摘要
偏轴防斜钻具是一种新的防斜钻具,其井底钻具组合受力分析比较复杂。对偏轴钻具井底钻具组合受力分析模型进行了探讨。依据该理论模型研究设计的偏轴钻具组合在辽河油田进行了现场试验,取得了比较好的效果,既控制了井斜,又保持了较高的机械钻速。
<abstract>centric BHA is a new deflection controlling tool. It' s difficult for us to analyze the stress of eccentric BHA. The paper probed into the theory model of it. The eccentric BHA based the theory model was carried out field testing in Li aohe Oil Field. Good results have been gotten. Borehole deflection was controlled and high penetration rate was also kept.
