摘要
根据二连阿南、哈南低渗透砂岩油田的地质和开发特征及造成油层污染的主要原因 ,研制了以溶蜡、胶质沥青为主的HB有机解堵剂配方和以清除酸溶盐、铁的腐蚀产物、粘土颗粒及乳化水堵塞为主的HB无机解堵剂配方。介绍了HB复合解堵技术解堵机理、解堵剂性能和现场施工工艺。在二连“两南”
According to the geology and the development characteristics and the main reason for production reservoir plugging in A'nan and Ha'nan low permeable reservoir of Erlian oilfield,HB organic and inorganic blockage removal agents are prepared.The former is mainly used to dissolve the wax,resin and asphaltene,the latter is mainly used to remove the dissoluble acid salt,iron corrosion product,clay particles and emulsifying water blockage.The HB composite blockage removal technology is presented,including the blockage removal mechanism,the blockage removal agent properties and the field use technology.The reservoir blockage removing treatments are performed 105 well times wiht effectiveness of 80% in A'nan and Ha'nan low permeable reservoir.
