摘　　要：石油钻机井架作为典型的大型钢结构长期处于野外环境,经受风雨和冰冻侵蚀,搬运过程中的磕碰和挤压变形,长期积累造成井架主体结构损伤,严重影响到石油钻井的安全生产。实际上井架的实验研究受到现场施工环境和高成本制约。按照相似理论确定相似比系数,完成石油井架相似模型设计,通过模拟钻井工况,进行相似模型的承载力实验,获得结论推演真实结构的承载力分布规律。通过K型井架模型设计验证误差在10%之内。相似模型研究方法将为在役井架承载力评价,特别是未来沙漠钻机和深海钻机井架的承载力研究提供理论依据。The oil derrick is a special steel structure in oil field or rugged environment with wind,rain and freeze.The bump and extrusion in the movement can bring distortion to the derrick＇ s major structure and can produce serious influence on the safety production.The site operation environment and high cost always restrict the experimental study on the oil derrick in service.Designing similar model for the oil derrick based on similarity theory and similar coefficient was implemented,including the simulation of working conditions,the experiment on the load capacity and its distribution rule of the oil derrick.The error of the data from the model experiments is less than or equal to 10％ while comparing with that from the actual oil derrick.This study can provide theoretical basis to evaluating load capacity of the derrick in service,especially to that of the derrick in desert and deep sea.
