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。
The reservoir in Upper Palaeozoic of North Ordos Basin is compacted continental hidden reservoir characterized by lower porosity, lower permeability, lower pressure and multilayer overlapping.
鄂尔多斯盆地北部上古生界是陆相致密的隐蔽性气藏，具有低孔、低渗、低压、多层叠置的特点。
Having entered into the later period of high water cut in Gaotaizi reservoir, pressure difference between blocks is bigger, oil-to-water-well ratio is higher and pattern density is lower.
针对萨中高台子油层进入高含水后期，区块间压力差异较大，油水井数比偏高，井网密度低，计算了合理注采井数比及井网密度，评价了目前的注采压力系统。
