【摘要】 针对传统单井架海上钻井平台、钻探船作业时，无法同时完成其他并行辅助管线的连接、下放作业问题，提出了月池区离线作业思路，通过在月池区防喷器台车上加装可以提升、下放、悬持管线的动力装置，配合原钻机系统配套的猫道机、排管机、铁钻工等设备，实现在月池区接装、下放、悬持钻杆柱、套管柱及其他管串。使得海洋单井架钻井平台和钻探船在原井口进行正常钻井作业的同时，可以在月池区并行接装管串，实现并行作业，节省大量的钻井辅助作业时间，极大降低钻井成本。更多还原

【Abstract】 When traditional single derrick drilling platforms and drilling vessels working, the connection and lowering of other parallel auxiliary pipelines are unable to simultaneously complete, therefore, a concept of offline operation in the moon-pool area is proposed. A power device on the blowout preventer trolley in the moon-pool area is installed which can lift, lower, and suspend pipelines. Combined with the original drilling system’s supporting equipment such as catwalk machines, pipe racking machines, and iron roughneck, the installation, lowering, and suspend drill string, casing string, and other pipe strings in the moon-pool area can be achieved. As a result, when the ocean single derrick drilling platforms and drilling vessels working, the connection of pipe strings in the moon-pool area can be operated parallelly, which can save a lot of drilling auxiliary operation time and greatly reduce the drilling cost.更多还原
