摘要
合成地震记录是石油勘探开发中的关键技术之一,是联系地震资料和测井资料的桥梁,是构造解释和岩性储层地震解释的基础。通过合成地震记录将地质层位标定到地震剖面上,在井资料与地震资料之间建立准确的对应关系。提出一种基于合成地震记录的正演方法,应用这一方法对地震记录对比分析可以明确地震波形的地质意义,确定含油砂层空间展布,预测圈闭的有效面积。
Synthetic seismogram is one of the key technologies in oil exploration and development.It is the contact of seismic data and logging data.It is the foundation of seismic interpretation in structure and of lithologic reservoir.Through synthetic seismogram geological horizon calibrate the seismic profile can be used,and establish the corresponding relationship between seismic data and geological data.A kind forward modeling technique based on the synthetic seismogram is proposed.Using this technology the geological meaning of different seismic wave shape can be definited,clear the oil-bearing sand layer spatial distribution,forecasting distribution of effective traps.
