Johnson screen

1, the higher the hole rate of the water pipe is more suitable for the construction of high efficiency water, oil, gas wells, mass transfer equipment.
2, low operating costs Low opening rate of the water pipe, oil sand control pipe is more conducive to the infiltration of groundwater, plenty of water to reduce the water level to reduce, thereby reducing energy consumption.
3, can reduce the wear of the pump Under the same conditions, the higher the hole rate makes the groundwater into the sand pipe when the speed of infiltration into other filter device when the speed is much slower, so as to avoid the sand in the larger water Press down into the sand control tube, reducing the pump wear.
4, to extend the life of the wells In contrast, the groundwater into the open hole filter pipe more easily, low water flow, to extend the life of wells.
5, Johnson mine screen in the chemical filler widely used, high efficiency distillation.
