FEWD地质导向技术在超薄油藏水平井钻井中的应用

Application of FEWD geo-steering for drilling in ultra-thin reservoir

超薄油藏钻井技术难点大,目前多采用水平井技术,且需要FEWD地质导向技术提供技术支撑。本文针对利用FEWD形成的地质导向技术,对该技术的测量参数、技术优势以及在工程施工中发挥的具体作用做了基本的概括。结合已经完成的超薄油藏水平井钻井作业,定性、定量分析了随钻测井曲线的特点及如何根据曲线分析结果控制井眼轨迹。

FEWD geo-steering technology is applied as technical supports for horizontal wells that are used in ultra-thin reservoir drilling. The paper presents the measurement parameters, features of the technology and its specific role that plays in engineering construction. Besides, quantitative and qualitative analysis of the FEWD curve characteristics are carried out to control well trajectory combined with finished drilling horizontal wells in ultra-thin reservoir.
