Optimum flowing pressure will bring maximum productivity of the oil Wells in the low permeability oilfields.
在合理流压下，低渗透油田油井产能可得到最有效发挥。
The fluid flowing boundary extends outwards continuously is the feature of pressure propagation with low velocity Non Darcy percolation.
流体流动边界不断向外扩展是低速非达西渗流压力波传播的特点。
There is difficulty to confirm the bottom-hole pressure accurately and low accuracy and reliability when this kind well explained by using well testing model of flowing well.
对这类井，若采用自喷井建立起来的数学模型进行解释时，难以准确地确定关井时刻的井底压力，试井解释率低，可靠性差。
