【摘要】：在油田的修井及增采作业中,修井机是比不可少的装备,我国每年要进行十多万次的各类修井和增产措施作业。修井机在作业时除了承受自身恒载外,还要承受提放钻具的大钩载荷,风载绷绳上的风载以及修井机振动时产生的振动载荷等,在这些载荷作用下修井机的稳定性尤为重要。井架是修井机的关键部件,承受主要的载荷。修井机在完成修井作业过程中,特别是起下管柱末时,刹车会带来很大的载荷,即冲击,此刻会有比较大的额外动载荷作用在井架系统上,这会使其发生强烈的振动。因此若井架系统制造不合理,不但会对材料造成损失,而且在作业时会导致失效,严重则产生事故。本文以XJ250轮式作业机为研究对象,针对其在现场作业时出现的车头翘起和侧翻的稳定性问题,计算了其极限钩载,并借助ANSYS软件对整机进行建模,模拟其工作中的受力状态。对其进行了静力学分析、结构模态分析、稳定性分析以及非线性分析。总结了造成XJ250作业机失稳的原因,为其优化设计提供了理论依据。
[Abstract]:In oil field workover and production increase operation, workover machine is more than necessary equipment, our country must carry on various kinds of workover and production increase measure operation more than 100,000 times every year. The workover machine not only bears the dead load of itself, but also bears the hook load of lifting drilling tool, the wind load on the wind-loaded tension line and the vibration load caused by the vibration of workover rig. The stability of workover rig under these loads is particularly important. Derrick is the key component of workover machine and bears the main load. When the workover machine completes the workover operation, especially when the pipe string is up and down, the brake will bring a great load, that is, impact, and at the moment there will be a relatively large additional dynamic load acting on the Derrick system, which will make it vibrate strongly. Therefore, if the manufacture of Derrick system is not reasonable, it will not only cause loss to material, but also lead to failure and serious accident. In this paper, the ultimate hook load of XJ250 wheeled machine is calculated in view of the stability problem of the turning head and rollover which occurs in the field work, and the whole machine is modeled by ANSYS software to simulate the force state in its work. Statics analysis, structural modal analysis, stability analysis and nonlinear analysis are carried out. The causes of the instability of XJ 250 operating machine are summarized and the theoretical basis for its optimal design is provided.
