地面井位优选设计新方法

通过合理地选择地面井位,利用地层的自然造斜规律实现地质中靶,可以有效地解放钻压、提高机械钻速和井身质量。所提出的地面井位设计新方法,不仅可以确定出合理的地面井位,而且可以给出井眼轨迹的设计结果,这对实钻轨迹的监测大有益处,其设计方法更具科学性和实用性。还分析了影响地面井位的因素,并给出了地面井位设计和影响因素分析示例。

New Method of Well Location Optimizing Design

The method of hitting a target zone by properly selecting a suitable surface well location, and taking advantage of the natural inclination building tendency of the formation is good for improving the penetration rate and borehole quality. New method of well location design is presented, which can not only determine a suitable surface well location, but can also present a designed result of hole trajectory. This method is more scientific and practical, and is beneficial for hole trajectory monitoring during field drilling. Factors of influencing the optimization of well location are evaluated, and case histories of well location design and influencing factors evaluation are also presented.
