“混沌理论”与“蝴蝶效应”视角下的油井杆管偏磨

Oil Well Rod Tube Eccentric Wear Based on "Chaos Theory" and "Butterfly Effect"

从"混沌理论"与"蝴蝶效应"视角探讨杆管偏磨的混沌分析与控制,识别杆管偏磨的混沌吸引子,抑制或消除杆管偏磨某些类型的混沌,稳定控制混沌吸引子中的不稳定周期态,消除多重混沌吸引子流域以达到新的动力学平衡,有效防止油井杆管偏磨。

This paper discusses chaos analysis and controllment of rod tube eccentric wear based on ＂Chaos Theory＂ and ＂Butterfly Effect＂.It identifies chaotic attractor and restrains or eliminates the chaos.At the same time,it controls unstable period in chaotic attractor,and eliminates multiple chaotic attractor to reach new dynamic balance so as to prevent oil well rod tube eccentric wear.
