摘要
初步分析了高压、大管径、厚壁管道定向钻穿越工程的特殊性和工艺步骤,从设计实例计算分析着手,根据理论和实践相结合的原则详细阐述了穿越曲线的确定方法和回拖阻力的算法,并对定向钻穿越工程的风险控制提出了一些建议和措施。
Particularity and process of directional drilling crossing for those pipelines featuring high- pressure, large diamete, thick pipe wall are analyzed. Combining theory with practice, the author reaches the conclusion of crossing curve and pullback resistance of directional drilling of which measures for risk control are also brought forward.
