摘要
地质勘测中,确保勘测数据的精准并能够随时根据钻井情况调整姿势是钻井工程的技术关键。当前国内外随钻测量系统通信技术主要是基于脉冲数据传输方案,这种技术传输性能弱、局限性大。引入随钻测量无线电磁传输技术解决钻井通信问题,基于BPSK(Binary Phase Shift Keying)调制方案,对通信传输系统进行优化,并做通信实验测试。结果表明BPSK方案能很好提升信号宽带能力,传输速率达到100 bit/s,误码率<0.1%,有效解决载波问题,同时工频信号与噪声信号抗干扰能力进一步提升。研究内容对地质钻井平台精准控制具有较大意义。
In the geological survey,to ensure the accuracy of the survey data and to be able to adjust the posture according to the drilling situation at any time are the key technical points in drilling engineering.At present,the communication technology of measuring while drilling at home and abroad is mainly based on pulse data transmission scheme,which has weak transmission performance and large limitations.Therefore,this study introduces the wireless electromagnetic transmission technology of measuring while drilling to solve the drilling communication problem.Based on the BPSK(Binary Phase Shift Keying)modulation scheme,this study optimizes the communication transmission system and conducts the communication experiment.The results show that the BPSK scheme can improve the broadband capability of the signal very well,with the transmission rate reaching 100 bit/s and the bit error rate solution being less than 0.1%,and hence can effectively solve the carrier problem.Meanwhile,the anti-interference ability of power frequency signal and noise signal is improved.The findings of this study are of great significance to the precise control of geological drilling platform.
