Abstract Water channeling in well cementing has been a difficult technical problem remained unsolved in petroleum industry till now In a study on anti-water channeling cement slurry, structural design of anti-water channeling additives were done, and based on the design, several anti-water channeling raw materials were selected and mixed in a certain ratio to fom a new compounded anti-water channeling additive. According to the water-channeling mechanisms in different stages of well cementing, the effect of the anti-water channeling additive was evaluated with different evaluation methods. The evaluation results showed that the anti-water channeling additive developed is able to strengthen the interior structure of cement slurry, shorten the transit time of static gel, avoid contracting of set cement, thereby avoiding water-channeling of cement slurry at different cementing stages. The evaluation also demonstrated that the new anti-water channeling additive is able to shorten thickening time of cement slurry, increase compressive strength of set cement, and improve the stability of cement slurry; it has no bad effect on the thickening time, rheology and filter loss of cement slurry. exhibiting good overall properties.

中国大部分陆上油田均已进入高含水开发后期，即使新开发的油藏大多也采用早期注水开发方式保持地层产能这就使固并作业面临水率的问题。目前油气井尤其是调整井固井的水宰问题是各油田
尚未很好解决的技术难题，严重地制约了油田开发战略的实施和油气采收率的提高[1-2]。固井防窜材料的研究多集中在防气窜材料的研究[3-4]，缺乏专门的防水宰材料，而水宰与气宰是不同的，水宰入
