ＰＦ６１２型高效除垢剂是黑龙江石油化工厂针对喇嘛甸油田注水井管柱结垢严重的现状，自行研制的一种能快速解除注水系统堵塞的新产品，主要由溶垢剂、渗透剂、缓蚀剂、杀菌剂等配制而成。当ＰＦ６１２型高效除垢剂注入井筒后，其中的溶蚀剂在渗透剂、分散剂等的作用下，迅速与注水井管柱内堵塞物中的碳酸盐、铁离子、硅类、沥青质、胶质等发生反应，将注水井管柱内的堵塞物溶蚀，同时利用ｐＨ值的变化杀死各种细菌。充分反应后再利用井底地层压力，将溶蚀物返排到地面达到除垢目的。采用ＰＦ６１２型高效除垢剂进行井内除垢，可以直接将其注入到井内而不需要动管柱，因而能够在短时间内解堵进而恢复正常生产。
PF612-type high-efficiency descaling agent is aimed at Lamadian injection wells well scale scaling situation in Heilongjiang Petrochemical Company, developed a rapid removal of water injection system plugging new products, mainly by the dissolution agent, penetrant, slow Etchants, fungicides and other preparation. When the PF612 high-efficiency descaling agent is injected into the wellbore, the etchant of the PF612 is quickly mixed with carbonates, iron ions, silicon, asphaltenes, Colloidal reaction occurs, the water injection wells within the column plug erosion, while using the changes in pH to kill a variety of bacteria. Fully respond to the use of downhole formation pressure, dissolved dissolved back to the ground to achieve descaling purposes. PF612-type high-performance cleaning agent descaling well, you can directly inject it into the well without the need for moving strings, which can be in a short period of time to plug the resumption of normal production.
