摘要: 在曹妃甸11⁃2油田高含水水平井实施酸化措施后,效果不佳,为提高作业效果,对酸液体系和施工参数进行了针对性优化。酸液体系优选实验结果发现,土酸溶蚀能力高于氟硼酸和多氢酸,而多氢酸缓速能力明显优于土酸和氟硼酸;施工参数模拟结果表明,提高注酸速度有助于提高酸化效果,解堵半径1~2 m即可有效解除储层污染。首次将溶蚀能力强的土酸和缓速能力高的多氢酸在曹妃甸11⁃2油田三口井酸化作业中综合使用,现场施工后三口井平均单井日增液362 m3/d,平均单井日增油16.4 m3/d,解堵增产效果显著。

Abstract: Several studies have been done on the acid system and acidizing operation parameters in order to improve acidizing effect on high water⁃cut horizontal well of CFD11⁃2 oilfield.The results show that the corrosion capacity to rock of mud acid is higher than fluoroboric acid and muti⁃hydrogen acid,while the retard capacity to rock of muti⁃hydrogen acid is superior to mud acid and fluoroboric acid.The results by simulate on acidizing operation parameters show that high injection rate is favorable to improving acidizing effect,and the pollution can be removed effectively when acidizing radius is 1~2 m.Soil acid with strong dissolution ability and polyhydrogen acid with high retardation ability were firstly used in acidizing operation of three wells in Caofeidian 11⁃2 oilfield.After field operation,the average daily fluid increment of three wells was 362 m3/d,and the average daily oil increment of single well was 16.4 m3/d.The effect of plugging removal and stimulation was remarkable.
