在煤田地质勘探钻进中,经常会遇到钻孔坍塌、掉块、缩径等事故。郑州祥隆地质工程有限公司在广泛收集有关资料、反复试验的基础上,在生产施工中进行了广谱护壁剂(GSP)泥浆护壁、防塌的应用研究。介绍了广谱护壁剂的物化性质、泥浆性能,泥浆试验情况及在金龙矿区、超化矿区的应用情况,并总结了广谱护壁剂的使用、维护经验。
Geological exploration in coal drilling, drilling often encountered collapsed, dropped pieces, such as reduced diameter accident. Zhengzhou Cheung Lung Geological Engineering Co., Ltd. extensive collection of relevant information, based on trial and error, carried out in the production of construction of broad-spectrum protective agent (GSP) mud retaining wall, anti-collapse applied research. The physical and chemical properties, mud properties, mud tests and application of broad-spectrum protective agent in Jinlong mining area and super-mining area are introduced. The experience of using and maintaining of broad-spectrum protection agent is summarized.
