摘要

受油井超深、地层腐蚀流体、高温高压、电化学腐蚀、修井损伤等综合因素影响，塔河油田油管腐蚀断裂现象逐年增多，给修井打捞作业造成了诸多困难。通过采取针对严重腐蚀管柱的打捞工艺，根据不同井深落鱼状况，选择合适的井下工具，合理控制现场工艺参数，T801（K）井腐蚀油管打捞成功，为严重腐蚀管柱打捞作业提供了经验借鉴。

Abstract

Due to ultra depth of wells, formation fluid corroding,HTHP, electrochemical corroding, workover damage, etc. , the corrosion and fracture of tubings in the Tahe Oilfield are increasing year by year, which bring a lot of troubles in the fishing process. Based on special fishing measures, proper choice of tools and reasonable technological parameters according to downhole conditions, the corroded tubings in well T801(K) have been fished successfully. This provides good experience to fish severely-corroded tubing.
