TY - JOUR AU - Xiao, Meng AB - In response to the current demand for drilling cost reduction, efficiency improvement, and drilling safety in the drilling process, it is necessary to collect a large amount of real-time downhole measurement data to achieve real-time monitoring of wellbore pressure, drilling tool efficiency,and drilling speed.Nowadays,traditional while drilling measuring instruments have disadvantages such as small storage capacity, large volume, and easy loss of power due to power failure.Therefore, designing a downhole dynamic recorder based on NAND (Non-And) large capacity memory, using a small, low-power, and fast reading NAND flash memory, combined with a high-performance processor microcontroller, can achieve high-speed data access.Through calculating its theoretical storage value,removing the influence of bad blocks, the storage capacity can be increased by more than three times compared to before optimization. Data reading, writing, and erasing can be significantly improved too, and it has non volatility due to power failure. This product can record real-time data such as triaxial vibration, pressure, rotational speed, and stickiness during the drilling process, which helps to understand the situation of downhole drilling operations, optimize parameters, analyze wellbore instability and drilling tool failure, improve drilling efficiency, reduce well construction costs, and provide important reference basis for intelligent drilling operations.
