本文结合渤海油田实际,经过分析优化,探索并形成了一套基于受限空间的井槽再造钻完井技术,主要包括隔水导管重置技术、单筒双井技术、外挂内挂槽口与双层套管开窗技术等.应用效果表明,基于受限空间的井槽再造钻完井技术有效解决了渤海油田现有槽口利用中存在的问题,取得了良好效益,为渤海油田稳产增产奠定了基础.%Based on the actual situation of the Bohai Oilfield,this paper has explored and formed a set of drilling and completion technologies for drilling wells based on confined space. The main technologies include the resetting technique of the traps,single-tube double-well technology,outer hanging slot and double casing windowing technology. The application results show that the well drilling and completion technology based on confined space effectively solves the existing problems in the utilization of the existing notches in Bohai Oilfield,and has achieved good results,laying a solid foundation for stable production and yield increase in Bohai Oilfield.
