摘　　要：井架作为石油钻机设备的关键部分,其承载能力直接关系到整个钻井作业施工的安全,而现场技术人员难以应用通用计算机仿真软件直接对井架进行力学强度、稳定性和安全评价。针对上述问题,在Visual Basic 2010开发平台的基础上,通过APDL程序语言对ANSYS软件进行二次开发,核心是在不进入ANSYS软件界面情况下,所开发软件能够跟踪ANSYS解算器的整个运行过程,提取相关的计算结果数据和ANSYS图形显示数据。运用开发的钻机井架安全性可视化仿真软件可以直观显示井架各个部位的应力、应变和位移云图,也可以提取关键位置点的最大应力、应变和位移数值,为井架安全性评价提供简便而可靠的手段。利用上述软件开发成果对现场井架安全性评价,分析了井架的危险点位置、最大承载能力及井架的失稳状态,结果表明,上述软件可以为石油井架安全性评价提供依据。As the key part of drilling equipment,the safety evaluation of derrick is close related to the safety of drilling operation. However,technicians in the field can hardly master and apply ANSYS software to mechanical,stability and safety evaluation. A visual simulation software of derrick was developed in this paper by making ANSYS with secondary development based on the Visual Basic 2010 platform. The software can track the whole running process of ANSYS solver directly,and extract the calculating result data and graphic of ANSYS data,but not enter the ANSYS software interface. A finite element model library of four kinds of K type derricks was established in the software. And the stress,strain and displacement nephogram of all parts of derrick can be visually displayed and the maximum stress,strain and displacement of the key place can be extracted in development software. Now the software has been widespread used in field safety evaluation of derrick.
