Abstract

A lossless compression algorithm applied on the oil well data transmission was proposed in this paper. Taylor series expansion was used to fit the curve of the oil well data, then the backward estimation was used for data processing. The lossless compression was realized by transmitting the fitting estimation error and initial sequence. From the simulation results, data compression ratio is up to 25%~40% with a low time-space complexity. Compared with other typical coding, like Huffman coding and LZW coding and Delta coding, this compression ratio has 20% advanced. Based on the verification of the actual oilfield RTU, this design can significantly decrease the burden of the data-transmitting net to 45%.
