基于地震反演方法的奥陶系顶部含隔水层探测
|
摘要
利用三维地震勘探成果查明奥陶系顶部的岩性分布,从一个侧面证实奥陶系顶部隔水层的存在及分布特征,并解决底板突水防治问题,这也是当前煤田地震勘探中亟待解决的问题。地震反演技术是岩性地震勘探的手段之一,把具有高纵向分辨率的已知测井资料与连续观测的地震资料联系起来,提高三维地震资料的纵、横向分辨率和对地下地质情况的勘探研究程度。应用地震反演技术对试验区三维地震资料进行分析和研究,确定奥陶系顶部含、隔水层的空间分布和厚度变化。研究成果表明,奥陶系灰岩顶部有隔水层存在,这样可为建立矿井突水的水量预测模型提供基础资料。
It is an important issue for coal seismic survey to detect lithologic distribution,to verify the existence and distribution characteristics of aquifuge in the upper portion of Ordovician system indirectly,and to solve water inrush problem on coal bottom for mining safety by utilizing 3D seismic results.Seismic inversion is one of important techniques in lithologic seismic survey.It combines both logging data with high vertical resolution and seismic data that are collected continually,improving both vertical and horizontal resolutions of 3D seismic data,and it can improve the study level of underground conditions.3D seismic data in the test area are inversed by seismic inversion;and spacing distribution and thickness variation of both aquifer and aquifuge in the upper portion of Ordovician system are also determined.Researching results show that there is a aquifuge in the upper portion of Ordovician system,and the achieved results can lay a solid foundation for the water quantity forecasting model in mining water inrush.
