众所周知,注水井结构给注水带来了严重的危害,并大大降低了注水系统的效率,增加了修井的次数。如果注水井管线腐蚀,堵塞油层,就会使注水不断上升,损坏注水的设备,从而缩短了注水井的免修期,直接造成注水井报废的严重情况。因此,研制与开发注水井防结垢工艺技术,已经迫在眉睫。
It is well-known that the injection well structure poses a serious hazard to water injection and greatly reduces the efficiency of the water injection system and increases the number of well interventions. If the injection well pipelines corrode and clog up the oil layer, the water injection will continuously increase, which will damage the equipment for water injection, shortening the maintenance-free period of the injection wells and directly causing the serious situation of the injection wells being scrapped. Therefore, research and development of injection wells anti-scaling technology, has imminent.
