开展缩小井距开发先导试验,通过适当加密井网,建立有效生产压差,改善开发效果。
To make the development effect better, we reduce well spacing to develop the precursor experiment, infill well network appropriately, build effective producing pressure drop.
在部分负荷的条件下,利用动态平衡阀是防止气蚀的有效方法,因为它减少了通过平衡阀的压差。
Under part-load conditions the use of a dynamic balancing valve is a more effective method to prevent a cavitation as it reduces the pressure drop across a balancing valve.
每一个有效节能的供热系统都配有相应的调节控制设备,如自力式流量控制阀、压差控制阀等。
An effective and energy saving heating system needs many control devices, such as flow controllers and differential pressure controllers.
