测井成果图压缩软件的设计与实现

Design and Implementation of the Compression Software for Well Logging Results

随着测井新技术的发展,测井成果图数据越来越庞大,给计算机系统的存储、网络传输和应用都带来了很多问题。因此,对成果图像进行高倍压缩,减少所占的存储空间,提高网络传输的速度,是非常必要的。本文从分析成果图的格式入手,提取了图像特征,给出了数据预处理方法,基于字典压缩提出了一种高效的数据压缩方法。以上方法都通过C++语言完成了软件实现,并已在生产中应用。

With the development of new logging technology, the amount of well logging data is becoming larger and larger, which has brought many problems in the storage, transmission and application of computer system. Therefore, it is necessary to compress the images to reduce the storage space and improve the speed of network transmission. In this paper, the image features are extracted from the format of the analysis results and the data preprocessing method is presented. An efficient data compression method is proposed based on dictionary compression. The methods are complished by C++ language and have been used in production.
