Abstract: The speed destribution, flow rate and pressure gradient of liquid elastic wave across any section of pipeline in oilfield pipeline system are studied. The flow law and the radial movement theory of the particle are discussed on the high and low shear rate flow liquid. It is pointed out that the particle always moves forward the equilibrium positions around the 0.6 R(radius), and the moving speed is quicker as the Reynolds Number increases wherever the initial position of the particle is. Based on the combination with the theory and vibration pattern of liquid in pipeline system, the mechanism of the paraffin and scale control have been studied.
