摘要
滑溜水体系技术广泛用于油气开采领域中,滑溜水体系的核心技术为减阻添加剂,用于降低压裂施工摩阻。对比分析了滑溜水减阻剂的降阻机理,综述了滑溜水减阻剂的研究进展,介绍了高矿化度水质对滑溜水降阻效果的影响及作用机理,主要包括静电屏蔽、压缩双电层等,总结出通过引入耐盐基团、疏水缔合性基团等方法可以提高减阻剂的耐盐性能,提出未来可通过有针对性地设计减阻剂分子合成方案,进一步优化滑溜水体系,增强滑溜水体系压裂液技术的适用性。
Slick water system technology is widely used in the field of oil and gas exploitation.The core technology of slick water system is drag reducing additive,which is used to reduce the friction of fracturing operation.The mechanism of reducing resistance of slick water drag reducer is compared and analyzed,the research progress of slick water drag reducer is summarized,the influence mechanism of high salinity water quality on the effect of slick water drag reduction is introduced,mainly including electrostatic shielding,compression electric double layer.It is concluded that the salt resistance of slick water drag reducer can be improved by introducing salt resistant groups and hydrophobic association groups.It is suggested that the molecular synthesis scheme of drag reducer can be designed to further optimize the slick water system and enhance the applicability of the slick water system fracturing fluid technology.
