化学凝胶堵漏剂在胶西北红布矿区的应用

Application of chemical gel plugging agent in the northwest Jiaodong Hongbu mining area

摘要:

胶西北红布金矿位于焦家金矿田中段，但又不是典型的焦家式金矿，是发育在断裂带两侧花岗（闪长）质岩中受密集节理、裂隙控制的细脉、网脉状金矿。因其受焦家主断裂和焦家断裂系河西断裂及侯家断裂三大断裂控制，其所钻遇地层的结构极其复杂。在该矿区最深钻孔127ZK1孔试验应用了化学凝胶堵漏剂，取得了良好的效果。本文重点介绍了127ZK1孔钻进中遇到的问题，以及化学凝胶堵漏剂的室内试验和现场应用效果。

Abstract:

The northwest Jiaodong Hongbu gold deposit located in the middle Jiaojia gold field, but not a typical Jiaojia style gold mine, is a fine net vein gold deposit developed in the granite (diorite) on both sides of the fault zone and controlled by dense cleavage and fractures. Because it is controlled by three major faults, namely the main Jiaojia fault, the Hexi fault and the Houjia fault of the Jiaojia fault system, the geological structure encountered in drilling is extremely complex. In this paper, application of chemical gel plugging agents in Borehole-127ZK1, the deepest hole in the mine is described.
