泥浆脉冲式随钻测量系统在高位定向孔中的应用

近年来，煤矿井下随钻测量系统由于其效率高、精度准的优点，已被广泛应用于煤矿瓦斯治理、地质构造勘探及水害防治中。通过在山西临汾市德通煤业现场实际应用泥浆脉冲随钻测量系统，对比中心通缆式测量装置与泥浆脉冲测量装置的精度和效率，证实新型泥浆脉冲仪器钻进效率高、节约成本、工作稳定，具有高安全性和可靠性的特性。可在高位定向孔中推广应用。

Mud pulse measuring while drilling system usedin high position directional drilling

In recent years, the coal mine MWD system has been widely applied in CBM drainage, geological exploration and prevention and control of water disasters due to its advantages of high efficiency and accuracy. Through the field application of the mud pulse MWD system in Detong Coal Industry of Linfen city, Shanxi Province, the accuracy and efficiency of the wireline survey tool and the mud pulse survey system is compared. The result demonstrates that the mud pulse system can be widely used in high position directional holes.
