反循环空气锤及其在气体钻井中的应用前景

Reverse Circulation of Air Hammer and Its Application in Gas Drilling

在介绍常规空气锤钻井技术及其应用的基础上,研究了反循环空气锤在国内外的发展现状,分析总结了反循环空气锤用于气体钻井所能发挥的技术优势。反循环空气锤在油气勘探钻井领域具有广阔的应用前景,研制开发适合气体钻井用的反循环空气锤具有重要现实意义。

Based on the introduction of the air hammer drilling and its applications, the reverse cir- culation air hammer and its development at home and abroad are studied emphatically. The advan- tages of reverse circulation air hammer used in gas drilling are analyzed and summarized systemat- ically. According to comprehensive analysis, the conclusion that reverse circulation air hammer has application prospect in exploration and development of oil and gas. To research and develop re- verse circulation air hammer fitted the conditions of petroleum drilling is meaningful.
