据世界石油2021年8月17日报道，全球最大的油田服务公司斯伦贝谢公司日前宣布，该公司推出了自主定向钻井技术，这个技术包括通过任意井段的自动导向解决方案。 斯伦贝谢公司利用智能和动态的井下自动控制系统，能够即时解释和处理数据，继续推进数字化服务，提高井施工性能。
斯伦贝谢公司井施工总裁杰西·拉马斯表示:：“自主定向钻井技术是行业数字化转型的重大飞跃，帮助我们的客户实现了井施工效率的新水平、一致性和可持续性。随着最新技术的创新，我们的自主导向井底钻具组合(BHA)能够钻穿任何井段。 作为自主定向钻井的四大支柱之一，井下自动化功能可以在遇到条件时驱动转向调整，显著提高机械钻速，提高井眼质量，从而提高生产潜力，降低排放。”
斯伦贝谢公司的自主定向钻井解决方案建立在四个不同的支柱之上：智能规划、智能执行、地面自动化和井下自动化。 为了实现井下自动化，斯伦贝谢公司引入了井下自动化控制系统——一种先进的智能闭环控制装置，能够获取、解释和处理数据，从而更快、更好地钻井。 这个系统能够立即执行修正， 这确保了钻井轨迹的准确度，消除了数据到地面的延迟，从而改善决策的等待时间，提高整体定向钻井效率。 目前的自主定向钻井技术应用包括自动垂直、自动切线和自动曲线。
在中东，一家作业公司使用斯伦贝谢公司的自主定向钻井技术，在四口井中钻出曲线。 与使用手动方式钻井的邻井相比，该组合解决方案使旋转导向系统的下行段减少了49%，同时机械钻速提高了37%。 在二叠纪盆地，一家作业公司使用了类似的解决方案，对7口井的曲线和水平段进行了自动钻取。 作业公司将所有曲线段的下行段减少了42%，同时将机械钻速提高了39%。

Schlumberger introduces autonomous directional drilling
Schlumberger announced the introduction of Autonomous Directional Drilling, which includes solutions to steer autonomously through any section of the wellbore. Leveraging an intelligent and dynamic downhole automated control system that instantly interprets and acts align="justify"> “Autonomous Directional Drilling is a significant leap forward for the industry digital transformation, helping our customers achieve new levels of well construction efficiency, consistency and sustainability,” said Jesus Lamas, president, Well Construction, Schlumberger. “Our autonomous vision continues to evolve, with the latest technological innovations enabling a self-steering bottomhole assembly (BHA) capable of drilling through any well section. As align="justify"> Schlumberger Autonomous Directional Drilling solutions are built upon four distinct pillars: intelligent planning, intelligent execution, surface automation, and downhole automation. To achieve downhole automation, Schlumberger has introduced a downhole automated control system—an advanced and intelligent closed-loop control unit— that acquires, interprets and acts upon data to drill better wells, faster. The system performs corrections immediately. This ensures drilling trajectory accuracy and removes data-to-surface delays to improve decision latency—resulting in greater overall directional drilling efficiency. Current Autonomous Directional Drilling applications include auto-vertical, auto-tangent, and auto-curve.
In the Middle East, an operator used Schlumberger’s Autonomous Directional Drilling to drill curves on four wells. The combined solution enabled the operator to reduce downlinks to the rotary steerable system by 49% as compared to offset wells drilled in manual mode, while achieving a 37% increase in ROP. In the Permian Basin, an operator used a similar solution to autonomously drill the curve and lateral sections for seven wells. The operator reduced downlinks by 42% for all curve sections, while increasing ROP by 39%.
