魔芋胶(MY胶)冲洗液及PAM-水泥-泥浆堵漏液在白山部分矿区复杂地层中的应用

Application of konjac gum flushing fluid and PAM-cement-slurry plugging fluid in complex formation of partial mining area in Baishan

吉林省白山部分区域地质构造复杂,部分矿区地层漏失坍塌严重,魔芋胶(MY胶)冲洗液在遇水不稳定地层、力学不稳定地层钻进过程中成功地解决了成功解决了钻孔坍塌成孔困难及岩心采取率严重不足的难题,PAM-水泥-泥浆堵漏液成功地解决了严重漏失地层的堵漏难题。

The geological structure of partial area in Jilin Baishan is complex, and formation leakage collapsed of partial mining area is serious. In the unstable formation with water and mechanical unstable stratum, Borehole collapse, difficulty to form hole, and the insufficient of core recovery percentage were successfully solved by konjac gum.
