To obtain accurate temperature and pressure data during downhole fracturing processes, a novel dissolvable fracturing ball is developed for collecting temperature and pressure data during downhole fracturing stages. This method utilizes the fracturing ball as the external structure, with pressure and temperature sensors as the core components for data acquisition. Based on a single-chip integrated circuit, data transmission was achieved through RS-485 communication, and data storage was accomplished via SPI communication. In accordance with the operational conditions of the novel dissolvable fracturing ball, experiments on pressure, temperature, and signal storage ball escape were conducted. The experimental results demonstrate that the design structure of the novel dissolvable fracturing ball meets the requirements of operational conditions, with excellent sensor acquisition accuracy. Its capability to read and store pressure and temperature data during downhole fracturing stages provides new insights for the digital transformation of oil and gas field exploration and development technologies.
