Detonation Method for Reperforation in Horizontal Wells

陈锋 ,袁吉诚 .水平井再射孔的起爆方法 .测井技术 ,2 0 0 0 ,2 4(1) :74～ 77水平井再射孔的起爆是水平井再射孔的关键技术。分析了水平井再射孔的目的 ,重点介绍了再射孔的 4种实施方案 ,涉及作业管柱的构成、下井工具的结构及工作原理、各方案的优缺点和应用情况 。

Detonation is the key technique for reperforation in horizontal well. Reasons for reperforation in horizontal well are analysed. And four operation schemes are introduced, involving the constitution of working string, the structure and operation principle of downhole tools, the advantages and shortcomings of each scheme and field examples. The detonation schemes introduced herein are a good reference for operation design when reperforation is performed in horizontal wells.
