澳大利亚AMT公司成功开发出一种新型定向钻进监测系统,它可在钻进过程中对钻孔进行快速而又简便的测量.这种名DDM-MECCA 的监测系统由孔口监测箱、钻杆和孔底探头3部分组成.传统的定向钻进监测系统采用照像系统对钻进方向进行监测,每次测定都需要将孔底照像机取出进行数据分析,数据获取时间约1h,而新系统通过测定钻孔行进时的地磁重力变化,了解钻孔的行进方向,有关数据可通过电缆传至地面进行实时处理,数据获取时间仅为5s.
Australia AMT has successfully developed a new directional drilling monitoring system that enables quick and easy measurement of drilling during drilling. The DDM-MECCA monitoring system consists of an orifice monitoring box, a drill pipe And the bottom of the hole probe 3. The traditional directional drilling monitoring system uses the camera system to monitor the drilling direction, each measurement requires the bottom of the hole camera for data analysis, the data acquisition time of about 1h, and the new By measuring the geomagnetic gravity change during drilling, the system can know the drilling direction and the data can be transmitted to the ground via cable in real time and the data acquisition time is only 5s.
