摘要

摘要: 针对煤矿井下水平井钻探中顶底板界面探测精度差、效率低等问题，进行煤矿井下防爆型随钻方位电磁波测井仪方案设计。为适合井下煤层工作环境，通过正演模拟获得源距、发射频率、线圈安装角度等仪器参数对信号响应影响的变化规律。研究结果表明：随钻方位电磁波仪器接收信号强度随发射频率、线圈距、地层电阻率对比度的增大而增强；线圈安装倾角约为45°时，既满足接收信号灵敏性，也满足信号的强度；仪器最佳工作频段为100 kHz~1 MHz。通过随钻方位电磁波测井仪响应模拟研究，为适用于煤矿井下仪器的参数优化设计提供选择依据，掌握了煤岩顶底板界面响应变化规律，该仪器的应用将提高顶底板探测精度和探测效率。

Abstract: Aiming at the problems of poor detection accuracy and low efficiency of roof and floor interface in horizontal well drilling in coal mine, the design idea of explosion-proof azimuth electromagnetic wave logging tool while drilling in coal mine is put forward. In order to suit the working environment of underground coal seam, the influence of instrument parameters such as source distance, transmitting frequency and coil installation angle on signal response was obtained by forward simulation. The results show that the received signal strength of the azimuth electromagnetic wave instrument while drilling increases with the increase of transmitting frequency, coil distance and formation resistivity contrast; When the coil installation angle is about 45 degrees, it satisfies not only the sensitivity of the received signal, but also the intensity of the signal; the optimum working frequency band of the instrument is 100 kHz to 1 MHz. Through the simulation study of the response of azimuth electromagnetic wave logging while drilling tool, the selection basis for the parameter optimization de-sign of underground instrument in coal mine is provided, and the changing law of the interface response of coal and rock roof and floor is mastered. The application of this tool will improve the detection accuracy and efficiency of roof and floor detection.
