摘要
在川西地区,裂缝是影响产能的关键,利用传统的相干研究方法很难识别出微小断层和裂缝的发育位置。地震相干体分析技术是三维地震解释及岩性分析的重要技术手段,通过倾角、方位角和相干的叠加显示,除可以识别断层外,还可以预测裂缝发育带。利用体属性相干、倾角检测和方位角分析对川西地区沙溪庙组作相干处理,证实了该区高产气井的位置处于裂缝发育带上。
Fractures are vital to the production capacity in western Sichuan.Compared to traditional coherence analysis,seismic coherence cube provides more detailed information of faults and fracture development belts through the superposition display of dip angle,azimuth,and coherence.In this paper,the author applied coherence cube to Shaximiao Formation,and verified that all existing high-yield wells are located in fracture development belts.
