When oil enters the hole of water-wet sandstone driven by pressure difference, oil migrates following a line of less resistance because of the migration force of oil is bigger than that of water.
油在压差驱动下注入亲水砂岩孔隙的过程中，油的运移阻力比水大，因而，油往往沿阻力较低的有限通道运移。

Supervisor Road: including oil suction line, pressureoil pipeline and oil return line, used to achieve the transfer of pressure energy.
主管路：包括吸油管路，压油管路和回油管路，用来实现压力能的传递。

So much oil and natural gas have come forth that the pressure is equalizing and the risk thus down somewhat on that long fissure line we have spoken of before.
