摘要
合适的抗盐聚合物性能指标是高盐油藏提高采收率的重要物质基础。针对八面河油田储层地层水矿化度高、原油粘度高等条件,通过聚合物室内评价实验,研究了聚合物的增粘性、抗盐性、稳定性,以及聚合物的驱油效率。结果表明,面1区沙三上油藏合适聚合物溶液粘度为16mPa.s～24mPa.s,评价的KYPAM-6聚合物具有增粘性好、抗盐性强,在加入稳定剂SC后体系的稳定性得到改善。
The right property indicator of salt resistance polymer is the premise of better recovery ratio of salt--rich reservoirs. This paper studies polymers＂ properties such as viscosity--promoting, salt resistance, stability and displacement efficiency according to a laboratory evaluation experiment conducted based on the characteristics of Baminahe reservoirs such as high stratum water salinity and oil viscosity. The results showed that the proper polymer solution viscosity for Mian No. one district Shasan upper reservoir is 16 mPaos-24 mPaos and the targeted KYPAM --6 polymer dose well in viscosity--promoting and salt resisting and its stableness is enhanced once blended with stabilizer SC.
