壳牌勘探与开发公司在墨西哥湾深水区Auger张力腿平台上连续采用控制压力钻井(MPD)技术进行小井眼侧钻,使用动态环空压力控制系统成功钻出了4口侧钻井,没有出现漏失和井眼失稳情况,提高了钻井效率。使用该技术可钻进由于亏空引起破裂压力梯度减小的层段,在钻进过程中不会发生卡 Shell exploration and development company continuously piloted Slim Hole Drilling with controlled pressure drilling (MPD) on the Auger tension leg platform in the deepwater Gulf of Mexico, successfully drilled a 4-lateral well using a dynamic annulus pressure control system without loss and Borehole instability, improve drilling efficiency. Using this technique can drill into the interval due to the collapse of the pressure gradient caused by a shortfall, the card does not occur during drilling
