青东5海油陆采开发模式生产,原油在生产和外输过程中需要消耗较大的燃料进行掺水和升温进行原油降粘。在满足管输体积条件和原油乳化反相条件下对原油掺水量进行分析,确定了不同油井液量下的外输掺水量函数F(X),结合现场外输温度确定了最佳外输温度为43℃。将分析结论运用于现场生产后,掺水加热耗燃料油由之前的15吨/天降低到8.8吨/天,节能效果明显。 Qinghai 5 offshore oil exploration and development mode of production, crude oil production and transportation in the process need to consume larger fuels for water and heating for crude oil viscosity reduction. The water content of crude oil was analyzed under the conditions of the volume of tube transportation and the phase inversion of crude oil emulsified. The function F (X) of water transfer was determined under different oil well volume. The optimum temperature 43 ° C. After applying the conclusion of the analysis to the on-site production, the fuel oil with water heating and heating energy was reduced from the previous 15 tons / day to 8.8 tons / day with obvious energy-saving effect.
