油田防垢技术及其应用进展

Oilfield inhibition technology and application progress

在油田开发过程中,结垢会给生产带来很大影响,防垢方法有投加化学药剂、超声、电磁等,也可以通过改变工艺来降低垢的生成。对油田结垢的机理及影响因素进行了阐述,介绍了目前常用的化学和物理防垢方法以及工艺,并对其优缺点做了总结。

In the oilfield development process, scaling brings great influence on production. The mainly methods for anti- scale include dosing chemicals, using physical methods such as ultrasound, electromagnetic, etc. or changing the process to re- duce the formation of scale. The scaling mechanism and affecting factors in the oilfield are presented, and the current common physical and chemical methods and processes are introduced, and the advantages and disadvantages are summarized.
