摘要

摘要: 固井水窜问题是各油田普遍存在的技术难题，目前缺乏有效的解决办法。针对以上问题，从水泥浆体系出发，首先进行了防水窜材料的结构设计，然后根据结构设计，筛选出相应的防水窜原材料，并通过对其合理的复配研究，制备出了一种新型固井用防水窜材料。实验根据固井不同阶段的水窜机理，采用相应的方式对该材料的防水窜效果进行了评价，结果显示开发的防水窜材料可增加水泥浆内部结构，缩短静胶凝过渡时间，避免水泥石收缩，从而避免水泥浆在不同阶段发生水窜。另外，综合评价结果表明，新型固井防水窜材料可缩短稠化时间、增加水泥石强度，改善水泥浆稳定性，且对水泥浆稠化、流变、失水等性能无不良影响，综合性能良好。

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.
