Abstract
Disclosed is a data transmission system and a method for transmission of downhole measurement data to the ground. The system includes a drill string mounted with a logging while drilling measurement tool, and a throw while drilling section, which accommodates a micromemory. The throw while drilling section includes a housing which is mounted outside of the drill string as a sleeve to form a clearance space therebetween; a control circuit; and a wireless transceiver. The throw while drilling section releases, under function of a micromemory release instruction transmitted by the control circuit, the micromemory loaded with the downhole measurement data to the ground.
