摘　　要：综合录井仪器房是仪器的机械支撑框架,其结构性能的优劣直接影响到录井仪器使用中的有效性和安全性。结构设计的缺陷和不均衡受力状况都可能导致仪器房框架结构的变形甚至损毁,导致仪器设备脱落或损坏。对仪器房进行有限元仿真分析可以了解和掌握在承载状态下仪器房的形变情况。给出了模型及求解方法和边界条件数值等,试用后证实仿真分析结果是仪器房变形与安全系数分布和现场实际相吻合,可用于改进仪器房结构设计和指导正确使用。Comprehensive mud logging unit house is the mechanical supporting frame for instruments, the quality of the structural features will directly affect the effectiveness and safety during the use of the logging instruments. The defects and uneven force subjecting condition of the structural design may cause the deformation and damage of the unit frames, resulting in dropping and damaging of the instruments. Carrying out the limit element analysis on logging units can understand and grasp the deformation state of the unit under loading condition. The paper gave out the model, the extraction method and the border situation values. Emulation analysis result was that the instrument deformation and safety factor distribution are fitted with site real condition.
