基于定向钻进原理,探讨了深孔定向钻进技术的优缺点,并结合冀中能源东庞矿的实际条件,分析了深孔钻进技术在煤层瓦斯抽采中应用的可行性。通过对高位定向长钻孔在抽采过程中的瓦斯浓度及流量进行观测分析,确定了利用定向钻孔进行高位瓦斯抽采方法的有效性,从而为深孔定向钻进技术在瓦斯治理方面的推广应用提供了一定的技术支持。
Based on the principle of directional drilling, the advantages and disadvantages of deep hole directional drilling technology are discussed. Combined with the actual conditions of East Pangang in Jizhong Energy, the feasibility of deep hole drilling technology in coal seam gas drainage is analyzed. Through the observation and analysis of the gas concentration and the flow rate in the process of high directional directional long borehole drilling, the effectiveness of high-level gas drainage by directional drilling is confirmed, and the result of deep hole directional drilling technology in gas treatment Promote the application of a certain degree of technical support.
