摘要
介绍了一种新型的井斜预警系统的地面接收仪器,由井下的机械式井斜预警工具随钻监控井斜,并发生泥浆压力脉冲波,由地面接收仪器测量脉冲波,分析了对信号传递过程中干扰信号的处理方法,经多次现场试验该系统工作良好,可提高工作效率,降低钻井成本。
A new type of the surface receive instrument of Early-Warning System for well inclination is introduced.The downhole mechanical Early-Warning tool monitors deviation with drilling and generates the mud pressure pulse which is detected by the surface receive instrument.The interference signal in the process of the signal transmission is analyzed.The field tests prove that the system can enhances work efficiency and reduces drilling cost.
