Abstract

Abstract:

Based on the problem of annulus channeling caused by water invasion of the adjustment during wells cementation, AMPS, AM, AA and SA were used as raw materials to prepare a water-soluble hydrophobically associating polymer AAAS by free radical micelle polymerization to enhance the anti water invasion ability of cementing slurry and improve the channeling resistance of cement slurry in order to improve the cementing quality of such wells. The microstructure was characterized by means of IR, NMR, SEM and GPC. The water invasion resistance and basic engineering performance of AAAS cement slurry system were evaluated. The results showed that AAAS can significantly improve the water invasion resistance of cement paste. Compared with the 0.3MPa water invasion channeling through pressure of blank cement slurry, the water invasion channeling through pressure of 0.9% AAAS cement slurry system was increased to 6.9MPa, which greatly improved the anti channeling ability of cement slurry. The 14d bending strength was 8.2MPa and the compressive strength was 31.5MPa, which can meet the needs of long-term cementing of adjustment wells. Therefore, it was expected that AAAS would have a good application prospect in anti water invasion and channeling prevention of adjustment well cementing engineering.

摘要：

针对调整井固井时水侵导致的环空窜流问题，本文以AMPS、AM、AA和SA为原料，通过自由基胶束聚合法制备一种水溶性疏水缔合聚合物AAAS来增强固井水泥浆的抗水侵能力，改善水泥浆的防窜能力，以提高该类井的固井质量。利用红外、核磁、扫描电镜及凝胶渗透色谱等手段对AAAS进行了微观分析表征，并对AAAS水泥浆体系的抗水侵性能及基本工程性能进行了评价，结果表明AAAS可明显提高水泥浆体的抗水侵能力，较之于空白水泥浆水侵后0.3MPa的窜通压力，加量为0.9%AAAS的水泥浆体系，其水侵后的窜通压力提高达到了6.9MPa，大幅度提高了水泥浆的防窜能力，且14天抗折强度为8.2MPa，抗压强度为31.5MPa，能够满足调整井固井水泥环长期封固的需要。因此，AAAS在调整井固井工程抗水侵和防窜中具有良好的应用前景。
