摘　　要：为了解决大庆油田特高含水期厚油层定位压裂固砂胶结强度较低和易出砂的问题,合成了一种改性酚醛树脂,将其与六次甲基四胺固化剂均匀混合反应,得到一种新型固砂剂。通过测试固结体抗压强度,对固砂剂固砂性能进行了单因素影响分析及配方优选。结果表明,在改性酚醛树脂的红外谱图中含有—CH3、—CH2—、苯、苯的1,2,3-三取代—CH—键、Ar—O—R的特征吸收峰和C—N键、—N—H—键、叔醇C—O键的伸缩振动吸收峰,产物的理论结构与实际相符。新型固砂剂中压裂石英砂、线性酚醛环氧树脂、六次甲基四胺固化剂、γ-氨丙基三乙氧基硅烷偶联剂的质量比为100∶6∶0.6∶0.1,固化时间为48 h,此条件下固结体的抗压强度达8.8 MPa,固砂性能良好。In order to solve the problems that sand consolidation strength was low and sanding was easy during positional fracturing inside the thick oil reservoir in ultra-high water cut stage of Daqing oilfield,a modified phenolic resin was synthesized. After the modified phenolic resin and hexamethylenetetramine curing agent were evenly mixed and reacted,a new sand consolidation agent was obtained. By using compression strength testing method of consolidated sand sample,the effect factors on sand consolidation performance of sand consolidation agent were analyzed,and the formula of sand consolidation agent was optimized. The results showed that the infrared spectrum of modified phenolic resin was characterized by the adsorption peak of —CH_3,—CH_2—,benzene（ Ph H）, 1,2,3-three replacing —CN— of Ph H and Ar —O—R, and the stretching vibration absorption of C—N,—N—H—,C—O of tertiary alcohol. The theoretical structure of the product was consistent with the actual structure. The mass ratio of fracturing sand,linear phenolic epoxy resin,curing agent and coupling agent（γ-aminopropyl triethoxy silane）in sand consolidation agent was 100∶6∶0.6∶0.1. The curing time was 48 hrs. The compressive strength of solidified body under this condition was 8.8 MPa,showing good sand consolidation performance.
