| 中文摘要: |
| 针对地浸砂岩型铀矿内蒙古鄂尔多斯盆地银东地区和巴音戈壁盆地巴音戈壁地区钻进中经常出现钻孔漏失、孔壁坍塌,堵漏时间长等问题而开展的可循环微泡沫泥浆研究试验,较好地解决了地层渗漏水问题,减少了生产用水量,明显提高了机械钻速和岩心采取率,降低了生产成本。可循环微泡沫泥浆钻探工艺不需要投入空压机和增压装置,仅利用现有泥浆泵即可使用,大大降低了钻探成本,有利于推广使用。 |
| 英文摘要: |
| In view of drill leak,hole wall collapse and long-time leaking stoppage during drilling for leaching in-situ sandstone style uranium deposits in the Yindong district of Eerduosi basin and Bayin Gobi district of Bayin Gebi basin,Inner Mongolia,recyclable foam mud was tested.The test solved strata water seepage,decreased water consumption,obviously raised drilling rate and recovery efficiency,and reduced drilling cost.Recyclable foam mud technology could be implemented by using conventional mud pump set witho... |
