【摘要】：現(xiàn)代地質和石油鉆井中,鉆孔深度越來越大、水平井等新型鉆井技術越來越多的運用在鉆井作業(yè)的現(xiàn)場施工中,這對井下動力鉆具的性能要求更高。井下動力鉆具的應用可以起到改善鉆頭驅動方式、完善井身質量、提高鉆井效率等積極作用。支承節(jié)是井下動力鉆具的關鍵部件之一,它銜接鉆頭和鉆具動力節(jié),其使用壽命是制約井下動力鉆具正常使用的重要因素。針對井底非圓齒輪馬達設計了與之匹配的支承節(jié),旨在實現(xiàn)將非圓齒輪馬達技術應用于改善井底動力鉆具。結合現(xiàn)有的非圓齒輪馬達動力節(jié)結構,對支承節(jié)進行結構設計和關鍵部件靜力學仿真。具體工作內容如下:首先,對幾種成熟的井下動力鉆具,特別是井底非圓行星齒輪馬達的國內、外研究現(xiàn)狀進行調研,闡述了本文研究內容和意義。根據支承節(jié)設計要求,確定了其整體結構及工作原理,運用Solidworks仿真軟件,建立了實體三維模型。其次,對支承節(jié)的主要部件進行力學分析及強度校核,并通過SolidWorks Simulation模塊對馬達關鍵部件的受力情況進行模擬仿真,得到部件的應力和變形情況,驗證了零件設計的可靠性。最后,繪制孔底非圓齒輪馬達支承節(jié)二維圖紙,并對研究成果進行總結,為日后支承節(jié)的加工、改進及完善工作提供參考建議。
[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.
