摘要
在地震储层预测中,对于无测井曲线的区域,给储层预测带来了很大的难度。为了解决这个问题,笔者利用不同入射角度的叠加偏移数据和地震速度,结合遗传算法从叠前地震波形上反演弹性参数,用于虚拟测井曲线构建。通过BMM地区的实际应用证明,该方法较好地解决了无井层段虚拟测井曲线重构问题,为地震储层预测提供了比较可靠的虚拟测井资料。
In the area without logging curve,the reservoir prediction will encounter very great difficulty in seismic reservoir prediction.In order to solve this problem,the authors used stack migration data and seismic velocities of different incident angles in combination with genetic algorithm from pre-stack seismic waveform inversion of elastic parameters estimation to construct the virtual log curve.Practice shows that this means can solve the problem of getting the virtual logging curve in the area without drill holes and obtaining better result.With this method,more reliable virtual log data can be provided for seismic reservoir prediction.
