摘　　要：在固井及油气开采过程中,环空窜流是一种常见的质量问题,对油气生产和油井寿命构成非常严重的威胁。要想实现高质量的层间封隔,保证油井正常生产和油井寿命,就必须尽量避免产生环空窜流。本文详细的介绍了固井后环空窜流的类型、机理及其危害性,并阐述了近几年来国内外防窜工艺技术以及防窜水泥浆体系。During cementing and oil production,fluid channeling is the common quality issue,which can pose a threat to oil production and well s life.In order to have a positive cementing to keep oil wells in normal production,fluid channeling should be avoid.This paper analyzes the reasons,mechanism and damages of fluid channeling in annulus after cementing,and it summarizes recent domestic & oversea anti-channeling technology measures and anti-channeling cement slurrysystem.
