摘　　要：粉细砂岩油藏由于地层砂粒度中值细,层内非均质性严重,泥质含量高,防砂难度大。针对此类油藏,研制了新型超分子固砂剂DXGY—1,实验表明具有在地层内自组装、固砂性能强和渗透率保持率高的特点,现场应用效果良好。Sand prevention is very difficult in fine sandstone reservoirs because of fine median formation sand grain size, seriously heterogeneity, and high shale content. For this kind of reservoir, a new type of supramolecular sand fixing agent DXGY--1 is developed. Experimental results show that DXGY--1 has characteristics of self - as- sembled in formation, strong sand consolidation performance, and high permeability conservation rate. The field application effect is good
