广东龙归盐矿区堵漏技术之浅谈

Brief Discussion on Leakage Stoppage Technology in Longgui Salt Mining Area in Guangdong

广东龙归盐矿区矿层顶板处(第三含水带)在钻进中严重漏失,曾经有地质队在同一井场(相距10m)施工过两个钻孔(一直、一斜井),均因堵漏失败而前功尽弃。2012年,我队在该井场施工的龙归20-1直井,利用压力平衡原理进行堵漏和监控,很好地解决了该矿区堵漏老大难问题。

The drilling to the bed top（3rd water hose） of longgui salt mining area in Guangdong occurs serious leakage,and the geological team have ever constructed two boreholes（one is vertical shaft and the other is inclined shaft）in the same wellsite（the distance between two boreholes is 10m）,but both are failed due to the failure of leakage stoppage.In 2012,the Longgui 20-1 vertical shaft that constructed by our team solved the leakage stoppage problem in this mining area by using pressure balance principle to carry out laking stoppage and supervisory.
