摘要
本文介绍了作者新研制的“WH—13—Ⅰ型”和“WH—13—Ⅱ型”双管底喷式绳索取心钻头。经在云南省祥云县马厂青矿区复杂地层内实际钻进表明,该钻头结构合理,可实行分层钻进并取得了很好的技术指标和经济效益。
The tungsten carbide wireline core bits with the bottom discharge of type WH- 13-Ⅰ and WH- 13- Ⅱ ,developed originally by the authors ,are introduced in this paper .The practical drilling in complicated formations in Xiangyun county , Yunnan Province indicates the correctness of bit design and the possibility of drilling different formations with corresponding bit . Here the excellent technical and economical effects have been got .
