Real-Time Compression and Edge Computing Processing Method for Dynamic Monitoring Data of Reservoir Development
摘要
The exponential growth of dynamic monitoring data for reservoir development poses critical challenges, including transmission bandwidth, storage pressure, and latency. To solve these problems, a novel adaptive compression algorithm based on temporal and spatial correlation is introduced. A modified ARMA model based on time-series analysis is uniquely combined with the improved Kriging interpolation method to describe spatial correlation. A hybrid coding strategy based on Huffman-arithmetic has been proposed to reduce redundancy while preserving data fidelity. Superior performance was demonstrated by experimental validation using 6-month pressure, temperature, and flow data (1-min sampling interval). Compared with Huffman encoding (18.2), LZW coding (15.8), and wavelet transform (25.3), respectively, the average compression ratio was 32.6%. Notably, it maintains an average absolute error of only 0.023, representing a 35.3–62.3% reduction compared to benchmark methods. Processing of edge nodes (0.8 ms compression time) and data transfer (12 ms delay) meet real-time operation requirements. It provides a transformative solution to efficiently transmit and analyze reservoir monitoring data, which will have an impact on enhanced decision-making in the field.
