摘　　要：厄瓜多尔D-F油田是一个开发近四十年的老油田,目前油田开发已进入"双高"阶段,稳产形势十分严峻。同时研究区面临构造精度低、油水关系复杂、剩余油分布零散、注采井网不完善等诸多问题。通过重构地下认识体系,开展精细地质研究,摸清剩余油分布规律,并采用天然能量合理利用技术及注水优化技术,有效地减缓了产量递减和含水上升速度,为同类型油藏的开发提供了一定的借鉴。Ecuador D-F Oilfield is an old oil field which has been developed for nearly forty years. The oil field＇ s development has entered a stage of ＂double high＂ with grim stable production. At the same time, the study area has the problems such as low accuracy of construction, complex oil-water relationship, scattered distribution of remaining oil, imperfect injection-production pattern and so on. By reconstructing underground recognition system, carrying out fine geology research, finding out re- maining oil distribution law, using rational utilization of natural energy technology and optimization of water injection technology, we have effectively slowed down the production decline and water cut rising rate. All of the above hopefully will offer some reference for the development of similar reservoirs.
