Abstract

Abstract:

Deep-water oil and gas transmission tube is an important facility in deep-water oil and gas field development projects. Accurate simulation of the dynamic process of gas permeation and condensation is one of the key technologies for safe and reliable tube design. Taking the deep-water tube of an offshore oil field in China as the research object, the permeability law of complex gases CH₄, CO₂, H₂S and gas phase water inside the deep-water oil and gas conveying tube was studied. Considering the different factors affecting the permeability of the flexible pipe, such as polymer sealing material, thickness, gas pressure, gas temperature, flow rate, tube interface structure, etc., the hose geometry model was divided into three spaces: tube fluid, pipe structure and annulus, and the multi-phase flow heat and mass transfer coupling calculation model of composite flexible tube was established. Laboratory scale material and sample tube experiments, prototype pipeline tests and platform field tests were carried out, in which the maximum error between model results and sample tube experiments was 7%, and the maximum error between prototype pipeline tests was 12.3%. The calculation model was consistent with the trend law of field operation results, providing technical support for the design of deep-water pipeline and the safe operation management of tubes.

Key words: deep-water tube, mult-phase flow heat and mass transfer coupling, permeation model

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。
