摘要:

海上油田因时空承载等受限,水质达标处理难度远大于陆地油田。基于渤海主力注水油田的水质普查结果,明确了海上油田注水水质存在的主要问题,采用药剂换型、水处理设备设施改进等手段进行改善。渤海油田"十三五"期间水质达标率连续3年保持在95%以上,水质改善效果明显。

Abstract:

Due to the limitation of space-time bearing capacity, it is much more difficult to reach the water quality standard in offshore oilfield than in land oilfield. Based on the water quality survey results of the main water injection oilfields in Bohai Sea, the main problems of water injection quality in offshore oilfields were clarified. Through a series of water quality improvement measures, such as reagent replacement, water treatment equipment and facilities improvement, the water quality compliance rate of Bohai Oilfield during the 13th five years plan period was maintained at a high level of more than 95% for three consecutive years, and the water quality improvement effect was obvious.

Key words: offshore oilfield, water injection, water quality improvement
