摘　　要：针对中原低渗油田结盐严重的问题,研制出一种新型抑盐剂配方,当药剂加量为300 mg/L时,抑盐率达93%,用现场污水试验时,相对现场药剂其抑盐率提高30%以上。岩心试验表明该配方对地层无污染。在加注工艺方面提出地层-井筒一体化技术,配合综合监测技术,实施效果良好。In order to solve the problem of serious salt buildup in Zhongyuan low permeabili- ty oilfield,a new salt inhibitor was prepared, when its quantity was 300 mg/L,its anti-salt buildup ratio was 93 %,and it enhanced 30 % more than the local salt inhibitor,while the test was by the local oil well wastewater. Core test indicated that the agentia was not contamina- tive to the stratum.Stratum and well-shaft integration technology was designed in filling pro- cess,its implementation effect was fine cooperated with comprehensive monitoring technology.
