摘要
珲春杨金沟钨矿区地质构造复杂,水敏性地层、力学不稳定地层交互出现贯穿始终,地层造浆严重,钻孔漏失坍塌,多体系泥浆的成功应用,解决了在此矿区钻探的难题。
In Hunchun Yangjingou tungsten mining area, the geological structure is complex, water sensitive formation, mechanics instability formation occurred interactively, Stratigraphic mud-making serious, borehole collapse. Successful application of multi-system mud, to solve the drilling problem in this area.
