In recent years, Changqing Oilfield has continuously enlarged the scale of exploration and development, and its oil and gas equivalent output has exceeded 6,500 × 104t/a. However, the oilfield has been developed by multiple reservoir system stacking, and it has gradually entered the stage of medium-high water cut, and scaling has become more and more prominent impact of production system. In accordance with compose the prevention and control strategy, chemical and physical scaling technology research and on-site tests have been combined to extend the scaling cycle and slow down the scaling rate, and achieve good results.
