摘要
通过室内物理模拟实验对密闭取心过程中由于降压脱气导致含水饱和度变化进行了测定和分析 ,获得了砂岩油藏不同水淹状况下降压脱气前与降压脱气后含水饱和度的变化关系 ,以及不同气油比下降压脱气对含水饱和度损失的影响 .建立了一套操作简单、实用性强的含水饱和度校正流程 .给出了针对华北油田京 2
The change of the water saturation of cores caused by the degasification in sealing core drilling is measured through laboratory simulation experiment. The relationships between pre-degassing and post-degassing water saturation of sandstone reservoir under different waterflooded situation and the effect of different gas/oil ratios on the loss of the water saturation of cores are presented. A flowsheet for the correction of water saturation is proposed. The correction formula of the water saturation of the cores from the major reservoir of Jing 271 well in Huabei Oilfield is presented.
