在计算压降的经验公式与理论公式的基础上,提出了基于混输管道数据库水力插值计算方法,采用SQLServer2008与visualC.NET软件建立油气水混输管道数据库并开发数据库管理平台,实现水力插值计算,以环道试验数据作为基础数据对插值预测法计算结果进行验证,并与PIPEPHASE软件及OLGA软件计算结果进行对比分析,结果表明:插值预测法计算误差在PIPEPHASE软件及OLGA软件最小误差基础上降低30%以上.
Based on the empirical formula and theoretical formula for calculating pressure drop, a hydraulic interpolation calculation method based on hybrid pipeline database is proposed. The database of oil-gas-water mixed pipeline is established by SQLServer2008 and visualC.NET software, and the database management platform is developed to realize hydraulic interpolation calculation , The results of interpolation prediction method are verified by using the data of the loop test as the basic data, and compared with the results of PIPEPHASE software and OLGA software. The results show that the interpolation error of interpolation prediction method is reduced on the basis of the minimum error of PIPEPHASE software and OLGA software More than 30%.
