In a view to comprehensively analyzing characteristics of the medium fluid field within the longdistance pipeline,to obtain its optimal parameters and improve its oil-transporting efficiency,a new method for analyzing the characteristics there was proposed.Through making use of the analysis method of flow characteristics of petroleum and crude oil,the flowmeter coefficients'interference factors and its synthetic factors were analyzed to obtain the flow characteristics of petroleum and crude oil.Meanwhile,through adopting the pipeline's measurement and transmission analysis method,both standard volume's and standard density's error of oil products were calculated and the turbulence model and the initial boundary value conditions were combined to construct the transport equation for both turbulence and turbulence energy dissipation so that the fluid field characteristics of petroleum and crude oil can be obtained.The experimental results showed that,when the cyclone's inlet form of the long-distance pipeline is rectangular,the diameter of the overflow outlet is 5.5mm,and the length of the swirl cavity is 71mm,the error between long-distance pipeline's calculation and actual value of both standard volume and viscosity coefficient are extremely small.
