The present application relates to the technical field of self-driven measurement-while-drilling tool, and particularly relates to a self-driven along-drill-string measurement system based on a friction nanogenerator. The technical scheme comprises a friction nanogenerator, an energy management unit, a low-power wireless communication relay node and a ground control terminal. The friction nanogenerator is used to collect the vibration energy of the drill pipe and convert it into electric energy. The friction nanogenerator adopts a sliding independent layer structure and comprises a rotor and a stator. The present application realizes distributed self-driving by deploying the friction nanogenerator at each communication node and utilizing the downhole vibration energy. The energy converted by the friction nanogenerator at the drill bit is enough to emit stronger communication signals, ensuring sufficient energy supply, rapid response of communication content and efficiency, developing information transmission technology with continuous power supply and low-power operation in the process of measurement-while-drilling, and realizing bidirectional communication of information, which has remarkable engineering value for difficult-to-exploit oil and gas resources.
