An Efficient Lossless Compression Algorithm for Well Logging Result Drawings

Since the data of Well Logging Result Drawings is so large, it is necessary to apply efficient algorithm to compress them. Based on the lossless compression of LZMA (Lempel-Ziv-Markov chain-Algorithm), this paper presents a new compressing algorithm for Well Logging Result Drawings after analyzing Result Drawings in CGM (Computer Graphics Metafile) format. The experiment results indicate that the compression ratio of the proposed new algorithm for the Result Drawings with cgm format is larger than currently popular compression software. The new algorithm is also suitable to compress Result Drawings in any other vector format.
