二维地震勘探在新安县城东南部煤预查工作中的应用
|
摘要
二维地震勘探在煤田地质勘查工作中对于了解地质构造特征及推断煤层位置是较为经济有效的手段,选择合理的野外工作方法和数据采集方法是取得二维地震数据的关键,对折射波进行静校正、噪音压制、振幅补偿,采用地表一致性反褶积、子波整形、多道统计脉冲反褶积等方法手段进行数据处理,结合对钻探工程进行的数字测井,在取得准确的地层岩性声速参数后,对二维地震数据进行二次解释,基本能够准确推断煤层埋深及分布情况,为进一步钻探验证工作提供更准确的指导。
In coal field geological exploration,2-D seismic exploration was a valid and economical means to investigate the geological structure and infer location of coal seam.Proper selection of field work and data collection methods was the key to obtain the 2-D seismic data.Through refraction static correction,noise suppression,amplitude compensation,using data processing methods including surface-consistent deconvolution,wavelet shaping,ensemble deconvolution and so on,combined with digital logging of drilling engineering,precise sonic parameters of formation lithology was obtained.By secondary interpretation of 2-D seismic data,a general prediction of coal seam burial depth and distribution was obtained and an accurate guidance for further drilling verification was provided.
