FEWD地质导向测量技术及应用

FEWD geologic steering of measurement technology and application

江苏油田地质条件复杂,油气藏分布分散且规模小,常规方法开发效益低,现已进入开发中后期,开发难度更大。为此油田引进哈利伯顿公司的FEWD(Formation Evaluation While Drilling)系统以实时跟踪钻井作业,根据地层自然伽玛以及地层电阻率及时调整井身轨迹,提高油气的暴露程度。该仪器投入使用后,性能稳定,数据可靠,开发效果显著。简要介绍了FEWD系统的基本工作原理,并对该仪器在施工准备、施工过程中的一些关键问题进行了分析和阐述,提出了相应的解决办法。

The geological of Jiangsu oilfield is such complex, oil and gas reservoirs distributes disperse and is in small size, normal ways to exploit is inefficient. Now it is in the late period of exploitation and becomes more difficult. Therefore our oilfield introduces the FEWD （Formation Evaluation Whiling Drilling） system from Halliburton Company in order to real-time track the drilling operation. The system adjusts the trajectory of wellhole timely according to the natural gamma and resistivity of formation, improves the degree of exposure of oil and gas. After the instrument is put into use, it has stably performance, provides reliable data and improves the efficient a lot. The document briefly introduces the basic principles of FEWD system, analyses and explains some key issues during the preparation of Job, and provides the correspond solutions.
