我国低渗透油藏的天然弹性能量普遍较小，所以基本上都先后采取了注水保持压力的开发方式。
The original elastic energy in low permeability reservoir is generally small, so all the oil fields early or late adopt water flooding to keep the pressure of the low permeability reservoir.
对于注水开发砂岩油田，保持合理的地层压力既关系到油田开发效果，又影响到油田开发总体效益。
In a water flooded sandstone oilfield, keeping a reasonable formation pressure is important for both the development effect and the total development benefit.
注水是保持地层压力、提高原油采收率的主要措施之一。
Water injection is one of the major measures to keep formation pressure and improve oil recovery.
油田注水是保持油层压力、降低原油递减率的主要措施，注水泵机组是油田注水的关键设备。
Oilfield water injection is the main way to keep the reservoir pressure, and to reduce the crude oil decline.
注水是油田保持地层压力的主要措施之一。
Oilfield water injection is the main measure to maintain the reservoir pressure.
结果：粘土稳定剂对注水井地层提前进行预处理，使注水井压力得到了有效的控制，保持了地层原有的渗透性。
Result Clay stabilizer prelimiarily treats the formation of injection wells, controls efficiently the pressure of injection wells, preserves the permeability of the formation.
并合理补充地层能量，地层压力降至0.85倍饱和压力附近时开始注水，注采比保持在1.0左右。
When formation pressure decreases to around 0.85 times of saturation pressure, water should be injected with the injection-production ratio of some 1.0 to replenish energy.
