摘要
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 form 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.关键词
