一趟多层防砂技术是世界较为先进的技术,该技术与单层防砂相比,在套管的射孔段或裸眼段内的目的层下入一趟管柱,大大缩短了完井周期,提高了作业效率。但在实际操作中,密封件易被损坏,易出现验封效果不佳和砂卡等诸多问题。本文对这套防砂技术操作过程中易卡钻事故作出了详细的分析。
A multi-layer sand control technology is the world’s most advanced technology, the technology compared with the single-layer sand control, perforated section of the casing or the naked eye into the target layer into a trip under the column, greatly reducing the completion cycle, Improve work efficiency. However, in actual operation, the seal is easily damaged, prone to poor seal inspection and sand card and many other problems. This paper gives a detailed analysis of the easy-sticking accident during the operation of sand control technology.
