通过AKT2孔的施工,可以较为全面的取得该区域各项水文地质参数,用于评价地热资源,为开采地热能提供依据。以新疆温泉县博尔塔拉河谷地地热资源预可行性勘查项目AKT2号勘探孔为研究对象,在对该钻孔地质条件全面分析的基础上,对AKT2钻孔卡钻的事故背景和事故原因进行分析,并提出了具体的事故处理方法和施工建议,从而对后续易发生事故段进行有针对性的提前预防,做好已知地层的取芯工作,进而保证后续工作的正常开展。
Through the construction of AKT2 hole, the hydrogeological parameters in this area can be obtained more comprehensively, which can be used to evaluate geothermal resources and provide the basis for geothermal energy exploitation. Taking the exploration site AKT2 of the pre-feasibility study of geothermal resources in Bortala River valley, Wenquan County, Xinjiang as the research object, based on a comprehensive analysis of the geological conditions of the borehole, the accident background and cause of the accident of the AKT2 drilling stuck- Analyzes and puts forward specific accident handling methods and construction suggestions so as to prevent targeted follow-up accidental sections in advance and prevent core accidental damage. Therefore, core coring of known stratum is well done and the follow-up work can be carried out normally.
