So the expansion against lower pressure draws less heat from the hot reservoir right.
所以压强较低时的膨胀,从高温热源吸收的热量更少。
The lower the permeability and the smaller the pore-throat radius as well as the lower the reservoir pressure, the easier the formation of water locking damage, and it is difficult to be removed.
渗透率越低,孔喉半径越小,油层压力越低,越容易产生水锁损害,且越难以解除其损害。
The switch can be opened or closed when the well pressure is lower or higher than the reservoir pressure respectively.
此开关能在井内压力小于油层压力时开启,大于油层压力时关闭。
