摘要
了解注水波及系数及油层的水淹状况是注水开发油田动态分析的一项重要内容。利用高精度电子压力计测取油水井压力恢复 (压降 )试井曲线 ,可判断油水两相流动区域 ,确定油藏的渗流特征 ,监测地层流体的流动状态 ,确定地层参数 ,了解注水前缘及水淹区含油饱和度的变化 ,从而为注水开发研究和调整提供可靠的依据。
What knowing about water injection sweep efficiency and oil layer's water flooded condition is an important content for dynamically analyzing devel opment oilfield by water injection.Utilizing build up pressure testing curves ( o r down pressure curves) measured by electronic gauge with high accuracy,it can j udge the reservoir's percolation features in the flowing area with oil and water two phase,monitor flowing conditions of formation fluid,determine formation par ameters and acknowledge the change of oil saturation at water injection front an d in water flooded area,thus provides a liable basis for studying of water injec tion development and its adjustment.
