摘要: 提出了煤矿井下泥浆脉冲无线随钻测量定向钻进技术,介绍了技术原理,分析了泥浆脉冲无线随钻测量、双动力复合定向钻进和双动力复合排渣3项关键技术,集成了泥浆脉冲无线随钻测量系统和高强度钻杆在内关键配套装备。试验结果表明:顺利完成了孔深3 353 m超长定向钻孔施工,终孔时最大泥浆泵压力仅为额定压力的43.8%;在破碎的复杂顶板中完成5个高位定向钻孔,最大成孔深度540 m,总进尺1 653 m,使用泥浆脉冲无线随钻测量系统累积测量551次,其中误码4次,综合误码率仅为0.72%,系统有效工作时间在20 d以上。Abstract: The directional drilling technology with mud pulse wireless MWD in coal mine was presented. We introduce the principle of the technology and analyze three key technologies: the wireless MWD with mud pulse, the compound directional drilling and the compound slag discharge with dual power, and integrate the key supporting equipment including wireless MWD with mud pulse and high strength drill pipe. The test results show that the construction of super-long directional drilling with hole depth of 3 353 m was successfully completed, and the maximum mud pump pressure at the end hole was only 43.8% of the rated pressure. The five directional drilling holes were completed in the complex broken roof, the maximum depth of the hole is 540 m, and the total length is 1 653 m. The mud pulse wireless MWD was used for 551 cumulative measurements, of which 4 were error codes, with a combined bit error rate of 0.72%, and the effective working time is more than 20 days.
