Design of signal generator for mine-used mud pulse wireless measurement while drilling

  • 摘要: 针对煤矿井下定向钻进小泵量、低压力工况,研制了一种矿用泥浆脉冲无线随钻测量装置,分析了该装置的技术要求、结构组成、使用条件;重点阐述了该装置信号发生装置(矿用泥浆脉冲无线随钻测量信号发生装置)的设计方案,介绍了信号发生装置中防爆驱动短节及其电磁阀、脉冲发生器的结构设计,以及脉冲发生器中流道控制阀及其阀头参数设计。现场试验结果表明,信号发生装置能够稳定、可靠地产生泥浆压力脉冲信号,最大信号传输深度达2 570 m,泥浆压力脉冲衰减速率为5.8%/100 m,衰减速率低,具备向更深钻孔应用的能力。
    Abstract: For working conditions of small pump capacity and low pressure of directional drilling in coal mine underground, a mine-used mud pulse wireless measurement while drilling (MWD) device was developed, and technique requirements, structure composition and application conditions of the MWD device were analyzed. Design scheme of signal generator in the MWD device, namely signal generator for mine-used mud pulse wireless MWD, was focused on. Structure design of explosion-proof driving section and its solenoid valve in the signal generator as well as pulse generator, and design of liquid passageway control valve and its valve head parameters in the pulse generator were introduced. The field test results show that the signal generator can generate mud pressure pulse signals stably and reliably with the maximum signal transmission depth of 2 570 m and low mud pressure pulse attenuation rate of 5.8%/100 m, which has ability to apply to deeper boreholes.
