钻探用四角管塔地面安拆技术研究

Study on Assembly and Disassembly Technologies of Quadrangular Tube Derrick on the Ground

摘要:

四角管塔地面安拆装置可实现在地面完成安装、拆卸四角钻塔的工作。从塔架顶层开始安装，顶层安装好后用升降机顶起一定高度，再安装下面一层。由上而下一层一层安装，工人可在地面完成安拆工作，避免工人高空安装、拆卸，提高安装效率，减少安装成本，降低安拆风险。

Abstract:

With assembling and disassembling devices of quadrangular tube derrick on the ground, the assembling and disassembling can be completed on the ground. The installation is started from the derrick top, this first part is lifted a certain height by elevator, then the next begins. The work can be operated on the ground to avoid the unsafe factors to improve working efficiency and reduce installation cost.
