中文摘要:  随钻测井资料特别是随钻方位性测井资料在地质导向钻井中起着至关重要的作用,可以预测和判断地层界面、地层方位特征以及各向异性地层走向。通过介绍随钻电磁波电阻率仪器、方位深探测电磁波电阻率仪器和方位伽马仪器的基本结构及测量原理,结合实际应用环境,分析了测量仪器在穿越地层界面时的影响因素和边界效应,进而提出了利用电磁波电阻率和方位伽马曲线响应特征实现地层界面识别的方法,最后举例说明了随钻电磁波电阻率和伽马成像仪器在地层界面识别中的应用。现场应用表明,研究开发的具有边界探测能力的地质导向技术和装备,优化了井眼轨迹在储层中的位置,降低了打穿油层的风险,提高了储层钻遇率。

 

英文摘要:Logging-while-drilling data, especially logging-while-drilling azimuth data, which plays an important role in geosteering drilling, can be used to predict and judge formation boundary and azimuth, and strike of anistropic formation. In this paper, the basic structure and principle of three instruments are presented, containing logging-while-drilling electromagnetic-wave resistivity, logging-while-drilling azimuth detecting electromagnetic-wave resistivity, and logging-while-drilling azimuth gammy-ray. Furthermore, both influencing factors and boundary effect while these instruments pass through formation boundary are analyzed, and methods are developed to identify formation boundary by using response features of both electromagnetic-wave resistivity and azimuth gammy-ray curves. In addition, the application of logging-while-drilling electromagnetic-wave resistivity and gammy-ray imaging instruments to identifying formation boundary is also demonstrated. Results show that these two instruments detecting formation boundary can optimize the location of wellbore trajectory, decrease the risk of penetrating oil layers, and increase the drilling rate.
