海底油气管道流动保障技术研究进展

Research Progress in Flow Assurance Technology for Submarine Oil & Gas Pipelines

面对深海低温高压的特殊环境,在深海油气田的不断开发过程中,流动保障成为了深海油气资源输送过程中亟待解决的问题之一.在深海油气田的流动保障中所要解决的主要问题是流动堵塞,即水合物、蜡、水垢、沥青质等固相的沉积.主要从蜡沉积、水合物生成以及二者之间的相互影响等三个方面进行论述,介绍了国内外深海管道流动保障技术研究的最新进展,为我国在深海油气田流动保障技术的进一步研究提供了参考.

Faced with the special environment of deep-sea low temperature and high pressure, in the process of continuous development of deep-sea oil and gas fields, flow assurance has become one of the urgent problems to be solved in the process of deep-sea oil & gas resources transportation. The main problem that need be solved in the flow assurance of deep-sea oil & gas fields is the flow blockage, i.e. the deposition of solid phases such as hydrate, wax,scale and asphaltene. In this paper, wax deposition, hydrate formation and the interaction between them were mainly discussed. The latest development of deep-sea pipeline flow assurance technology at home and abroad was introduced,which could provide some reference for the further study of deep-sea oil and gas field flow assurance technology in China.
