摘要:
深水油气输送软管是深水油气田开发工程重要的设施,准确模拟气体渗透冷凝的动态过程是关乎软管设计是否安全可靠的关键技术之一。以我国海上某油田深水软管为研究对象,开展深水油气输送软管内部复杂气体CH4、CO2、H2S和气相水等渗透规律研究,考虑高分子聚合物密封材料、厚度、气体压力、温度、流速、软管界面结构形式等不同影响软管渗透性的因素,将软管几何模型划分为管内流体、管道结构和环空三个空间,建立复合柔性软管多相流动传热传质耦合计算模型,并进行了实验室规模的材料和样管实验,原型管道试验以及平台现场测试,其中模型结果与样管实验最大误差为7%,与原型管道试验结果最大误差为12.3%,计算模型与现场运行结果趋势规律一致,很好地为深水软管设计以及软管安全运行管理提供技术支持。
