摘要
针对段六拨油田储层低渗、水敏严重引起的注水井注水压力高、注水困难的问题,应用“压裂造缝+酸化解堵溶蚀+连续防膨”技术,解决了13口井注水困难的问题,实现了日增注494 m3,累计增注21.3×104m3,措施有效率100%。为低渗油田注清水引起的储层伤害提出了解决措施,具有推广利用价值。
Reservoirs in Duanliubo Oilfield are low permeable and highly water-sensitive,thus resulting in high injection pressure and water injection problem.The technology of 'fracturing+acid deplugging+continuous antiswelling' has solved the water injection problems in 13 wells,realized a daily injection of 494 m^3,cumulative injection increment of 21.3×10~4 m^3,with success ratio of 100%. This eliminates the reservoir damage resulted from fresh water injection in low permeability reservoirs and is worth of spreading.
