Volcanic gas reservoirs of low permeability in the carboniferous of a basin are characterized by deep burial depth, complex genesis, many types, wide distribution and non-evident expressions in three-porosity log curves, as well as the variedvalues of density and compression wave of main four volcanic gas reservoirs (such as the basalt, andesite, dacite and rhyolite). So a number of effective methods based on three porosity log data cannot work in identifying the volcanic gas reservoirs of the carboniferous of the basin.

石炭系火山岩的低渗透气藏具有的埋藏深、成因复杂、类型多、分布广、三孔隙度曲线响应特征不明显等特点，并且主要的四种火山岩气藏：玄武岩、安山岩、英安岩、流纹岩的密度和纵波时差测井值差别较大，因此使基于三孔隙度测井资料的一系列识别气层的有效方法在该盆地石炭系火山岩气层的识别中无明显效果。

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.
