【摘要】 本文介绍中科院力学所在液固分离技术方面开展的研究工作。通过有关文献总结、专利调研和国内现场考察,在几种液固分离技术中选用离心方法,建设了相应的模拟试验设备。在实验中,进行了纯油-砂分离、不同比例的油-水-砂分离实验,总结了几个方面的影响因素,选择了一种合理的除砂方法,在胜利油田、华北油田进行了工业现场应用实验,取得了良好结果。十五期间,从发展海上油气混输特殊工艺要求出发,作为混相增压技术的配套技术,采用离心分离除砂技术,最大限度地减少对多相混输泵的伤害,保证混输工艺的可靠实现。更多还原

【Abstract】 The research work on the developments in solid-liquid separation tests is presented in this paper. Based on papers’ review and industry survey, we selected hydrocy-clone for desanding, and then the corresponding device was set up in Institute of Mechanics. From the simulation experiments, a rational desanding method has been selected and applied in some oil field, such as Sheng-Li and Hua-Bei oil field. During the period of The 10th Five-year of CAS’ , it’s an important technology to transport oil-gas flow by pipe line. As the sand is separated from oil-gas multiphase flow, it can prevent the multiphase pump formbeing damaged, and keeps the pumps working order- ly.更多还原
