用核供热堆开发高凝油田的经济评价

Economic study of NHR application on high pour point oil field

为了进一步拓宽核供热堆应用的领域，降低油田采油成本，在对大庆萨北过渡带１６．９ｋｍ２的高凝油藏开展历史拟合、热水驱替的开发方案和实施热流体循环工艺研究的基础上，对配置不同方案的核供热堆和燃油锅炉提供热源开发油藏进行了针对性研究，结果表明，利用核供热堆提供热源来进行高凝油开发的供热成本大约是燃油炉的三分之一，按２０ａ的生产期计算，净生产原油和净盈利大约是燃油炉方案的４倍。从经济性和运行可靠性来讲。

In order to extent the application of NHR (nuclear heating reactor) and cut down the oil production costs, the authors designed different heating disposition by NHR and boiler heating stations in high pour point oil reservoir, total 16.9 km 2, in Daqing oil field. This work was based on the study of history matching, water flood planning and hot water circulation for the reservoir. The analyzing results show that, the convert heating cost of NHR is a third of boiler's and the net oil production of NHR is 4 times more than the latter. Considering economization and reliability, authors suggest to adopt the scheme of two NHR with one boiler heating station.
