Therefore, established a finite element Stable response model of a horizontal whole string and carried out t the safety varied frequency of gas well after researched the natural seriously transversal vibration and compressional vibration frequency range of tubing string with packer and packerless, so that it make the tubing string to avert the covibration frequency range of natural gas excited.
本文认为以某井高产量稳产时，天然气对油管柱的外激励为简谐激振，因此研究中建立某水平井全井段油管柱稳态响应的有限元力学模型，并获得了在无封隔器和有封隔器情况下的油管柱发生严重横振和纵振的频率范围，提出了天然气安全调节频率范围，使油管柱避开可能引起严重破坏的天然气激励频率区域。

Low-frequency covibration experiments of four kinds of fluid-saturated feldspar sandstones which have different viscosity coefficients respectively were conducted so as to know how fluid viscosity coefficient influences attenuation, modulus and velocity dispersion in fluid-saturated sandstone.
为了探讨孔隙流体的黏滞系数对饱和砂岩的衰减、模量和速度色散的影响，本文进行了四种不同黏滞系数的饱和长石砂岩的低频共振实验，结果发现在0.01～10Hz频带范围内，无论是衰减温度话还是衰减频率谱，都显示出衰减随黏滞系数的增大成良好的线性增长关系，黏滞系数越大楼量越大；同时还具有明显的模量与速度色激，而且随着黏滞系数的增大，模量与速度色权有增强的趋势。
