摘要/Abstract

摘要： 调整井固井过程中地层压力时刻处于波动状态，这导致了严重的水窜；此外，储层改造时水泥环破裂将造成环空窜流。针对调整井固井存在的上述问题，首先，通过优选防窜增韧材料进行复配研究，制备出了一种动态压力下固井防窜增韧剂。然后，针对动态压力下水窜的特点，采用自主研制的新型水窜评价装置对防窜增韧改性水泥浆的防水窜性能进行评价。此外，还评价了防窜增韧改性水泥石的膨胀性能、力学性能和防窜增韧改性水泥浆的工程性能。最后，在渤海油田进行了现场试验。结果表明，防窜增韧剂增强了水泥浆的抗动态水分散性能和水泥石胶结界面的防水窜性能，减少了失水量和体积收缩；同时，该材料显著提升了水泥石的韧性，并且对水泥浆的各项工程性能没有负面影响；现场试验结果显示固井质量优于邻井。说明该防窜增韧剂可满足动态压力下固井防窜和增韧的要求。

Abstract: During the cementing process of adjustment well, the formation pressure is always in a state of fluctuation, which leads to serious water channeling; in addition, when the reservoir is reformed, the fracture of cement sheath will result in annulus channeling. In view of the above problems existing in the cementing of adjustment wells, a kind of anti channeling and toughening agent for cementing under dynamic pressure was prepared by optimizing the anti channeling and toughening materials. Then, according to the characteristics of water channeling under dynamic pressure, a new self-developed water channeling evaluation device is used to evaluate the water channeling performance of the modified cement slurry. In addition, the expansion property, mechanical property and engineering performance of the modified cement paste were evaluated. Finally, the field test was carried out in Bohai Oilfield. The results show that the agent enhances the anti dynamic water dispersion performance of cement slurry and the anti-water channeling performance of cemented interface of cement paste, reduces the water loss and volume shrinkage; at the same time, the agent significantly improves the toughness of cement paste, and has no negative impact on the engineering performance of cement slurry; the field test results show that the cementing quality is better than that of adjacent wells. The results show that the anti channeling and toughening agent can meet the requirements of cementing anti channeling and toughening under dynamic pressure.
