摘　　要：随着油气勘探开发的不断发展,井深逐步加大,压力、温度也逐步升高,伴随着蒸汽吞吐、蒸汽驱特别是火烧油层等技术的应用,开采层的温度、压力可能达到水的超临界点。由于超临界水有很多性质,如具有极强的氧化能力,可以溶解很多物质(比如油),能够缓慢地溶解腐蚀几乎所有金属,具有超级催化作用,这些性质对油藏的开发有着极大的影响。超临界多元流体模拟实验系统可以在室内条件下,通过模拟实际深井条件,进行超临界多元流体对原油采收的影响的探索;进行超临界多元流体对油、套管及地层的腐蚀影响的研究。With the continuous development of oil and gas exploration and development,the depth of wells gradually increases,and the pressure and temperature also gradually rise.With the application of technologies such as steam injection and steam flooding,especially the burning of oil layers,the temperature and pressure of the production layer may reach the supercritical point of water.Due to the many properties of supercritical water,such as its strong oxidation ability,the ability to dissolve many substances(such as oil),the ability to slowly dissolve and corrode almost all metals,and its super catalytic effect,these properties have a great impact on the development of oil reservoirs.The supercritical multi-component fluid simulation experimental system can explore the impact of supercritical multicomponent fluid on crude oil recovery under indoor conditions by simulating actual deep well conditions;Conduct research on the corrosion effects of supercritical multicomponent fluids on oil,casing,and formation.
