Research progress on methane hydrate formation in oil and water emulsion
摘要
Abstract
In the process of oil and gas extraction and transportation,the hydrate which formed by high pressure and low temperature conditions,affected the normal operation of the pipeline,and might cause safety accidents. With the development of hydrate inhibition and anti-blocking technology,the formation of methane hydrate in the emulsion system has become the research focus. To grasp the formation rule of methane hydrate in oil-water emulsion system,and understand the factors that affect the formation of methane hydrate,and provide a paradigm shift to suppress the formation of hydrate in the high-pressure oil and submarine pipelines,this paper summaried the mechanism of methane hydrate formation in the emulsion system and the model of hydrate growth shell. The concept of the "memory effect" of water was introduced. The effects of emulsion water content,particle size,stirring rate, temperature and pressure conditions,oil phase,additives and many other factors on the formation of hydrate were analyzed. Finally,it is pointed out that the formation of hydrate is affected by various factors which are interrelated and can not be analyzed separately,and that the multiphase flow of oil-wateremulsion also makes the problems much more complicated. At present,the influencing factors and principle of methane hydrate in emulsion system are not fully understood and further studies are needed.关键词
