摘要: 单一的防砂技术在稠油热采井中的应用受到一定限制,为解决热采井防细粉砂,从改善纤维复合防砂技术体系中的基体(树脂涂敷砂)性能入手,以期使纤维复合防砂技术能够用于热采井防砂。通过考察水溶性酚醛树脂、ER树脂粉末、偶联剂、增强剂加量对砂体抗压强度和渗透率的影响,分析了体系中各组分的作用机理。通过室内实验优化了纤维防砂体的配方,研究表明,偶联剂、改性剂、增强剂、ER树脂粉末、水溶性酚醛树脂SR1、石英砂之间的质量比为(0.15~0.20)∶3.1∶1.5∶(2~4)∶10∶100时体系具有较高的防砂强度,并且在350℃下仍能保持在3MPa左右,较不加入纤维时高30%,渗透率可增加10%左右。

Abstract: Single sand control technique has its limitations when applied to the thermal recovery heavy oil wells.Property of resin coated sand in fiber-complex sand control technique system is improved in order to apply fiber-complex sand control technique to the thermal recovery wells to prevent fine-silty sand production.Compressive strength and permeability are taken as indicators,effect of concentration of water soluble phenol-formaldehyde resin,ER resin powder,coupling agent and strengthening agent on strength of resin coated sand are researched,and function mechanism of components among the systems is analyzed.Mass ratio among coupling agent,modifier,strengthening agent,ER resin powder,water soluble phenol-formaldehyde resin SR-1 and quartz sand of typical fiber-complex formulation in the thermal recovery heavy oil wells is (0.15~0.20)∶3.1∶1.5∶(2~4)∶10∶100.The result of experiment indicates that strength of fiber-complex at 350℃ still remains about 3MPa,which is 30% higher than strength of resin coated sand without fiber,and permeability of resin coated sand is improved about 10% after fiber added.
