摘要 经历四十多年开发,大庆杏树油田主力油层已进入高含水后期。针对高含水后期调整挖潜的剩余油评价难题,利用水驱油实验资料、密闭取心与井壁取心对比分析实验资料、试油及投产资料,系统总结了随含水上升,地化色谱和荧光图像特征的变化规律,揭示了水淹层录井响应机理,建立了以地化色谱、荧光显微图像分析等新技术为手段的水淹层录井评价方法。该评价方法可直观、准确地评价剩余油,进而确定剩余油挖潜部位,在调整井中应用见到了明显的效果,成为在高含水主力油层深化挖潜和薄差层有效动用过程中,剩余油评价和射孔选层的关键技术之一,对于科学合理开发调整、提高油田开发效果具有重要意义。 After over 40 years oil and gas development, The main oil layer of Xingshugang oilfield becomes the situation of entering high water cut. For solving the remaining oil adjustment and tapping potential problem of high water cut, we study variety of water content and summarize logging response mechanism of water cut through geo--chemical pyrolysis data , saturated hydrocarbon gas chromatography data and fluorescence microscopic image data. We establish an effective water- flooded zone logging evaluation method by using data of oil--water displacement experiment, sealed coring, sidewall coring, oil testing and production data. It can accurately evaluate the distribution of remaining oil of the adjustment wells, and becomes one of key technologies to tap potential remaining oil layers and optimum perforation zones. It is important for developing and improving the oil production and recovery of Xingshugang Oilfield.
