air trap

Based on the close packing and grain composition theory, a new anti-gas channeling lightweight high performance cement slurry system has been developed with industrial drift beads as lightweight additive and superfine gel as strengthening agent.

基于紧密堆积和颗粒级配理论,研制了一种以工业漂珠为减轻剂、以超细胶凝材料为增强剂的新型低密度、高强度防气窜水泥浆体系。

9 g/cm3)cement slurry was required to have properties of low filtration,high early strength,short transition time and gas channeling in low temperature(27-60 ℃).

9g/cm~3)在较低的适用温度(27～60℃)范围内,具有“低失水、高早强、短过渡、防气窜”等特点。

The new anti-gas pump is proposed,which not only cost less and increase pump efficiency remarkable but also completely avoid the "gas locking",and its working.

提出防气泵的防气功能在于清除余隙内的游离气和尽量减少余隙液体中的溶解气。
