【摘要】 通过现有的构造、储层、测井等静态资料和研究成果,建立了马宁油田长212油藏地质模型。历史生产数据拟合表明研究区仍处于天然能量开发阶段,为提高产油增长率,需尽快投入注水开发。为了使水驱储量最大化、解决注水后的含水快速上升等问题,运用模拟技术分别对井网密度、注采井网以及注采比方面进行优化设计。通过数值模拟得出以下结论:(1)井网密度确定为17.8井/平方千米;(2)在地质条件基本一致的情况下,井网密度取17.8井/平方千米时,反七点面积注水方式效果最好;(3)模拟计算15年,确定本研究区合理注采比为1.0。通过数值模拟、历史拟合、注水方式优选以及开发指标预测,为该油藏的科学高效开发提供了依据。更多还原

【Abstract】 Through the geological structure, reservoir, well logging and other static information and research results,established the reservoir geological model of Chang2 1 2 Maning oil-field.According to historical production data fitting shows that the study area is still in the development phase of natural energy and is better to operate waterflooding right now. In order to maximize waterflood reserves and control the problem of the rapid water increase during flooding.Well spacing density, injection patterns and injection-production ratio is optimized by simulation.Conclusions are as follows:(1)best well spacing density 17.8 wells/km 2 ; (2)in the case of geological conditions are basically the same, well spacing density taken 17.8 wells/km 2 , and the best pattern is Fan Qidian(;3)according to simulation of 15 years, the reasonable injection-production ratio is1.0.Through numerical simulation, history matching,waterflooding optimization as well as the forecast of development indicators, which provides a basis for this reservoir of scientific and efficient development.更多还原
