摘要: 针对树脂固砂剂一直存在固砂强度与地层渗透率保留率之间的矛盾,开展了磷酸酯改性呋喃树脂固砂剂的研究,研究中以磷酸、聚醚(L35)、呋喃树脂为主要原料,通过羟基缩聚制备出磷酸酯改性呋喃树脂水性聚合物,并将其用水稀释3倍后作为油田固砂剂使用,一方面,以水作为天然增孔剂,另一方面,在水环境下成膜固化,既保证了固砂强度,又保证了高地层渗透率,有效解决了长期困扰化学防砂效果的难题。研究结果表明,磷酸酯改性呋喃树脂用水稀释3倍浸入砂粒后,于水下环境中60~80℃保温48 h可固结砂粒,固砂强度大于4 MPa,适合油田水下环境固砂。截至2019年3月,现场应用10口油井,控砂成功率达100%,累计增油13 000 t,应用效果良好。

Abstract: The study aimed at the contradiction between the strength of sand consolidation and the retention rate of formation permeability. Phosphate modified furan resin sand consolidation agent was prepared by hydroxyl polycondensation with phosphate, polyether (L35) and furan resin as main raw materials, and it was used as sand consolidation agent after dilution with water on ratio 1: 3. On the one hand, water was used as natural pore increasing agent, on the other hand, sand consolidation agent film was formed and solidified in water environment, which guaranteed compressive strength and high formation permeability. It effectively solves the difficult problem that puzzles the sand consolidation effect of chemical method for a long time. The results show that the phosphate modified furan resin can be consolidated at 60 ℃ for 48 h after dilute with water for 3 times. The compressive strength is above 4 MPa. It is suitable for sand consolidation in underwater environment of oil field. By March 2019, phosphate modified furan resin sand consolidation agent had been used in 10 wells in oilfield, with a 100% success rate of sand control and acumulative oil increase of 13 000 t. It has obtained the good effect in the practical application.

Key words: sand control, phosphate ester, furan resin, water-base sand consolidation agent, permeability
