西华山钨矿区复杂地层钻进的综合治理措施

Comprehensive Control Measures for Complex Formation in Xihuashan Granite Mine

摘要:

总结了西华山钨矿区综合治理复杂地层的经验；着重介绍了PAA聚合物在断层破碎带、易水化碎裂岩体中的使用方法和护壁堵漏效果；提出了治理复杂地层应采取“‘辨证论治’、灵活运用”的思路方法，最大限度地降低施工成本，提高钻进效率。

Abstract:

Experience was summed up about comprehensive control on complex formation in Xihuashan granite mine; the paper emphatically introduced the application method and the effects of wall protection and leaking stoppage with PAA polymer in fault fracture zone and hydration cataclastic rock. “Differentiation treatment” and “flexible application” were put forward to the control on complex formation for maximum low cost and high drilling efficiency.
