摘　　要：濮城油田在长期注水开发过程中,生产油井普遍存在结垢现象。油井结垢往往会导致油井产液量下降,产油量减少。针对油井结垢特点,开展油井硫酸钙除垢剂配方研究,通过室内及现场实施,生产油井均见到了较好的除垢效果,对油田生产起到了积极促进的作用。Pucheng oil field is in the process of water injection development for a long time. The sca- ling in oil wells is widespread phenomenon. The oil well scaling tends to cause a decline in oil well produced fluid volume, and oil production decreases. According to the characteristics of the oil well scaling, the oil well calcium sulfate scale remover formula, was studied. By indoor and field implemen- ration, good descaling effects were obtained. It plays a positive promoting role in oil field production
