近几年,辽河冷家油田冷一原油集中处理站进站原油含水率不断升高,造成加热负荷不断增大,能耗持续增加,原油脱水效果大大降低,运行费用也大大增加等问题。通过对稠油脱水工艺技术的调查研究,采用预脱水工艺,解决了冷家油田高含水稠油脱水加热负荷过高的问题,节省了能耗,降低了运行费用。 In recent years, the Liaohe Cold Oilfield Cold First crude oil processing station into the standing crude oil moisture content continues to rise, resulting in heating load continues to increase, energy consumption continued to increase, greatly reducing the effect of crude oil dehydration, operating costs have also greatly increased and so on. Through the investigation of heavy oil dewatering technology, the pre-dewatering process is adopted to solve the problem of excessive heating and dehydration load of high water-containing heavy oil in Lengjia oilfield, saving energy consumption and reducing operating costs.
