腐蚀管柱打捞方法研究

Research on Corroded String Fishing Methods

油田勘探开发中,由于地质和工艺等方面原因,井内管柱出现不同程度的腐蚀变形,造成油、水井不能正常生产,大幅降低油井产量,严重的可能致使油、水井报废。通过分析腐蚀管住打捞的技术难点,针对性地提出进行油、水井维护作业和井内管柱的打捞更换方法、建议,以保障正常生产。

In oilfield exploration and development,strings inside wells undergoes varying degrees of corrosion and de-formation due to geological and technical reasons,leading to the shutdown of oil and water wells,significantly reducing oil production,and in severe cases,resulting in the scrapping of these wells.By analyzing the technical difficulties in fishing corroded strings,specific maintenance operations for oil and water wells and methods for fishing and replacing the strings are proposed to ensure normal production.
