摘要
为助力我国超深地层科学探索和万米以上深层油气发现,研制了2套12000 m特深井自动化钻机.该钻机配套15 m超高钻台底座、4600 kW高载重比绞车、3000 hp五缸钻井泵组、9000 kN交流变频顶部驱动装置等,满足万米超高压复杂井钻井作业需要;配套超大容量管柱自动化处理设备及集成控制系统,满足万米钻具自动化存储和排放要求,实现了管柱从堆场到井口的全流程作业自动化;全面应用电动驱动设备,控制更精准,运行更环保,低温环境适应能力强,安全性更高;顶部驱动装置、发电机组、国产变频器全面替代进口,国产化程度高.钻机现场应用效果表明:两套12000 m特深井自动化钻机综合钻井速度达到1.6 m/h,起下钻速度24.8柱/h,通过远程在线检测及专家诊断系统使钻机的平均故障率较在役石油钻机降低50%,可减少钻井作业人员3人/班,人员劳动强度大大降低.为我国万米级地层的油气田开发提供了装备保障.
Abstract
In order to help the scientific exploration of ultra-deep formation and oil and gas discovery over 10000m in China,two sets of automatic drilling rig for 12000m extra-deep wells were developed which is equipped with 15m ultra-high drilling floor base,4600kW winch with high load ratio,3000hp five-cylinder drilling pump set,9000kN AC frequency conversion top drive device,etc.,to meet the needs of drilling operations for myriametric wells with ultra-high pressure complex condition.Ultra-large capacity pipe string automatic processing equipment and integrated control system are accompanied to meet the requirements of automatic storage and discharge of myriametric drilling tool,the full automated process of pipe string from the yard to the wellhead was achieved.Electric drive equipments were comprehensively applied with more accurate control,more environment friendly operation,low temperature environment adaptability and higher safety.Equipements such as top drive device,generator set and domestic inverter are locally made rather than imported.The field application showed that the two sets of automatic drilling rig for 12000m extra-deep wells has an integrated drilling speed of up to 1.6m/h,and the tripping speed is 24.8columns/h.Through the remote online detection and expert diagnosis system,the average failure rate is reduced by 50%compared with the in-service drilling rig,and the drilling operator can be reduced by 3 people/shift,as a result,the labor intensity of drilling personnel can be greatly reduced.It provides equipment support for China's oil and gas field development in myriametric formations.
