【摘要】 介绍力学所建造根据实际工艺情况设计的油中除砂技术的模拟试验设备。它是采用泵站和引射器按一定油水配比混合油、水、砂,进入两级离心式分离器逐级分离, 在出口处设置残砂捕集器,把分离器溢口流出的小砂粒收集起来,从入口处砂的称量结果, 和分离器、捕砂器收集到的砂量,可以得到分离器的效率和除砂粒径范围。经过多次不同比例的低黏度油、水、80目以下粒径的砂分离实验,实验结果表明:分离效率在95％以上, 为下一步在陆上油田和海上石油平台的应用打下坚实的基础。在此基础上,继续探索稠油除砂和分离效率更高的分离器。更多还原

【Abstract】 In this paper the simulated experimental instrument of oil desanding technique is introduced, which was constructed in Institute of Mechanics and was close to practical situations. Its operational principle is mixing oil, water and sand according to certain oil-water proportions using pumps and an injector, then separating step by step in two-stage centrifugal separator; next installing outlet catcher to collect small sand particles which pass the outflow lip, finally the separating efficiency and the desanding range of particle size can be obtained by analyzing the measurement results of sand quantities at inlet side, separator and catcher. The instrument has been built and operates well, and good separating results have been obtained from the preliminary experimental data for a certain range of sand particle size.更多还原
