【摘要】 地震数据反演地下模型参数(地震资料解释)总是存在多解性,即地震属性成果显示与地质目标并非一一对应关系。故有必要分析、研究影响地震属性应用的不确定性因素。山东赵楼煤矿煤层局部区域受沉积因素影响,煤层结构复杂,夹矸较多、厚度不稳定(煤层变薄甚至缺失),利用采区工作面形成过程中不断丰富的地质资料标定存在多解的地震属性数据,充分挖掘地震属性反映的地质信息,提高了采区三维地震勘探对煤层沉积异常范围的解释精度。更多还原

【Abstract】 There is always multi-solution obsession in reversing underground model parameters with seismic data because the seismic attributive result exploration is not one-to-one correspondence with geological goal. So it is necessary to analyzed uncertainty factors of influencing seismic attributive. Influenced by sedimentary factor,coal-seam structure is complex for much parting number and unstable thickness in local area of Zhaolou Colliery. Applying abundant geological data to demarcating seismic attributive data and mining geological information reflected by seismic attributive,exploration accuracy of 3-d seismic exploration for coal-seam sediment abnormity range was improved.更多还原
