation degree can be sorted. Combined with the experimental results and the theoretical calculation, the main influence factors of water injection pipeline corrosion rate in A block are determined. This provides a reference for the same kind of oilfield block on water injection pipeline corrosion control.
