摘要:
大庆油田北三区位于大庆长垣萨尔图油田纯油区内。该区块特高含水期剩余油高度分散,挖潜难度大,各层系间含水差异越来越小,注水低效无效循环越来越严重,过渡带开发效果有待提高。虽然厚油层综合含水高,但剩余油储量大,为下一步的重点挖潜目标,厚油层砂体中高弯曲分流河道砂体所占比重最大。针对高弯曲分流河道,以北三区西部SⅡ1+2b层为例,建立厚油层储层建筑结构(构型)的分布模式,研制储层建筑结构、三维建模及数值模拟的地质解剖、预测和建模数模技术,深化高弯曲分流河道砂体内部建筑结构和剩余油分布的认识,为开发动态分析、剩余油挖潜提供更准确的地质依据。
Abstract:
The Bei3 region is located in the pure oil district of Saertu,Daqing Oilfield.At present,the remaining oil at ultra high water-cut stage is highly decentralized in the block,so taping the potential is difficuly.The contrast of water cut becomes smaller and smaller between layer series,and the phenomenon of inefficient water injection and invalid cycle becomes worse and worse.So we need to enhance the development effect of transitional zone.Although the average water-cut of thick oil pay is high,the thick oil pay is taken as the next potential taping goal due to large remaining oil reserves.The highly crooked distributary channel sandbodies occupied the maximum proportion in the thick oil pay.Aiming at the highly crooked distributary channel sandbodies,taking SⅡ1+2b layer,in western Bei3 district as an example,the distribution pattern of reservoir configuration of the thick oil pay was established.It was studied on the distribution pattern of the reservoir configuration,the triaxial geology dissection and prediction of modeling and numerical simulation,and the modeling and numerical simulation technology.Through deepening the knowledge of internal structure model and the remaining oil distribution for the highly crooked distributary channel sandbodies,it can be provided a more accurate geology reference for analysis of developing performance and remaining oil development.
