高分辨率 3D 非线性的综合倒置方法基于非线性的理论。在层控制下面,从几口井的日志数据(或所有井) 在学习区域和地震踪迹,邻近井的数据是到有多重输入和产量的一个网络的输入并且综合地被训练获得全部学习区域的一个适应重量函数。综合非线性的印射关系被水库的侧面、垂直的地质的变化造并且更新。因此,倒置过程和它的倒置结果能被抑制并且控制并且有有速度倒置,阻抗倒置,和密度倒置节的高分辨率的稳定的地震倒置节,能被获得。好地质的效果在模型计算测试并且真实数据处理被获得了,它证实这个方法让高精确,好实物,和罐头被用于量的水库分析。
The high resolution 3D nonlinear integrated inversion method is based on nonlinear theory. Under layer control, the log data from several wells (or all wells) in the study area and seismic trace data adjacent to the wells are input to a network with multiple inputs and outputs and are integratedly trained to obtain an adaptive weight function of the entire study area. Integrated nonlinear mapping relationships are built and updated by the lateral and vertical geologic variations of the reservoirs. Therefore, the inversion process and its inversion results can be constrained and controlled and a stable seismic inversion section with high resolution with velocity inversion, impedance inversion, and density inversion sections, can be gained. Good geologic effects have been obtained in model computation tests and real data processing, which verified that this method has high precision, good practicality, and can be used for quantitative reservoir analysis.
