摘　　要：油田进入高含水期开发之后,稳产的基础是挖掘剩余油潜力,不断增加剩余可采储量。而对剩余油空间分布的描述及其定量化,是研究工作的重点和难点。数值模拟作为一项成熟的技术,在油田开发各阶段发挥了重要作用,但如何提高数值模拟的精度和量化剩余油是制约数值模拟技术发展的瓶颈。在此结合精细油藏描述,引入分流动单元模拟技术,大大提高了模拟精度,缩短了拟合时间,同时,利用一体化平台,探索出了一种剩余油空间分布量化技术方法。研究成果积极应用于吐哈盆地鄯善油田东二区开发调整中,取得了良好效果。Stable production is based on excavation for remaining oil potential and continuous increase of remaining recoverable reserves after oilfield turns into the high water - cut production period. Emphasis and difficulty for study work are the description and quantization of space distribution of remaining oil. Numerical simulation plays an important role at various developing stages for the oilfield as a mature technique, but how to improve the precision of numerical simulation and quantify remaining oil is the bottle - neck problem which prevents numerical simulation technique from advance. Combining fine reservoir description and introducing seperate flow unit modeling technique can improve modeling precision at a large extent and shorten matching time. Meanwhile using integration platform explores a technique quantifying space distribution of remaining oil. The study result is actively applied to the development adjustment of the block east No. 2 area in Shanshan oilfield in Tuha basin, with good effect.
