摘　　要：旋转导向工具是进行大位移钻井系统准确钻进的关键装置,它是一个多参数的测控系统,测量的状态变量包:方位参数、温度、压力等,这些状态参数的获得是导向的前提和基础;文中提出了一种能够应用于钻井工具的黑匣子改进方案。黑匣子就是用于记录旋转导向工具的状态信息和井眼轨迹等数据的装置;以往的数据回收采用-2串口进行,传输速率一直是瓶颈问题,特别是对于海量数据的传输,本文对以往的数据回收方案做了改进,设计和实现了基于USB的井下黑匣子数据回收系统。Rotary steering tools is a core part of the rotary steerable drilling system, it is a multi-parameter measurement and control system , rotary steerable drilling tool state parameters：temperature, pressure, tool face angle, well deviation angle, azimuth, these state parameters obtained oriented prerequisite and basis for;This paper is focus on the rotary steerable drilling tool downhole black box data recovery improvement program. The black box is the rotary steerable tool used to record status information and borehole trajectory data device;Previous data recovery using RS-232 serial transmission the speed has been the bottleneck problem, especially for the transmission of vast amounts of data, this paper on data recovery program improvements, design and realization of USB-based underground black box data recovery system.
