随着胜利油田水驱油藏进入特高含水开发阶段，含水升高、注采强度增大等对化学防砂效果和有效期提出 了更高的要求。总结了胜利油田特高含水期化学防砂技术面临的开发矛盾，介绍了胜利油田在防砂控水一体化 技术、高渗滤砂管提液技术、低温固砂技术和分层注入技术方面的进展，为特高含水期油田化学防砂提供借 鉴。参20

As the water flooding reservoir at Shengli oilfield enters ultra-high water-cut extraction period，the water-cut and the intensity of injection and extraction increase quickly which proposes higher requirement to the production and validity period of chemical sand control. It summarized the extraction confliction of Shengli oilfield at ultra-high water-cut extraction period， introduced the improvement about the technology combination of sand controlling and water-cut reducing，chemical screen with high permeability，sand consolidation technique at low temperature and multi-layer injecting technology. It provided experience of the chemical sand control for water flooding reservoir at ultra-high water-cut oilfield.
