中文摘要：
以往研究表明煤层具有弱各向异性,为正交各向异性介质,因此利用P波的方位各向异性属性来进行煤层裂隙裂缝检测、预测煤层瓦斯富集带是行之有效的方法.本文对山西阳泉新景佛洼区的三维地震资料进行处理,得到4个方位的偏移数据体,并提取与煤层裂隙裂缝相关的多种地震属性.通过计算得到裂隙裂缝的相对密度,进而对煤层瓦斯的富集带进行预测.
英文摘要：
All of research results indicated that coal is orthogonality anisotropic medium. So it is a effective method that detect fractures and forecast the gas enriched area using seismic Pwave azimuth attributes. After 3D seismic P-wave data in Fowa mining area, Xinjing coalmine, Yangquan, are processed, and 4 azimuth migrated data cubes are obtained from which several attributes related with fractures are extracted. Then the relative fracture density is calculated and the gas enriched area is predicted.
