二氧化碳水合物浆液在不同含水率下的流动特性
Flow Characteristics of Carbon Dioxide Hydrate Slurry under Different Water Content
摘要
Abstract
As the oil and gas industry strives to find better gas hydrate management methods,it is necessary to better understand the hydrate formation and plugging trend in multiphase flow.The high-pressure visual flow loop is used to study the formation of carbon dioxide gas hydrate and the properties of hydrate slurry under the flow conditions of complete dispersion and partial dispersion system.The results show that for the fully dispersed phase system with high water content,the contact area between gas molecules and water is larger,and hydrate can be fully generated,which has a great impact on the flow in the loop.For the two systems with different water content,because of the oil-water interface in high water content is damaged more violently,a large amount of hydrate is easier to block the loop.The oil-water interface in low water content can be supplemented after being damaged,so the risk of pipe plugging is low.关键词
