随着开发时间的延长，辽河油田Shu-1区地面系统结垢问题愈发严重。因此，研究适应Shu-1区稠油污水的高效除硅工艺可以有效缓解地面系统结垢问题。文章将蒸汽辅助重力泄油（Steam Assisted Gravity Drainage,SAGD）高温分离水作为除硅对象，考察三种除硅工艺的处理效果，包括镁剂除硅、铝剂除硅和机械蒸汽压缩除硅（Mechanical Vapor Compression,MVC），三种工艺的最佳除硅量分别为1 267.2,1 212.7,1 331 mg/L。综合考虑三种除硅工艺的优缺点，以及对Shu-1区地面系统结垢问题的改善情况，推荐MVC除硅工艺，对解决辽河油田Shu-1区地面系统结垢问题具有指导意义。

With prolonged development, scaling issues in the surface facilities of the Shu-1 Block in Liaohe Oilfield have become increasingly severe. Therefore, developing an efficient silicon removal process suitable for the heavy oil produced water in this area can effectively mitigate scaling in the surface system. This study focuses on the high-temperature separated water from the Steam Assisted Gravity Drainage(SAGD) process as the target for silicon removal. Three desilication methods—magnesium-based agent removal, aluminum-based agent removal, and Mechanical Vapor Compression(MVC)—were evaluated for their treatment efficiency. The optimal silicon removal capacities for these three processes were determined to be 1 267. 2 mg/L, 1 212. 7 mg/L, and 1 331 mg/L, respectively. After comprehensively considering the advantages and disadvantages of each method and their potential to alleviate scaling in the Shu-1 surface facilities, the MVC desilication process is recommended. This study provides valuable guidance for addressing scaling challenges in the surface system of the Shu-1 Block, Liaohe Oilfield.
