抑制或防止气体水合物的生成一直是油气生产和运输部门关注的问题。针对上述问题,利用自行设计的实验设备,开展了多种钻井液处理剂对天然气水合物形成影响的实验研究;通过对实验数据分析得到了各实验组分的过冷度,并得出结论:在钻井过程中添加一定剂量的有机聚合物类处理剂可以抑制水合物生成,在实验条件下,抑制能力从强到弱分别为:PF-THTN、PAM、LV-CMC、XY-28、SD-102。 相似文献

The nonlinear dynamic behaviors of viscoelastic axially functionally graded material(AFG) pipes conveying pulsating internal flow are very complex. And the dynamic behavior will induce the failure of the pipes, and research of vibration and stability of pipes becomes a major concern. Considering that the elastic modulus, density, and coefficient of viscoelastic damping of the pipe material vary along the axial direction, the transverse vibration equation of the viscoelastic AFG pipe conveying pu... 相似文献
