Background
The tracer while drilling and the micro memory are novel underground detection while drilling equipment and large data volume transmission equipment, and the tracer passes through a drill bit water hole while drilling fluid in a drilling tool in a well in a mode of well mouth putting or underground releasing, and then circulates to the well mouth in an upward mode to perform whole well circulation and measure shaft parameters. The micro-memory is released from the underground and goes up to the wellhead through the circulation of the drilling fluid, and the underground while-drilling data is carried to the ground. In order to adapt to the throwing while drilling or the well bottom releasing, the diameter of the drill bit is between 7mm and 20 mm. After the drilling fluid returns to the wellhead, the tracer and the micro-memory are recovered, and data are read and processed. And then used for recharging.
