为了达到进一步提高油田采收率和产率的目的,在储层范围内以一个与给定边界较为理想的距离进行钻井十分重要。目前,地质导向钻井技术的作用是毋庸置疑的。随钻测井传感器在地质导向上使用十分广泛。结合现用的两种传感器的优点,以电磁传播为基础,一种新型方位深电阻率传感器可探测井眼轨迹18ft(5·5m)的侧向深度,这有助于确定侵入的方位;并且,在沙特阿拉伯一口油井中对其进行了性能研究,结果表明,该传感器在性能上具有很大优势。
For the purpose of further enhancing oil recovery and productivity, it is important to drill a well within a reservoir range at an ideal distance from a given boundary. At present, the role of geosteering drilling technology is beyond doubt. LWD sensors are used geologically for a wide range of applications. Combining the advantages of the two active sensors, a new azimuthal resistivity sensor based on electromagnetic propagation can detect a lateral depth of 18 ft (5.5 m) of the wellbore trajectory, which helps to determine the orientation of the intrusion; and , Conducted a performance study in an oil well in Saudi Arabia, the results show that the sensor has great advantages in performance.
