弱胶结砂砾岩地层钻头研制及提速工具配套研究
|
摘要
针对弱胶结砂砾岩地层钻井过程中面临的PDC钻头崩齿、碎齿严重,钻头先期损坏使得单只进尺少,钻井成本高等技术难题,从弱胶结砂砾岩地层岩石力学特性分析、锥齿PDC钻头研制及提速工具配套等方面着手,研究形成了适合弱胶结砂砾岩地层钻井提速的锥齿微心PDC钻头;并通过选用恒扭矩工具配合该型钻头在胜利油田利567区块进行现场应用,取得了良好的效果,大大延长了钻头的使用寿命,起到了提高机械钻速和降低钻井成本的目的。
The burial depth and complex formation lithology of poor cemented sandy gravel reservoirs make the drilling operation face some difficulties, such as low ROP, reduced footage. The paper studies the technologies of bit optimization and improvement of tool selection to overcome these problems, which achieved good results in drilling at Li567 Block of Shengli Oilfield, in particular with extended service life of the bits. This will provide effective technical reference for the subsequent development of similar blocks.
