Research on a New Latex Anti-Gas Channeling Cement Slurry System

Yunwu YOU, Conglian ZHANG, Ding MA

Abstract


It is one of the technical problems existing in the current cementing technology that gas channeling frequently occurs after the well cementation process. The new latex anti-gas channeling cement slurry system is put forward to solve this problem effectively and also filled up the domestic blank in this field. The study found that the new cement slurry system has the good ability of water loss control, liquidity and the thickening time can be adjusted. The static gel strength analysis and gas channeling simulation analysis shows that under the condition of high temperature, the anti-gas channeling has good effect. In addition, the sensitive factor experiment research shows that the cement slurry system has less affected by the site factors, so it has good application prospects.
