【摘要】 煤层气的勘探对于优化能源结构、保障煤矿安全、减少温室气体排放等具有重要意义。基于煤储层的方位各向异性和双相介质特征,方位AVO、转换横波法和AVO等地震勘探技术能够对煤层气富集区做出有效预测。测井技术具有方法种类多、分辨率高等特点,在煤层气储层识别和储层参数定量解释方面取得了较好的应用效果。开展地震技术和测井技术的综合利用是今后煤层气勘探技术的发展方向。更多还原

【Abstract】 The exploration of coal bed methane contributes greatly to optimize energy structure,guarantee coal mine safety and reduce emissions of greenhouse gases.Based on the azimuth anisotropy and two-phase medium characteristics of coal bed,azimuthal AVO,converted shear wave and AVO can detect coal bed methane enrichment area effectively.With numerous and high-resolution logging techniques,well logging technology has a good effect on reservoir recognition and reservoir parameter quantitative interpretation of coal bed methane.Comprehensive utilization of seismic technique and well logging technique is the trend of coal bed methane exploration technology.更多还原
