| 摘 要： | 为改善储层目标区域的成像质量,结合地面地震、VSP和井间地震的各自优势,采用归一化后的自适应叠加方法,实现3种资料偏移结果的联合成像,以达到各种资料优势互补、提高成像精度的目的。为了给联合成像提供精度较高的单种资料成像剖面,采用傅里叶有限差分叠前深度偏移算法实现地面地震资料成像;在VSP和井间地震资料的叠前成像中采用了基于起伏地表直接下延法成像思想,基于傅里叶有限差分延拓算子得到VSP和井间地震偏移结果。模型试算和实际资料的处理验证了多尺度地震资料联合成像法的正确性和有效性。

| Abstract: | In order to improve the imaging quality of target reservoir area,combining the advantages of surface seismic,VSP and cross-well data,we adopt a method which is called normalized and adaptive stack to realize the joint imaging of these three migration results.Therefore,they can be complementary with each other and enhance the precision of imaging.For the purpose of offering high precision single imaging profile to joint migration,we get surface seismic migration result by Fourier finite difference pre-stack ... |
