摘要: 针对高泥质、粉细砂岩油藏地层微粒运移堵塞、冲蚀破坏挡砂屏障导致油井液量大幅下降的问题，通过实验数据和相关计算，分析了不同纳米材料的吸附效率，优选出溶胶- 凝胶型MgO 纳米材料涂覆支撑剂作为砾石充填层，其微粒吸附效率达78.85%，流出物的浊度仅为阳离子抑砂剂的5.5%，流出物中含砂量约为用阳离子抑砂剂的9.3%，固砂效果远优于油田常规阳离子抑砂剂。在胜利油田 LNJ501 井现场应用后油井采出液含砂量0.01%，液量是施工前的3.42 倍，有效生产时间389 d，说明溶胶- 凝胶型MgO 纳米材料抑砂技术可达到恢复产量、延长防砂有效期的目的。

Abstract: Migration of fine grains in reservoir formations with high clay and siltstone contents may plug, erode, and damage sand barriers, and cause significant reduction of fluid productivity. Absorption efficiency of various nanometer materials have been reviewed by using relevant test data and calculation results to pick out the sol-gel MgO nanometer material as coated proppant in gravel-packing layers. With absorption efficiency of 78.85% for fine grains, turbidity of its outflow fluid is only 5.5% of that obtained by using cationic sand control agent, and sand content in its out-flow fluid is only approximately 9.3% of that contained in fluid out of cationic sand control agents, which suggests its sand consolidating performance is far better than conventional cationic sand control agents currently used in oilfields. After it was applied in Well LNJ501 of the Shengli Oilfield, sand content of the produced fluid was less than 0.01%, and the fluid productivity of the well was 3.42 times of that before the treatment, and effective production time of the well was 389 d, which indicates the sol-gel MgO nanometer material can effectively enhance fluid productivity and extend effective sand control period.
