所以常常容易因为溢流井与逃气道位置设计不当，使得铸件产生气孔的缺陷。
So often easily design overflow and air vent at inappropriate location, making casting generated gas hole.
溢流井是城市截流式合流制排水系统的一个重要组成部分，它的成败直接影响着规划设计意图的实现。
In urban sewer design, the accomplishment of design intention is effected directly by the function of overflowing well, an important structure for combined sewer system with collector.
溢流关井的水击压力关系到能否关井，以及关井方式的选择。
The surge pressure of overflow well shut-in impacts whether well can be shut down and the choice of well shut-in modes.
高含硫地质环境下钻井溢流发生时，及时关井非常重要，但关井产生的水击压力，可能使防喷器超压，而且易在井内最薄弱的环节发生压漏地层事故。
However, the water hammer pressure produced upon well shut-in will possibly exert over-high pressure on BOP, and the weak points in the well are subject to being fractured.
安装井下防喷器的目的是在发生井涌或溢流的时候，从井下源头附近就能够阻止井喷。
When well, the purpose of installing Downhole Blowout Preventer in the event of overflow which from the underground near the source.
使之在钻井、完井、固井过程中不发生溢流(井喷)或井漏事故，从而实现安全，快速，低成本钻进。
In well drilling and completion, cementing the process does not overflow occurs (at) or well leakage accidents, and realize safe, rapid and low cost of drilling.
反弹溢流是一种比较复杂的井控问题。
一旦出现溢流就会出现溢流量大，溢流速度快，关井压力高等特点，严重的可能最终导致井喷或井喷失控。
While these Wells begin to overflow, Those rapid overflow speed and high pressure shut-in, or serious blow-out or a blowout could ultimately lead to loss of control.
