摘要/Abstract

摘要： 目前地震属性的提取主要集中在单项技术上,如谱分解、三瞬、均方根、自相关、主因子、自回归和相干体等。对提取后的属性如何根据它们自身的特点,做进一步处理以得到新的地震属性,人们尚缺乏足够的关注。借鉴信息工程有关理论,提出了叠合、差值、乘积和级联等物理含义简单、但又比较讲究数据间匹配和显示的新的地震属性——复合属性,并开发了相应的软件。利用复合属性,对LHK地区河流相储集层进行了精细解释,分辨率和信噪比得到明显提高。

关键词: 复合属性, 级联属性, 相干体, 河道解释

Abstract: The technologies for pickup of seismic attributes include generally Fourier spectral analysis, autocorrelation, main component, autoregression and coherent body, etc. However, how to get new seismic attributes from the extracted attributes is still insufficiently concerned about. This paper proposes a new seismic attribute-compound attribute and develops the corresponding software package by means of information engineering principle, which is characterized by simple physical significances such as overlay, difference, product and cascade, etc. and sensitive data match and display. The compound attribute is used for the detailed interpretation of fluvial facies reservoir in LHK area, showing that the resolution and the S/N ratio are improved obviously.

Key words: compound attribute, cascade attribute, coherent body, channel interpretation
