Abstract：WirelessMeasurement-While-Drilling（MWD） technology， is an important part of drilling technology for complex structure wells. In recent years， related technologies have developed rapidly in China， and the technical level has been continuously improved.However， all kinds of complicated situations about MWD application happened one after the other. Taking well X8 as an example， the author analyzes the main influencing factors of MWD application technology， makes statistics on the failure of wireless MWD instruments in the well， analyzes the causes of instrument failure and damage， then puts forward suggestion that wireless MWD technology needs to establish a more perfect wireless MWD application management system in terms of the reliability of measurement equipment and application environment and also suggested  improving the rationality of the application of measurement system to help to improve the MWD technology development。

随着复杂结构井钻井技术需求的日益高涨，无线随钻测量技术发展迅猛，得以大面积普及、应用，大大提高了钻井效率，简化了定向操作难度[1-3]。近年来，随着应用规模的不断扩大，特别是深井和高温高压井的增多，无线随钻测量仪器失效的现象层出不穷。但无线随钻测量应用技术也是一项环环相扣的系统工程，任何环节不匹配都将影响随钻测量的效果，甚至是能否应用成功。从国内相关技术的应用情况来看，无线随钻测量不能正常实施的影响因素很多，主要包括地面设备的功能性、井下测量设备的可靠性、测量环境的恶劣程度、循环系统的工况条件、操作人员的使用水平等。本文以X8井为例对各种影响因素进行剖析。
