空气钻井关键技术及施工实例分析

Analysis of key technology and construction of air drilling

气体钻井技术是欠平衡钻井的一个关键分支,它的主要特点在于循环介质是空气,最早应用于美国,现在已广泛应用于传统油气井以及非常规油气井的钻探和开发,在油气田开发中占有非常重要的地位,但是我国一些地区对其关键技术的使用还不甚清楚,不能合理选择和使用空气钻井技术。基于此,文章对空气钻井关键技术进行了详细的分析,并选取实例研究了空气钻在使用过程中的注意事项,给正确认识和合理使用空气钻井技术提供了指导和参考。

Gas drilling technology is under balanced drilling a key branch,its main characteristic lies in the circulating medium isair,the earliest application in the United States,and now has been widely used in the traditional oil and gas wells and unconventionaloil and gas well drilling and development,plays a very important role in oil and gas field development,but in some areas of ourcountry on the use of key is not very clear,not a reasonable selection and use of air drilling technology. Based on this,the key on airdrilling technology were detailed analysis,and selected case studies of air drilling in the matters needing attention in using process,tocorrectunderstanding and rational use of air drilling technology to provide guidance and reference.
