摘要
国内地浸采铀工艺钻孔中尚无成熟的逆向注水泥浆固井技术。为提高地浸工艺钻孔的水泥浆固井质量,设计了一个常闭式桶装柱塞阀逆向注浆装置。该装置通过丝扣连接在井管过滤器上方。注浆过程中,注浆管从井管内下放并与该装置的阀芯对接,由注浆管自重压下弹簧、打开阀,水泥浆即经注浆管、逆向注浆装置的阀向井管外实施逆向注浆。注浆结束后,提升注浆管,注浆阀自动复位关闭。现场逆向注浆试验中试注一个钻孔,注浆深度140 m,注入水泥5.3 t。结果表明,逆向注浆方法可行,注浆效果良好,设计的逆向注浆装置安全可靠,且易于操作。
At present in domestic there is no mature reverse pumping slurry cementing technology.To improve borehole water slurry cementing quality,a closed bottled plunger valve reverse grouting device was designed,by threads connecting above the well pipe filters.Grouting process,grouting pipe is down-passed from well pipe and connects with valve core.The grouting pipe presses the spring by its weight and opens the valve,by grouting pipe,valve reverse grouting device,the slurry starts reverse outside the well tube grouting.Ending grouting,grouting pipe,grouting valve close automatic and reset.Field reverse grouting test,a hole is groutied,grouting depth is 140 m,injecting cement is 5.3 tons.The results show that the reverse grouting method is feasible,the grouting effect is good,reverse grouting device is safe and reliable,and easy to use.
