【摘要】：针对当前煤矿井下定向钻进技术与仪器无法判识地层,且钻进效率和煤层钻遇率低等不足,以煤系的自然伽马为地层识别依据,通过自然伽马测量技术、信号有线传输技术和信号解调技术等手段,研制了基于自然成功的矿用有线地质导向随钻测量装置,并配套开发了地质导向钻进技术工艺,该装置在2个煤矿进行了试验。试验结果表明:煤系的自然伽马可用于评估钻头位置的地层信息,结合钻孔轨迹参数测量,控制钻孔沿着预定方向在目的地层中延深,降低了分支孔施工数量,为提高煤层钻遇率、探明矿区地层地质信息、保障钻探施工安全及提高钻探施工效率提供了有效手段。
[Abstract]:In view of the deficiency of the current directional drilling technology and instrument in coal mine, such as low drilling efficiency and coal seam drilling rate, taking the natural gamma of coal measure as the basis of formation identification, the natural gamma measurement technology is adopted. Based on the technology of signal wired transmission and signal demodulation, a measurement device for mine wired geological guidance while drilling is developed based on natural success, and the technology of geological guided drilling is also developed. The device has been tested in two coal mines. The test results show that the natural gamma ray of coal measures can be used to evaluate the formation information of bit position, combined with the measurement of drilling trajectory parameters, the drilling hole can be controlled to extend deep in the destination layer along the predetermined direction, and the construction number of branch holes can be reduced. It provides an effective means to improve the rate of coal seam drilling, to ascertain the geological information of strata in mining area, to ensure the safety of drilling construction and to improve the efficiency of drilling construction.
