层析静校正在三维地震资料再处理中的应用及效果
|
摘要
对以往三维地震勘探原始资料进行连片处理是目前煤矿采区地震勘探中正在兴起的新方向.连片处理中,由于地形起伏大,低速带速度和厚度纵横向变化剧烈,常规静校正存在着较大局限性.因此,如何拼接地震数据,达到理想的地质效果是关键.应用层析静校正对山西郑庄煤矿三个区块的三维地震勘探原始数据进行重新连片处理,区块之间实现无缝拼接,初至波光滑,煤层反射波连续性好.利用连片处理后的数据体对以往解释成果进行修改,收到令人满意的地质效果.
Block-jointed processing technology for previous 3D seismic data is a new direction of the seismic exploration in coal mining area.In block-jointed processing,since undulation terrain,large variations of velocity and thickness,both vertical and horizontal direction,in low velocity zone,the routine static correction is large limited.So,how to integrate seismic date together is a key for reaching ideal geological effect.In this paper,3D seismic data of 3 blocks in Zhengzhuang coal mine are reprocessed by tomographic static correction technology,in which 3 blocks are seamlessly jointed together.In the reprocessing data cub,first arrivals are smooth and coal reflections are continuously traced.Previous interpretation result is revised,and geological effect is satisfactory.
