Design and Finite Element Analysis of New Drilling Speed Magnetic Actuator

摘要: 针对定向井滑动钻进过程中的摩阻问题，提出一种新型基于径向振动的钻井提速磁激励器结构设计方法。通过理论计算和有限元软件ABAQUS对关键零部件波纹管振子进行模态分析，得到了振子径向振动频率的理论值和仿真值分别为36.29、38 Hz，两者相近且均在25～40 Hz的工况范围内，证明了结构设计满足要求；对其进行瞬态分析，得到了振子在周期性径向载荷下能够产生共振，证明了设计的可行性。

Abstract: Aiming at the friction problem during slide drilling of directional well, a new type of drilling speed magnetic actuator design method based on radial vibration is proposed. Through theoretical analysis and finite element software ABAQUS, the modal analysis of the bellows vibrator of key components was carried out, the theoretical value of the radial vibration frequency of the vibrator was 36.29 Hz and the simulation value was 38 Hz, both were similar and within the working range of 25 Hz to 40 Hz, which proved that the structural design meets the requirements; transient analysis of the vibrator shows that the vibrator can generate resonance under periodic radial loads, the feasibility of the design is proved.
