美国老油气区“挖潜”的有效措施

The Effetive Measures of Tap Production Potential in Old Oil and Gas Regions in the United States

美国老油气区的“挖潜”富有成效。据统计，1978～1991年美国老油气田的储量增长量占全美总探明储量增长量的90％以上。老油气区是过去和将来几十年间美国油气增储上产的主要领域。美国老油气区“挖潜”一是通过对现有的各种资料进行再分析，获得地质认识上的突破，从而打开勘探工作新局面；二是靠技术手段的改进，勘探开发难度大的复杂油气藏；三是靠多学科项目管理，解决实际生产中的重大难题；四是大力发展提高采收率技术。文中结合几个老油气区增储上产的实例，介绍了美国老油气区“挖潜”的几种有效措施，同时对老区“挖潜”的经济效益进行了分析。

The tap production potential in the old oil and gas regions in the United States is very effective. By statistics,the reserve increment in the old oil and gas regions is over 90% of proven reserve increment during 1978~1991.The old oil and gas regions are the main field increasing reserve and production during the past decade and the next decades in the United States.The tap production potential in the old oil and gas regions depened on the breakthrough of geology knowledge,improvement on technology,strengthening project management and enhanced oil recovery method.This paper presents the effective measures of tap production potential in the oil and gas regions in the United States, combining with the examples of increasing reserve and production in the old oil and gas regions,and analysizes the economic effect of tap production potential.
