摘要
随着开发低渗透油藏注水时间的延长,注水井油层结垢、污染堵塞日益严重。针对传统酸化工艺酸化半径小,酸化效果差的缺点,研究实施了低渗透油藏缓速酸化工艺新体系。自2003年10月开始在濮城油田实施,截止目前已成功实施89井次,在降压、增注、改善剖面、节电等方面取得良好效果,是濮城油田改善低渗油藏开发的上产主要措施。
The note well oil reservori forms dirt and pollution seriously along with low to permeate oil reservoir for water flooding to develop, with develop water flooding extension. Focus on the traditional acid system has little radius and bad acid result, the system of low to permeate oil reservoir slow speed sour craft has been studied and implemented. It has been implemented 89^th succeeded in the oil field of Pucheng, make the good result in stepping down, increasing the note, improving the section, economizing on electricity,since October,2003. And it is the main measure that make low to permeate oil reservoir increase output in Pucheng Oil Filed.
