摘　　要：全球能源需求持续增长,尤其是石油和天然气等化石燃料。虽然每口井的石油和天然气产量都有下降的趋势,但如果这种情况继续下去,能源就会短缺。提高石油产量的一种方法是向油井注水。石油和天然气生产通常会产生大量的水作为副产品,称为采出水。采出水可用于注水,以提高石油产量,但采出水的参数必须符合质量标准,以避免损坏岩层、结垢、设备腐蚀和进一步污染。膜分离技术是气田水处理的一种替代技术,可以有效地去除原油,降低含盐量。纳米杂化聚醚砜(PES)膜是一种新型膜材料,具有显著推动当前技术发展的潜力。以聚醚砜和纳米二氧化硅为无机填料,在N-甲基吡咯烷酮溶剂中,采用干/湿相转化技术制备了均匀稳定的掺杂溶液,制备了纳米杂化膜。将该膜应用于采出水死细胞过滤系统。结果表明:纳米杂化膜对采出水的除油除盐能力高于常规膜,且纳米杂化膜具有较高的渗透性。Global energy demand continues to rise,especially for fossil fuels such as oil and natural gas.While the production of oil and gas per well is on a declining trend,if this continues,there will be an energy shortage.One method to increase oil production is water injection into oil wells.Oil and gas production typically generate a significant amount of water as a byproduct,known as produced water.Produced water can be used for water injection to enhance oil production,but the parameters of produced water must meet quality standards to avoid reservoir damage,scaling,equipment corrosion,and further pollution.Membrane separation technology is an alternative technique for gas field water treatment,effectively removing crude oil and reducing salt content.Nano-enhanced polyethersulfone(PES)hybrid membranes are a novel membrane material with the potential to significantly advance current technology.Uniform and stable doped solutions were prepared using polyethersulfone and nano silica as inorganic fillers in N-methyl-2-pyrrolidone solvent,utilizing dry/wet phase inversion techniques to fabricate nano-enhanced hybrid membranes.This membrane was applied to a produced water dead-end filtration system.Results show that the nano-enhanced hybrid membrane exhibits higher oil and salt removal capabilities from produced water compared to conventional membranes,and it demonstrates superior permeability.
