文章介绍了威特福公司新近开发的Compact测井系统,该系统可在大斜度井、水平井及井况复杂直井中不使用电缆进行测井作业,利用梭式传输装置将仪器直接安装在钻杆内部,通过钻杆送达目的层位后,加压泵出仪器,采集数据,数据直接存储在井下仪器内部存储器里。能够完成感应、双侧向、高分辨率浅电阻、岩性密度、井径、自然伽玛、中子孔隙度、声波慢度及井斜、温度等测量项目,与目前国内常用测井作业方式相比,具有可靠性高、成本低、节约时间、风险小等特点,具有广泛应用前景。
The paper introduces a newly developed Compact logging system from Weifu that does not use cables for logging operations in highly deviated, horizontal and wellbores. The shuttle is used to mount the instrument directly Inside the drill pipe, after the drill pipe is delivered to the destination floor, the pump is pressurized out of the apparatus to collect data, and the data is directly stored in the downhole instrument internal memory. It can complete the measurement items such as sensing, double-sided, high-resolution shallow resistance, lithology density, borehole diameter, natural gamma, neutron porosity, acoustic slowness and well inclination and temperature, Compared with the high reliability, low cost, save time, the risk of small, with a wide range of applications.
