Abstract: A number of fractured buried hill oil and gas reservoirs have been discovered and brought under development in Huabei region since the 1970s. This paper makes briefings about the present reserves, geological characteristics and development situation of buried hill reservoirs as well as the bottlenecks of high water cut and low production in the later development stage of those reservoirs. To improve operation of oil reservoirs and economic performance, it is proposed that oil companies should timely turn to the development pattern that is focused on geothermal exploitation instead of oil production, establishing a new-type industry for oil and gas development in common with geothermal resources. As for the stage that is focused on geothermal development, it is proposed to explore the new mechanisms for business management and utilization, promote development on a large scale, and enhance dynamic management

Key words: buried hill oil reservoirs, oilfield development, geothermal resources, sustainable development

摘要： 20世纪70年代以来,华北地区先后发现并开发了多个裂缝性潜山油气藏,介绍了潜山油藏储量现状、地质特点及开发现状,面临着油藏开发进入低速缓慢递减阶段出现的高含水低产油难题。为了改善油藏经营状况,提高经济效益,建议油公司适时转入地热开发利用为主、采油为副的发展模式上来,创建我国新型油气与地热资源共同开发的产业。针对地热开发为主阶段,建议积极探索经营管理及利用新机制、规模化发展、加强动态管理等措施。
