SEMWD无线随钻仪在沁水盆地煤层气远端水平井钻进中的应用

摘要

为了提高沁水盆地15#煤的煤层气产能，使用先进的无线定向仪器来试验施工水平对接井技术。施工中采用了多种地质导向技术进行对比，验证了仪器的先进性和可操作性，增加了钻进效率和对接精度。试验表明，SEM⁃WD仪器在薄煤层的施工中具有很强的可操作性，性能优越，判断较为准确，对含有夹矸的薄煤层水平对接井施工，具有很大的指导意义。%To improve CBM productivity from coal No.15 in the Qinshui Basin, has used advanced wireless directional devices to test horizontal butted well construction technology. Multiple geological orientation techniques have been compared during construction, ver⁃ified advantage and operability of devices, improved drilling efficiency and butting accuracy. Tests have shown that the SEMWD device has better operability during thin coal seam drilling with superior performance and correct judgment, thus provided with great guiding significance.
