Abstract:Aiming at the problems of sand production in shallow low-temperature formation and high water cut in oil wells, laboratory research on low-temperature solidified water blocking and oil permeability sand control materials was carried out. A sand control material was prepared by blending quartz sand, epoxy resin, relative permeability regulator and dispersant, and a curing agent was developed. The curing mechanism, thermal stability and micro morphology of coated sand and artificial core were analyzed by FT-IR, thermogravimetry and scanning electron microscope, and the compressive strength and water / oil permeability of artificial core were investigated. The experimental results show that under the condition of low temperature (30 ~ 70 ℃), the artificial core solidified with 30% relative permeability regulator has excellent compressive strength, more than 4.22mpa, and has certain oil-water selectivity. The water phase permeability and oil phase permeability are 963 and 5513 respectively × 10-3 μm2。
