Mine-used mud pulse wireless measurement while drilling device and its applicatio

  • 摘要: 针对采用中心通缆式钻杆作为信号传输通道的有线随钻测量装置存在的钻杆结构复杂、机械性能受限、抗干扰能力差等问题,研制了一种矿用泥浆脉冲无线随钻测量装置。该装置由防爆计算机、防爆键盘、防爆数据存储器、防爆测量探管、防爆压力变送器等组成,采用间歇模式工作:防爆测量探管中的测量短节检测到泥浆泵停泵信号后,采集钻孔轨迹参数、定向钻具状态参数等静态数据并进行编码;当检测到泥浆泵开泵信号后,防爆测量探管中的驱动短节依次发送静态数据、测量并发送动态数据,同时控制脉冲发生器调整水力通道的流道面积;防爆压力变送器采集泥浆泵压力信号并将其发送至防爆计算机;数据传输完成后,防爆测量探管停止工作,脉冲发生器内部流道恢复,泥浆泵压力变为正常值,开始定向钻进。试验结果表明,该装置工作稳定,测量数据准确,传输可靠,提高了定向钻进效率和安全性,满足煤矿井下各类煤层孔和岩层孔定向钻进需要,且可实现常规钻孔轨迹随钻测量。
    Abstract: For problems of wired while drilling device (MWD) which used central cable drilling rig as signal transmission channel such as complex drilling rig structure, limited mechanical behavior, poor anti-interference performance and so on, a mine-used mud pulse wireless MWD device was developed. The device is composed of explosion-proof computer, explosion-proof keyboard, explosion-proof data memory, explosion-proof measuring tube, explosion-proof pressure transmitter, etc. It works in intermittent mode. When shutdown signal of mud pump is detected by measuring section of the explosion-proof measuring tube, static data including drilling trajectory parameter and state parameter of directional drilling tool is collected and coded. When opening signal of mud pump is detected, following works are done by driving section of the explosion-proof measuring tube including sending the static data, measuring and sending dynamic data, and controlling the pulse generator to adjust flow channel area of hydraulic conduit. The explosion-proof pressure transmitter collects pressure signal of mud pump and sends it to the explosion-proof computer. When data transmission is completed, the explosion-proof measuring tube stops working, flow channel inside the pulse generator is restored, mud pump pressure is changed to normal value, then directional drilling is started. The test result shows that the device runs stably with correct measurement data and improves efficiency and safety of directional drilling, which can meet directional drilling need of all kinds of coal-seam or rock-seam drilling holes and realize measurement while drilling of traditional drilling trajectory.
