油田加热炉清洁替代技术的研究与应用

Research and application of clean alternative technology for oilfield heating furnace

随着社会对绿色环保发展的重视,油田生产采用加热炉燃烧一次化石能源的供热模式已逐渐不能适应低碳发展需求,为了有效减少油田燃料消耗,减少碳排放,依托油田站场采出水、伴生气等资源,开展了油田加热炉清洁替代技术的研究与应用,研究提出三种不同技术路线的热泵工艺技术,将低品位采出水余热及大气热能转化为可供油田站场生产使用的高品位热能,先导试验成功替代了加热炉,较传统供热技术能效比均大于1,有效降低能源消耗与碳排放,并明确了选择热泵技术路线需考虑的主要因素,累计推广应用11座站场,规模效益显著,有效促进油田绿色低碳发展。

With the attention of the society to the development of green environmental protection,the heating mode of heating furnace burning fossil energy in oilfield production has gradually been unable to meet the needs of low carbon development.In order to effectively reduce the consumption of oilfield fuel and reduce carbon emissions,based on the resources of oilfield station produced water and associated gas,the research and application of clean alternative technology of oilfield heating furnace are carried out.Three heat pump technologies with different technical routes are studied and put forward.The low grade produced water heat and atmospheric heat are transformed into high grade heat energy for oilfield station production.The pilot test successfully replaces the heating furnace,and the energy efficiency ratio is greater than one compared with conventional heating technologies.The energy consumption and carbon emissions are effectively reduced,and the main factors that need to be considered in the selection of heat pump technology route are clarified.A total of eleven stations have been promoted and applied withremarkable scale benefits,effectively promoting the green and low carbon development of oilfields.
