油气藏流体水合物浆输送技术研究进展

在油气藏流体中加入新型抑制剂,使其中的天然气生成水合物,并悬浮在油气藏流体中,流体以水合物浆的形式进行输送,可以解决管道的流动保障问题。水合物颗粒引起流体特性的变化,给管道输送带来了复杂性。从水合物浆的相平衡、抑制剂、流动特性、堵塞预测及解堵四个方面,对国内外油气藏流体水合物浆输送技术的研究进展作了归纳。介绍了国内外主要研究机构在研究中使用的方法、设备,以及取得的成果,提出了国内在水合物浆输送研究方面将来的努力方向。

State-of-the-art on Transportation technology of reservoir fluid hydrate slurry

Novel hydrate inhibitors can be added to unprocessed reservoir fluid to form and suspend gas hydrate in it,so unprocessed reservoir fluid is transported as hydrate slurry,which can solve flow assurance problems.Gas hydrate particles alter the fluid flow characteristic,and make pipeline transportation more complex.The research on transportation technology of reservoir fluid hydrate slurry home and abroad was summed up in phase equilibrium of hydrate slurry,inhibitors,flow characteristic,and plug prediction.E...
