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.
