| 摘 要： | 在深孔、定向孔钻进过程中，对钻孔轨迹的控制十分重要。电磁随钻测量系统能够监测钻孔状态参数并通过无线电磁波实时传输至地面，具有信号传输速率高、不受钻井液影响等优势。详细阐述了一种自主研发的电磁随钻测量系统及试验情况，试验最大孔深为609 m，此时地面接收信号高达200 mV。试验研究表明：该系统性能可靠，完全能够满足随钻测量近钻头处钻孔状态及环空压力、温度等参数的需求。

| Abstract: | Well track control is important in drilling deep well and directional well.The electromagnetic measurement while drilling system can monitor and transmit the state parameters of borehole to ground device by wireless electromagnetic wave. This system is applied widely for its high transmission rate and getting none influence from drilling fluid.The paper elabo-rates a self-developed electromagnetic measurement while drilling system in China and its test situation, which can receive signal up to 200mV from borehole of 609m in depth.The experimental research shows that this system is reliable and can satisfy the requirement of the annulus pressure, temperature and other parameters near the bit. |
