Review of hydrate plugging mechanisms in oil and gas transport pipelines
摘要
Abstract
Although many experimental studies were conducted on oil-gas transportation pipeline hydrate plugging mechanisms worldwide,there has always been a lack of systematic summary. According to the difference in experimental conditions,oil-gas transportation systems were firstly divided into oil-dominated systems,water-dominated systems(water systems and water-continuous systems),gas-dominated systems and partially-dispersed systems. Analyses show that there are many pipeline hydrate plugging mechanisms,including hydrate agglomeration and deposition,hydrate jamming and the separation of oil and water. For oil-dominated systems,hydrate agglomeration/jamming and hydrate deposition(film growth,wall adhesion and bedding)are the main plugging mechanisms. For water systems,hydrate particle bedding is the dominant plugging mechanism. For gas-dominated systems,hydrate agglomeration and stenosis caused by hydrate jamming are the main plugging mechanism. As for the main plugging mechanisms in water-continuous systems and partially-dispersed systems,there is no definite conclusion can be drawn and much work is still needed. Quantitative researches on droplet size distribution in annular flow,oil-water dispersion state,emulsion stability and non-emulsified free water are the focuses of hydrate plugging mechanism research in the future.关键词
