Establish the erosive wear mechanism of drilling string in air drilling and put forward that erosion wear is a substantial cause to promote drill string failure.───初步确立了空气钻井钻柱冲蚀磨损机理,提出钻屑冲蚀是促使钻具失效的一项重要原因。
comparison with the traditional method of drilling shows that the seismic attribute method can locate the coal erosion boundary accurately.───与传统钻探解释方法相比,地震属性方法能够更准确地圈定煤层冲刷带的边界。
Based on data review, the corrosion and erosion of metal drilling tools in under-balanced drilling are analyzed, including affecting factors, composition and application of corrosion inhibitors.───在对文献调研的基础上,综述了国内外在欠平衡钻井中对金属钻具的腐蚀与磨蚀方面所做的工作,主要包括各种影响因素的分析、相应防腐剂的组成和应用。
