摘要

阵列声波测井是目前一种重要的测井方法。但由于它产生的数据量较大

加之电缆传输速度的限制

测井效率会因此受到影响。为提升测井效率

有必要对原始声波测井数据进行压缩处理。通过分析声波信号的特点

提出了采用DCT+适当量化+算术编码的压缩方法

并根据实际波形的测试结果对压缩方法进行了一系列改进。通过对660组真实测井数据的测试

得到了对于672个点的单极声波数据平均4.56的压缩比

对于1 200个点的偶极声波数据平均9.18的压缩比

均方根误差在2%左右

证实了该方法的有效性。

Abstract

Array acoustic logging is one of the most important logging methods presently. However

due to its huge amounts of data and the speed limit of data transmission

logging efficiency is restricted. Data compression and processing is necessary to improve logging efficiency. By analyzing characters of acoustic signal

introduce a compression method comprised of DCT

proper quantization and arithmetic coding

further

a series of improvements are made to the method. By test on 660 group real logging data

it is proved that the method is effective

average compression ratio（ CR） is 4. 56 to the monopole acoustic data of 672 points and 9. 18 to dipole acoustic data to1200 points

with root-mean-square error around 2 %.
