A new calculation model is established using the simulating curves presented by Standing and Katz. The coefficients of the correlation are determined by fitting to the data of Standing and Katz Z-factor chart. The results of the two models are compared, the conclusion can be drawn that the error of LXF model is smaller than that of DAK model.

利用两种模型对不同拟对比温度和拟对比压力组合条件下的天然气偏差系数进行了拟合计算，与理论图版值的误差对比显示，在高温高压条件下LXF模型的拟合结果更优，特别是随着拟对比压力的增加，LXF模型的误差不断减小，因此，该模型更适用于高压和超高压条件下天然气偏差系数的工程计算。

Firstly, this paper researched the mechanism of tubing string vibration when natural gas flows in horizontal well tubing string. Secondly, established whole tubing string undamped and damped vibration system model according as reasonable assumption data of one horizontal well. Apply finite element analysis software to calculate tubing string natural characters, simple harmonic dynamic behavior of stable gas production and nonlinear dynamic behavior. Finally, this paper carried out the safety varied frequency of gas well and the method of vibration reduction.
