【摘要】：在全世界的油气田中,修井机均是起下输油管柱以及改换井下采油设备不可缺少的必要设施,为我国实现现代化建设,提高GDP等方面起到了至关重要的作用。由于修井机作业现场主要集中在室外,且其中不乏森林、沙漠等自然条件艰苦的地区,现场情况相当复杂。而井架系统又是整个修井机的主要承载部件,所以设计时应尽量保证尽善尽美,这样既能减少材料的的浪费,又可以最大程度避免事故的发生。因此,必须对修井架系统采取全面、准确、详尽的综合分析。经过分析找出修井架系统的薄弱环节,有的放矢的进行改进、强化,最大程度的保证施工安全。通过对国内外修井机设计及使用资料进行充分分析后,对原有修井机井架系统进行改进,设计出了一种具有一定创新性的先进车载式不压井修井机井架系统的设计方案,并建立3D数学模型,利用有限元法对井架系统的关键部位进行静力学分析,如井架系统的支撑轴、井架平移系统的接触面。通过分析验证了井架系统设计方案的可行性,并对井架系统的优化设计提供依据。本文在对井架系统进行静力学分析的同时,也对井架系统的翻转过程进行了动力学模拟分析。通过分析较为真实的再现了井架系统在翻转过程中系统的受力变化情况,获得了一些关键性数据,验证了井架系统在翻转过程中的安全性与可靠新,使井架系统的力学分析更为全面。
[Abstract]:In oil and gas fields all over the world, workover machines are indispensable facilities for starting and lowering oil transmission lines and changing downhole oil production equipment, so as to realize the modernization of our country. The improvement of GDP has played an important role. Because the workover machine works mainly outside, and there are many of them, such as forests, deserts and other areas where natural conditions are difficult, The field situation is quite complicated, and the Derrick system is the main bearing part of the workover machine, so the design should be as perfect as possible, which can not only reduce the waste of materials, but also avoid the accident to the greatest extent. We must take a comprehensive, accurate and detailed comprehensive analysis of the Derrick repair system. Through the analysis, we should find out the weak links of the workover Derrick system, and improve and strengthen the Derrick system in a targeted way. By analyzing the design and application data of workover machine at home and abroad, the Derrick system of original workover machine is improved. The design scheme of the Derrick system of an advanced vehicle-borne workover machine is designed, and the 3D mathematical model is established. The statics analysis of the key parts of the Derrick system is carried out by using the finite element method. For example, the supporting shaft of Derrick system and the contact surface of Derrick translation system. The feasibility of Derrick system design scheme is verified by analysis, and the basis for the optimum design of Derrick system is provided. In this paper, statics analysis of Derrick system is carried out at the same time. The dynamic simulation analysis of the turnover process of the Derrick system is also carried out. Through the analysis of the actual reappearance of the mechanical changes of the Derrick system during the turnover process, some key data are obtained. The safety and reliability of the Derrick system in the turning process are verified, and the mechanical analysis of the Derrick system is more comprehensive.
