中文摘要
随着油气资源开采趋向输送条件恶劣的深海领域,蜡与水合物共存时的协同作用严重影响深海油气混输管道运行安全。目前,蜡-水合物协同体系的形成、流动、沉积及堵管机制尚不明确,这掣肘着深海流动保障技术的实施与发展。为此,本项目拟借助微观力学测量装置及可视化流变仪等实验技术手段,开展油气混输管道内蜡-水合物协同体系水合物相界面特征、微观颗粒黏聚及流变特性的研究。以期阐明协同体系中蜡晶作用下的水合物界面生长特性及相界面特征,查明协同体系微观颗粒间黏聚力演变规律及耦合聚并机理,建立考虑水合物相界面特征的黏聚力理论模型,厘清协同体系颗粒行为(聚并、剪切破碎及重组等)、聚并状态及结构特征的同一性、差异性及依时性,揭示其对协同体系流变特性的影响机理,构建考虑聚并状态及结构特征的协同体系表观黏度演变预测模型,进一步认识物质微观结构对其宏观物理特性的作用,并为深水油气开采及混输管道运行安全提供理论依据与技术支持。
英文摘要
With the developing of oil and gas production towards the deep sea with the serious transmission environment, multiphase gathering lines are prone to be affected by the wax-hydrate synergistic system. The formation, flow, deposition and plugging mechanisms of the synergistic system still remain a big knowledge gap, which severely hinders the implementation and development of deep-water flow assurance technology. Therefore, the interface characteristics of hydrate phase, cohesive mechanism of microscopic particles and rheological characteristics of flow system will be studied with the assistance of experimental technologies including micromechanical force measurement apparatus and visualized rheometer. The morphology characteristics of interfacial hydrate growth in synergistic system will be elaborated, as well as the function mechanism of wax crystals on the irregularity and thickness of hydrate shell. The evolutionary mechanism of the cohesive force between microscopic particles involving hydrates and water droplets as well as the agglomeration mechanism will be reveled, and a theoretical model of the cohesive force between microscopic particles will be presented. The influencing mechanism of microscopic particle behaviors (agglomeration, break up and reorganization, etc.), agglomeration characteristics (identity, difference and time-dependence, etc.) and structure characteristics on the rheological characteristics of synergistic system will be explained. Meanwhile, a comprehensive model considering the agglomeration and structure characteristics will be established to predict the apparent viscosity of synergistic system during the whole evolutionary process. This study will contribute to understanding the effect of microscopic structure of mater on its macroscopic physical characteristics, and provide theoretical references and technological supports for the safety of multiphase transportation pipelines and the safety of deep water production.
