| 摘 要： | 针对牛庄油田牛25区块低渗和粘土矿物含量高等特点,分别从改善注水水质以减小注水对地层的伤害和通过基质酸化以提高地层渗透率两方面对注水井增注技术进行了研究。污水对地层岩心的液测渗透率的损害率高达96.5%,而通过微孔滤膜过滤以及水质改性技术处理后的混合水对液测渗透率的损害率降为22.2%,研制的乙酸配方基质酸化后渗透率提高1861.5%。

| Abstract: | For the low permeability and high clay mineral content of 25 block of Niuzhuang oilfield.Respectively,we increase injection of the injection wells via the study of improving the injection water quality to reduce the water injection formation damage and matrix acidizing to enhance the formation permeability.The sewage damage of the formation cores to liquid measuring permeability reaches to 96.5 %,but it decreased to 22.2 % after the technical treatment of filter membrane and prevention of fouling .The penetration of acetate formulations after matrix acidizing increased 1 861.5 %. |
