立管高度对严重段塞流的影响分析

摘要

With the increase of oil demand in China, exploitation of offshore oil and gas is becoming more and more important; it will become the main growth point of our country’s oil industry. In the exploitation process of offshore oil and gas, the problem of severe slugging in the riser system is often encountered, which brings serious challenge for the flow assurance. In this paper, through changing the height of the riser pipeline, effect of the riser height on the severe slugging was deeply analyzed, and the distribution law of characteristic parameters of the slugging under different riser height was obtained, and the mechanism of producing the severe slugging was analyzed. The research results can provide the basis for design of the riser pipeline in the future exploitation process of offshore oil and gas.%随着我国对石油需求量的增加，海上油气开发越来越受到重视，并且将成为我国石油工业未来的主要增长点。在海上油气田开采过程中，经常会遇到立管系统严重段塞流问题，给安全流动保障带来严峻挑战。通过改变海洋立管高度，对立管高度对严重段塞流的影响进行了深入分析，得到了不同立管高度情况下，严重段塞流的特征参数分布规律，并分析了产生机理。研究结果对于未来海洋石油开采中的立管设计可以提供一定依据。
