碳酸盐岩裂缝性气层检测方法探索

Probing on the Method of Detecting Fractured Carbonate Gas Zones

本文从裂缝性储层的地质特征分析了裂缝性气层地震响应的特点,指出检测这类气层需用三维空间追踪。通过合成地震记录分析,明确了需用高频地震资料检测气层。文中还讨论了高分辨采集和处理中的问题和方法,最后提出用“高、低频振幅差检测气层(HML)法”的新思路。

According to the geological characteristics of the fractured reservoirs, the authors analyze the seismic response properties of fractured gas zones and point out that the three-dimensional space traee is needed fer detecting such gas zones. Through analyzing the synthetic seismograms, it is clear that the gas zones can be detected by use of high frequency seismic data. The problems and methods of high-resolution acquisition and processing are also discussed in this paper, and a new thought of using 'the method of'High-frequency Amplitude Minus Low-frequency Amplitude (HML)' to detect gas zones' is proposed in the last of this article.
