| Abstract: | This paper studies Theoretically the affection of flowing Velocity of drilling fluids on the lateral vibration of the drilling string.A welleonsidered differential equation of the lateral vibration of the drilling string is built.A formula between the inherent frequency and the flowing velocity of drilling fluids is given,and the developing process of drilling string from vibration to unstable state by the change of the flowing velocity of drilling fluids is discussed.The mechanism of the affection is analysed and discussed. |
