油田产出水型地热资源开发研究

Study on the Oilfield Produced Water Geothermal Resource Development

油田产出水型地热资源是油区地热开发利用中很容易被忽略或浪费的一种特殊类型的沉积盆地型地热资源。在详细分析了其形成机理的基础上,首次提出了油田产出水型地热资源的概念。从资源潜力、开发成本、市场前景三个方面论述了其特征,探讨了其在油田掺水集输、伴热集输及驱替原油三个方面直接开发利用技术。提出了"用热不用水"的间接利用理念,探讨了采用热泵技术开发利用油田产出水型地热资源服务于油田生产和周边居民的可行性,为油田产出型地热资源深入利用奠定了坚实的基础。

Oilfield produced water geothermal resource that is very easy overlooked or wasted in the exploitation of oilfield geothermal resources is a special form of sedimentary basin geothermal resource.Based on detailed analysis of oilfield produced water geothermal resource formation mechanism,its concept is firstly proposed.Oilfield produces water geothermal resource characteristics are expounded from three aspects of resource potential,development cost and market prospect,proposes the idea of using heat and adverse water,discussed the feasibility of development water geothermal resource to service in oil production and circumjacent dweller by using heat pump technology and lays a solid foundation for its in-depth exploitation.
