钻井自动化

自主定向钻井和地质导向技术增强了实时决策能力

本文提出了一种钻探最大储层接触井的新方法,该方法集成了自动化钻井和地质导向软件来控制井下井底钻具组合,从而最大限度地减少了人为干预的需要。

对于成熟油田的开发而言,钻探最大储层接触(MRC)井至关重要。与现有井或水平井发生碰撞的风险需要全面的实时防碰撞和测量管理。传统上,经验丰富的定向钻井人员依靠其在特定区域对井底钻具组合(BHA)性能的专业知识,根据需要调整钻井参数和钻具组合配置。然而,这种方法常常导致钻井轨迹偏离预期,并因人为错误而造成性能不稳定。

Autonomous Directional Drilling and Geosteering Enhances Real-Time Decision-Making

This paper proposes a novel approach toward drilling maximum-reservoir-contact wells by integrating automated drilling and geosteering software to control the downhole bottomhole assembly, thereby minimizing the need for human intervention.

Drilling maximum-reservoir-contact (MRC) wells is crucial for the development of mature fields. A risk of collision with existing wells or laterals requires comprehensive real-time anticollision and survey management. Traditionally, skilled directional drillers have relied on their expertise regarding bottomhole-assembly (BHA) behavior in specific areas, adjusting drilling parameters and assembly configurations as needed. This approach, however, often results in deviations from the intended trajectory and performance inconsistencies introduced by human error.
