摘要:

针对寨上金矿区钻探中存在的坍塌、缩径等钻孔护壁难题，在采用多种冲洗液无效的情况下，试验应用了植物胶低固相冲洗液，成功地解决了该矿区钻探钻孔护壁难题。分析了矿区钻探护壁困难的原因，介绍了冲洗液应用技术。

Abstract:

Because of the complex formation in Zhaishang gold mine, drilling was difficult with collapsing and diameter shrinkage. Several kinds of drilling fluids were tried to solve these problems with less effect. Experimental application was made on plant gum low-solid mud with ideal result. The paper analyzed the difficult cause of wall protection in the mine and introduced the application techonoly of drilling fluid.
