摘　　要：本文在充分调研的基础上,综合各种振动固井装置的优点,提出了新型井下双向振动脉冲固井装置的设计方案。该方案采用多节组合模式,在整个注水泥施工过程中,可同时产生纵向振动、径向振动以及环空脉冲;在受到复合波作用的影响下,水泥浆的性能得到有效的改善,初凝固时间缩短,其胶结质量得到明显提高。In this papar,based on the full investigation of the advantages of existing vibrators of cementing,a new Bi-directional vibrator of cementing pulsation working in downhole is presented.The vibrator of cementing combined multi-section mode,it can produce vertical vibration,radial vibration and annulus radial pulse among cement slurry.Under the influence of complex waves,The results indicate that the performance of the cement slurry can be greatly improved with the pulsation treatment,the time of initial set is reduced,and the bonding quality is improved.
