【摘要】：铁钻工在石油机械及大陆钻探领域中是一种自动化、智能化的钻具上/卸扣设备。智能化铁钻工的研制对科学钻探迈向现代化进程有着积极的意义[1]。本文研究的课题“铁钻工自适应技术的研究”就是在这样的大背景下开展的。为了进一步提高钻具上扣连接的自动化、智能化程度,本文对铁钻工拧卸钻具的自适应性装置进行研究。铁钻工自适应性程度的高低直接影响到钻杆连接和卸扣的工作效率和适应范围,具有重要的现实意义[2]。本文结合“深部探测技术与实验研究专项”项目,以铁钻工的关键部件旋扣机构为研究对象,分析铁钻工旋扣机构在钻杆夹持过程中的自适应性。具体内容如下:首先,查阅国内外铁钻工文献。针对本文研究的自适应问题,整理和总结了铁钻工自适应调整机构的发展现状。从机构的自适应性角度出发,归纳出本文的研究内容,对旋扣调整机构完成结构设计,并用Inventor建模。再次,对旋扣机构夹持钻具的运动过程进行分析。将钻具夹持过程分为两个阶段:活塞杆伸出阶段和夹持调整阶段。对夹持过程的两个阶段进行旋扣机构运动学分析。分析钻具在调整机构的作用下最终的夹持状态,求解不同规格钻具的夹持角。通过对上下浮动装置的力学分析,设计了上下浮动油缸的关键性能参数。然后,使用ADAMS建立旋扣总成机构的仿真模型,对旋扣机构夹持钻具的自适应调整过程进行运动学仿真。通过对旋扣机构仿真参数曲线的分析,将理论和仿真结果对比,验证旋扣机构理论调整过程的正确性和可行性。运用Workbench对旋扣机构的关键受力结构仿真分析。对旋扣机构的夹紧臂、横梁支撑件,限位轮销轴进行有限元分析。研究它们的静力学特性,得到其应力分布和变形量,验证结构的合理性。最后,对铁钻工样机的旋扣机构进行试验。观察和记录旋扣机构的抱合动作以及对不同直径规格钻具的夹持过程。采集并分析试验数据,验证旋扣机构夹持过程运动学建模的正确性。
[Abstract]:Iron rigs are an automatic and intelligent drilling / unlocking equipment in the field of petroleum machinery and continental drilling.The development of intelligent iron drillers has positive significance in the process of scientific drilling towards modernization.The research topic of this paper is the study of iron-drill adaptive technology, which is carried out under such a background.In order to further improve the automation and intelligence of the upper buckle connection of drilling tools, this paper studies the self-adaptive device of the iron-drilling rig for screwing and unloading drilling tools.The degree of self-adaptability of iron-drillers has a direct impact on the working efficiency and adaptability range of drill pipe connection and disconnect, which has important practical significance [2].In this paper, based on the project of "deep detection technology and experimental research", the self-adaptability of iron drill rotary mechanism in the process of drill pipe clamping is analyzed by taking the key component of iron drill as the research object.The concrete content is as follows: first, consult the domestic and foreign ironwork literature.Aiming at the adaptive problem studied in this paper, the development status of the adaptive adjusting mechanism of iron drill is summarized.From the point of view of self-adaptability of mechanism, the research contents of this paper are summarized, and the structure design of the mechanism is completed, and the model is modeled by Inventor.Thirdly, the movement process of clamping drill tool is analyzed.The clamping process is divided into two stages: piston rod extension stage and clamping adjustment stage.Kinematics analysis of the two stages of the clamping process is carried out.The final clamping state of drilling tools under the action of adjusting mechanism is analyzed, and the clamping angle of different specifications of drilling tools is solved.The key performance parameters of the upper and lower floating cylinder are designed through the mechanical analysis of the upper and lower floating device.Then, ADAMS is used to establish the simulation model of the rotary assembly mechanism, and the kinematics simulation of the adaptive adjusting process of the clamping drill tool of the rotary mechanism is carried out.Through the analysis of the simulation parameter curve of the rotary mechanism, the correctness and feasibility of the theoretical adjustment process of the mechanism are verified by comparing the theoretical results with the simulation results.Workbench is used to simulate and analyze the key force structure of the mechanism.Finite element analysis of clamping arm, beam support and limit wheel pin shaft is carried out.Their static properties are studied, and the stress distribution and deformation are obtained to verify the rationality of the structure.Finally, the rotary mechanism of the iron drill prototype is tested.Observe and record the clamping movement and clamping process of different diameters of drilling tools.The experimental data were collected and analyzed to verify the correctness of kinematic modeling of clamping process of the mechanism.
