短弯外壳导向钻具的造斜率计算

BUILD-UP RATE CALCULATING ON SHORT BENT HOUSING MOTOR

    摘要
  • 摘要: 根据短弯外壳导向钻具在井眼中的选料特性,推导了导向钻具组合造斜率车的计算公式,方法是精确的,没有做近似处理。这种方法还能考虑近钻头扶正器的欠尺寸影响,可对在井眼轨迹控制中使用的单弯和双弯导向钻具组合进行预测计算。这种方法易编成计算机程序,在现场使用。

     

    Abstract: According to the building property of short bent housing motor,the formula to calculating motor’s build-up rate was derived which can consider the effect of near bit undergauge stabilizer and predict the building rate of single or double bent motors used in directional drilling.
