摘　　要：为了提高海上修井过程中封隔器磨套铣效率,保障作业的可靠性与经济性,通过研究影响磨套铣效率的主要因素,针对性引入了单头水力马达的螺杆钻具,配合捞杯和震击器等井下工具优化了磨套铣管柱结构,并基于此同步优化了关键施工参数设计方式,形成了一套海上油田螺杆钻具提高修井封隔器磨套铣效率工艺。该研究在南海西部北部湾12-1油田BX井修井过程中进行了应用,相对常规作业方式提高了近10倍的进尺效率,提速提效明显,为后续海上修井提高磨套铣效率提供了良好借鉴。In order to improve the milling efficiency of packer grinding sleeve in the process of offshore workover,and ensure the reliability and economy of the operation.By studying the main factors affecting the milling efficiency of the grinding sleeve,the screw drilling tool with a single head hydraulic motor was specifically introduced,and the structure of the grinding sleeve milling string was optimized with downhole tools such as the fishing cup and the jar.Based on this condition,the design method of key construction parameters was optimized synchronously,and a set of offshore oilfield screw drilling tools was formed to improve the milling efficiency of the workover packer.This study has been applied in the workover process of BX Well in the 12-1 Oilfield in Beibu Gulf of the western South China Sea.Compared with conventional operation methods,it improves the drilling efficiency by nearly 10 times,and the speed and efficiency are significantly improved,which provides good reference for improving the efficiency of grinding sleeve milling in subsequent offshore workover.
