摘要
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，与目前国内常用测并作业方式相比，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 Compact well logging system made by Weatherford recently.The system can be used in highly deviated wells,horizontal wells and complicated without wireline.The tool is fixed inside the drill stem with a shuttle -type transport unit.After arriving at the target zone,it is pumped out through pressure,then acquire data which will stored in the internal memory in the downhole tool.It can achieve induction,dual lateral,high-resolution shallow resistiviity,lithology density,caliper,GR,neutron porosity,acoustic slowness acoustic slowness,well deflection and temperature logging,etc.It is more reliable,lower cost,time savings and smaller risk and it has prospect of widespread use.
