water-free well

基本解释

The viscosity reducing rate will reach over 99% or more when augmenting light oil mass of water-free heavy oil well, lower temperature will lead to better performance of viscosity decrease.
不含水稠油井的降粘率随掺稀质量的提高而增大，其值可达99%以上，温度越低降粘效果越好。
Inadequate submergence can result in pre-rotation of the water in the wet-well, resulting in the formation of strong free-surface air core vortices and the entrance of air into the pump suction inlet.
潜水不恰当可能导致湿井内的水预旋转，导致形成强烈的自由表面空气中心漩涡，并使得空气进入泵的吸入进口管道。
