3000 hp丛式井钻机导轨双向移运技术研究

Research on Two-way Guide Rail Moving of 3000 hp Cluster Well Rig

针对国外某人工岛作业区域布置,分析超深丛式井钻机移运装置特性,研究针对该区域的导轨双向移运方案。通过计算钻机底座在纵横向移运过程中的力学特性,分析钻机"门"形连接架强度可靠性。并针对作业区域井口远距离运输等特点,研究远距离电缆存储技术,分析并计算钻机主机设备电缆压降,为电缆远距离信号间的相互干扰问题提供解决方案。

Based on the arrangement of a foreign artificial island well drilling,the characteristics of the ultra-deep cluster well rig moving devices are analyzed,and the two-way guide rail moving schemes are studied.Then the rig substructure mechanical characteristic is calculated,and the strength reliability of the portal frame connector during rig moving is analyzed.According to the long-distance well distance,the cable storage is researched,and voltage drop of cable is calculated.Then the solutions for the cable signals mutual interference are provided.
