稠油的生产主要以热采为主,热采就是用热注锅炉(一般23t/h)将软化后的净水加热成高温、高压蒸汽,通过管线注入到油层,提高稠油的温度,增加流动性,起到驱油的作用。以辽河油田为例,去年稠油产量约860×104t/a,而热采稠油约占80%以上,每年的注汽量约500×104t/a,消耗的燃料油约100×104t/a,价值十几亿元,从稠油操作成本构成分析,燃料费约占30～40%。因此,降低稠油操作成本首先要降低注汽祸炉的燃料费用,而降低燃料费用必
Heavy oil production is mainly thermal recovery, thermal recovery is the use of hot injection boiler (usually 23t / h) will be softened water heated to high temperature and high pressure steam, injected into the reservoir through the pipeline to increase the temperature of heavy oil, increase Liquidity, play a role in oil displacement. Taking Liaohe Oilfield as an example, last year’s heavy oil output was about 860 × 104t / a, while thermal recovery heavy oil accounted for more than 80%, the annual steam injection amount was about 500 × 104t / a, and the consumed fuel oil was about 100 × 104t / a , Worth billions of dollars, from the operation cost of heavy oil composition analysis, fuel costs accounted for about 30 ~ 40%. Therefore, to reduce the operating cost of heavy oil, we must first reduce the fuel cost of the steam injection furnace and reduce the fuel cost
