面向油田开发的井控地震资料处理技术及应用
|
摘要
在油田开发过程中,人们对地震资料的保真保幅性、分辨率及井震资料吻合率提出了更高的要求。以塔里木盆地面向开发的三维地震资料处理项目为依托,对井控处理技术方法、思路及应用效果进行了研究,利用钻井、测井、VSP等井信息对振幅恢复处理、反褶积处理以及叠前时间、深度偏移处理等关键处理步骤进行约束,使各处理工序的关键参数选取有据可依,使处理成果数据在保幅、拓宽资料频带及偏移归位等方面更加合理,从而为油田开发提供高品质的成果资料。应用结果表明,井控处理后的地震资料在保真保幅、合理提高分辨率及井震吻合度方面均取得了较为明显的效果。
During the oilfield development,preserved-amplitude,fidelity and resolution of seismic data and consistent rate of well-seismic data has put forward higher requirements.According to the geological requirements of oilfield development,drilling data,logging,VSP well information are used to restrict the key processing steps,including amplitude recovery processing,deconvolution processing,PSTM and PSDM,which gives criteria for the selection of key parameters and makes the processing results more reasonable for amplitude-preservation,frequency broadening and migration imaging,thus provides high quality seismic data for oilfield development.The well-controlling processing of 3Dseismic data in Tarim Basin indicates that obvious effect has been obtained in amplitude-preservation,fidelity insurance,reasonable improvement of resolution and well-to-seismic accordance.
