摘要
土库曼斯坦Y气田地质与工程条件极其复杂,现存的6口探井至今已封井10年以上,井中套管腐蚀损伤情况对其修复投产具有重要影响。英国SONDEX公司MIT/MTT组合测井仪对检测套管内径和壁厚的变化有很高的诊断能力,可以准确识别射孔井段,套管损伤及变形的位置与程度等重要信息,为修井投产提供有利保障。MIT/MTT的解释结论还反映了不同类型套管的抗腐蚀能力,为后期新井的套管类型选择提供参考。
The geological and engineering conditions are very complicated in gasfield Y of Turkmenistan.The current six exploration wells have been closed for more than ten years,and down hole casing damage and corrosion situation is unknown,which is critical on whether these wells can be repaired to resume production.MIT/MTT combined logging tool,invented by SONDEX Company in UK,can detect casing caliper and wall thickness change with high accuracy to further identify the information of perforation interval,casing damage position and degree,casing deformation position and extent,which can supply reliable proofs for well-repairing measures.MIT/MTT logging analysis results can reflect corrosion resistant capacity of different type casing,which indicates the suitable casing type that should be adopted in the new drilling wells.
