中文摘要:针对目前国内外缺乏一种科学的方法指导固井降失水剂放大合成这一问题,根据降失水剂合成特点,在相似性放大原则上研选了合成工艺条件为主的放大基准,并以此建立了搅拌功率Np放大模型,开发了一种适用于水溶液聚合固井降失水剂的放大合成方法。室内通过放大合成方法,以一种AMPS类降失水剂指导进行了2~10倍体积量放大实验,所得产物较小试最佳产物转化率和120℃API失水量差距分别在5%和10 mL以内,分子量和红外测试结果也表明是同一产物;同时成功指导了50 L中试生产,其产物质量稳定,物理及固井水泥浆应用测试结果与小试一致。结果表明,放大合成方法能有效降低放大效应对放大合成的影响,该研究成果对于固井降失水剂从实验室走向现场应用有着重要意义。

Amplification Synthesis Method Suitable for Aqueous Solution Polymerization Cementing Fluid Loss Agent
Abstract:In view of the lack of a scientific guidance for the Cementing fluid loss additive amplification synthesis method at home and abroad, according to the characteristics of the synthesis of the fluid loss additive, the amplification principle based on the synthesis process conditions was selected on the principle of similarity amplification, and A stirring power Np amplification model was developed to develop an amplifying synthesis method suitable for aqueous solution water loss reducing agent. The indoor amplification method was carried out, and an amplification experiment of 2~10 times volume was carried out with the guidance of an AMPS type fluid loss additive. The difference between the best product conversion rate and the 120°C API water loss was 5% and 10mL respectively. Within the molecular weight and infrared test results also showed the same product; at the same time successfully guided 50L pilot production, the product quality is stable, the physical and cementing slurry application test results are consistent with the small test. The results show that the amplification synthesis method can effectively reduce the influence of amplification effect on the amplification synthesis. The research results have important significance for the cementing fluid loss additive from the laboratory to the field application.
