摘要
井下视像技术可获得直观、清晰的井下井筒图像,有助于快速识别井况并为后续作业提供相关信息和依据。针对鲁迈拉油田大斜度井在修井作业过程中存在的小井眼井筒尺寸限制、井况复杂、难以掌握井底实际情况等作业难题,引入了井下视像新技术,从作业管柱内下入井下视像工具对井筒进行实时检测和分析。多个方面的现场应用实例表明,井下视像技术在大斜度井的井筒检测、井况分析及打捞作业诸方面能够有效提高诊断精度及作业效率,缩短作业周期,降低作业成本。同时,井下视像技术对于观测井底落鱼及管柱损坏情况、检查射孔质量及分析井筒损坏机理等工作均具有一定的指导意义。
Downhole video technology can provide valuable wellbore information for the forward operations with its timely clear and stable images. In order to solve the downhole technical problems of wellbore diameter＇ s limitation and complex underground condition during workover operation in high angle well, the downhole video technology was introduced to obtain the necessary downhole wellbore real-time information in Rumaila Oilfield. The field applications showed that downhole video technology could provide an effective method to improve diagnostic accuracy and work efficiency, reduce operation time and cut the overall cost of workover operations in high angle well. The application also had a good guiding significance for investigating downhole fish or tubular condition, detecting perforation quality and analyzing the mechanism of wellbore damages.
