摘要:
自2016年11月以来,SD油田生产戴南组的油井已累计出现12口套损,严重影响了SD油田的正常生产。分析套损井生产特征及腐蚀情况,确定硫酸盐还原菌是引起套损的主要原因。优选了生物防腐技术和双封卡采工艺预防和治理套损井,现场应用取得了良好效果,降低了腐蚀速率,套损井恢复正常生产,工艺成功率100%。
Abstract:
Since November 2016,there have appeared 12 casing-damage wells in the Dainan Formation of SD Oilfield,which have a strong impact on the normal production of SD Oilfield.Based on the analysis of production characteristics and corrosion situation of casing-damage wells,it was found that sulfate reducing bacteria(SRB)was the main cause of casing damage.The biological anticorrosion technology and double-seal stick production technology were optimized to prevent and control casing-damage wells. Field applications have obtained good results,where there is a reducing corrosion rate,returning casing-damage wells into normal production, and a success rate of 100%.
