双河油田是泌阳凹陷较早投入开发的百万吨级油田,也是我国高效开发的陆上油田之一,现已进入特高含水产量递减采油阶段。在其13年的稳产过程中,以地质特征认识为前提,以井网完善、注采结构调整为手段,最大限度地发挥油层潜力,始终保持油田以较高的采油速度生产(2.0%以上),取得较好的开发效果和经济效益。通过对双河油田高速高效开发模式解剖,形成一套行之有效的整装油田开发经验和模式,可为其它同类型油田的高效开发提供借鉴。

Shuanghe oilfield is not only a million-ton scale oilfield which has been earlier put into production in the Biyang Depression but also one of high-effectively developed onshore oilfields in China. Now it has been sliding into an oil-production decline stage with super-high water-cut. During 13-years stable production period, Shuanghe oilfield has been achieved better development effects and economic benefits through going on the premise of understanding geological characteristics and taking a measure of well pattern consummation and flood pattern modification in order to make the most use of sand capacity and keep producing in high speed (more than 2.0%) and high effectiveness from beginning to end. This article analyzes the mode of high-speed and high-effective development of Shuanghe oilfield and summarizes a set of effective development experiences for uncompartmentalized oilfields in order to use for reference to other similar types of oilfield development.
