旋转地质导向技术在NP-8三维水平井钻井中的应用

Application of Rotary Geological Steering Technique in the NP-8 Three-Dimensional Horizontal Well

摘要: 旋转地质导向技术是旋转导向技术与地质导向技术的有机结合形成的尖端自动化钻井技术。在三维评价水平井NP-8井钻井中成功应用随钻岩性识别、随钻油气特性识别技术以及地质建模、实时跟踪、实时调整导向工具姿态的旋转地质导向技术,有效地控制三维井眼轨迹准确着陆、精确入靶，并在薄主力油层中延伸1835米。并为有效治理井下复杂事况提供数据支持。为后继旋转地质导向技术在致密油藏三维水平井钻井中的应用提供了借鉴作用。

Abstract: Rotary geological steering technique is the tip automatic drilling technology with the combination of geosteering technology and rotary steering technology. In the drilling of 3D evaluation horizontal well NP-8, rotary geological steering technique is applied to lithology identification while drilling, oil and gas properties recognition technology, geological modeling and real-time tracking, real-time adjustment. It effectively controlled the accurate landing and targeting of 3D well trajectory, extended 1835 m in the thin layer and provided data support for the effective governance of downhole accidents. It provides a reference for the application of rotary geosteering technique in 3d horizontal drilling in tight reservoir.
