矿产类的建筑材料在国民经济发展中具有十分重要的地位。但是随着市场对这类资源开采开发力度的增加,其勘探力度和钻探要求也在不断加强和提高,解决好地质钻探中孔壁失稳的问题,对获取地质、矿产信息、开发优质建材和获取原材料有着十分重要的意义。这类原材料广泛的存在于复杂地层中如:优质石材;石膏;磷、硫矿等等。本文对地质钻探中孔壁失稳的问题进行总结、分析和处理。有效的解决了钻探这类地层的实际问题。
Mineral construction materials in the development of the national economy has a very important position. However, as the market increases the exploitation of such resources, the exploration efforts and drilling requirements are constantly being strengthened and improved to solve the problem of instability of the wall of the hole in geological drilling. It is also necessary to obtain information on geology and mineral resources, develop high-quality building materials, Access to raw materials is of great importance. Such raw materials are widely found in complex formations such as: high quality stone, gypsum, phosphorus, sulfur ore and so on. This paper summarizes, analyzes and deals with the problem of instability of the hole wall in geological drilling. Effectively solve the actual problems of drilling such formations.
