摘　　要：在随钻测量系统中,目前采用的主要传输技术是泥浆压力波正负脉冲的方法,该方法所固有的缺点是信号传输速率低,因此,在低信号传输速率下,研究数据的压缩技术,从而提高信号的传输效率具有非常重要的意义。提出采用Huffman技术对数据进行压缩,从而实现随钻测量系统的高效传输。实验证明:压缩比可以满足实际应用需求,具有广泛的应用意义。In the measurement while drilling system, the main transmission technology currently used is the mud pressure wave of positive and negative pulse. The demerit of which is the low signal transmission rate. Thus in the low rate of signal transmission, to study the compression technology so as to improve the transmission efficiency of the signal is of great importance. The paper proposes Huffman technology to compress the data and consequently enable the drilling with the measurement system to transfer efficiently. The experiment shows that the compression ratio can meet the needs of practical application, and has wide application significance.
