摘要
长庆油田水平井由于地质中途电测原因,将二开斜井段分为中测前第一增斜段和中测后第二增斜段,通过应用"两趟钻"钻井技术模式,完钻前仅在中测位置起下钻一趟,减少了钻头使用数量和起下钻次数,钻井速度得到大幅提高.该技术模式在长庆油田水平井应用中取得了显著效果.
For the reason of geological electrical testing in midway of horizontal wells of Changqing Oilfield, two open-inclined segment were divided into the first oblique increasing segment before measurement and the second oblique increasing segment after measurement. And then, through application of "Twice Drilling Technology", it only needs once drill at measure position,and number of drill bit and driling trip reduces, drilling speed has been greatly improved, the technology has achieved remarkable result in horizontal wells application in Changqing Oilfield
