一种随钻地面与井下数据交互方法及系统
摘要：
本发明公开了一种随钻地面与井下数据交互方法及系统，该系统包括：设置在钻杆上的井下无线收发工具，其与井下随钻测量工具连接，获取所述井下随钻测量工具实时测量得到的井下测量数据；地面投掷装置，其将微型无线收发模块从地面投掷于所述钻杆的流体通道内；所述微型无线收发模块在经过所述井下无线收发工具时，其通过无线通信方式接收所述井下无线收发工具所获取的井下测量数据，然后，加载了井下测量数据的微型收发模块从所述钻杆中穿出，进入至所述钻杆与井壁之间形成的环形空间中，最后，其跟随泥浆循环旋转返回至地面上。本发明中，采取无线传输方式进行数据传输，使用泥浆作为载体，保证了随钻地面与测量数据的实时快速交互。
摘要（英）：

The invention discloses a while-drilling (WD) ground and downhole data interaction method and system. The system comprises a downhole wireless transceiver tool and a ground throwing device, wherein the downhole wireless transceiver tool is arranged on a drill rod and is connected with a downhole MWD (Measurement While Drilling) tool, so as to acquire downhole measurement data obtained by the downhole MWD tool through real-time measurement; the ground throwing device is used for throwing miniature wireless transceiver modules into a fluid passage of the drill rod from the ground; when the miniature wireless transceiver modules pass through the downhole wireless transceiver tool, the miniature wireless transceiver modules receive the downhole measurement data acquired by the downhole wireless transceiver tool in a wireless communication manner, and then, the downhole measurement data loaded miniature wireless transceiver modules penetrate out of the drill rod, enter an annular space between the drill rod and the wall of a well and finally cyclically rotate along with mud, so as to return to the ground. According to the method and the system, data transmission is carried out by adopting a wireless transmission manner, and the mud is used as a carrier, so that the real-time quick interaction between the WD ground and the measurement data is guaranteed.
