【摘要】：现代地质和石油钻井中,钻孔深度越来越大、水平井等新型钻井技术越来越多的运用在钻井作业的现场施工中,这对井下动力钻具的性能要求更高。井下动力钻具的应用可以起到改善钻头驱动方式、完善井身质量、提高钻井效率等积极作用。支承节是井下动力钻具的关键部件之一,它衔接钻头和钻具动力节,其使用寿命是制约井下动力钻具正常使用的重要因素。针对井底非圆齿轮马达设计了与之匹配的支承节,旨在实现将非圆齿轮马达技术应用于改善井底动力钻具。结合现有的非圆齿轮马达动力节结构,对支承节进行结构设计和关键部件静力学仿真。具体工作内容如下:首先,对几种成熟的井下动力钻具,特别是井底非圆行星齿轮马达的国内、外研究现状进行调研,阐述了本文研究内容和意义。根据支承节设计要求,确定了其整体结构及工作原理,运用Solidworks仿真软件,建立了实体三维模型。其次,对支承节的主要部件进行力学分析及强度校核,并通过SolidWorks Simulation模块对马达关键部件的受力情况进行模拟仿真,得到部件的应力和变形情况,验证了零件设计的可靠性。最后,绘制孔底非圆齿轮马达支承节二维图纸,并对研究成果进行总结,为日后支承节的加工、改进及完善工作提供参考建议。
[Abstract]:In modern geology and petroleum drilling, drilling depth is getting deeper and deeper, and new drilling techniques such as horizontal wells are more and more used in the field operation of drilling operations, which requires higher performance of downhole power drilling tools. The application of downhole power drilling tools can improve the driving mode of drill bit, improve well quality and improve drilling efficiency. The supporting joint is one of the key parts of the downhole power drilling tool, which connects the drill bit and the drill tool power section, and its service life is an important factor that restricts the normal use of the downhole power drill tool. In order to realize the application of the non-circular gear motor technology to improve the bottom hole power drilling tool, a matching supporting node is designed for the bottom hole non-circular gear motor. Combined with the existing structure of non-circular gear motor, the structural design and statics simulation of the key components are carried out. The specific work is as follows: first, the domestic and external research status of several mature downhole power drilling tools, especially the bottom hole non-circular planetary gear motor, is investigated, and the research content and significance of this paper are expounded. According to the design requirements of the supporting section, the whole structure and working principle are determined, and the solid 3D model is established by using the Solidworks simulation software. Secondly, the mechanical analysis and strength check of the main parts of the supporting joint are carried out, and the stress and deformation of the key parts of the motor are simulated by the SolidWorks Simulation module, which verifies the reliability of the design of the parts. Finally, the two-dimensional drawing of the supporting section of the non-circular gear motor with hole bottom is drawn, and the research results are summarized, which provides some reference suggestions for the processing, improvement and improvement of the supporting joint in the future.
