Abstract
Disclosed is a downhole vibration and impact data recording method, comprising: performing analog-to-digital conversion on analog data, outputting digital format data obtained at a sampling rate f, and performing sampling storage processing and analysis storage processing on the same. The sampling storage processing includes outputting the digital format data obtained at a sampling rate fn through multiple samplings; storing the same continuously into a storage module. The analysis storage processing includes: buffering the digital format data obtained at the sampling rate finto a memory; analyzing the same to determine whether an impact event occurs, and if yes, storing the current data in the memory into the storage module, and then jumping back to the buffering step; otherwise, jumping directly back to the buffering step. With the above method, the amount of data storage can be effectively reduced, while the characteristics of the vibration and impact data can be analyzed.
