VSP与3D地震资料的联合处理
|
摘要
在VSP与其井旁3D地震资料在同一小区域内反射系数R（t）相同的条件下，利用VSP提取3D地震资料的子波，可实现稳定、可靠、高分辨率的子波反褶积。由于VSP走廊叠加与地质柱状剖面有良好的可对比性，使这种条件约束的子波反褶积置信度高，有利于储层描述研究，对重新利用和研究老资料很有用处，能大幅度提高分辨率而又不增加野外投资，是一项经济而又十分有效的方法技术。
On condition that the renection coefficients R(t) of VSP and near-wellbore seismic data are almost equal in a small area,wavelet deconvolution,which is stable,reliable,and high resolution,can be performed with 3D seismic wavelet cxtracted from VSP. Because of good cortelation between VSP corridor stack and geologic column section,such a wavelet deconvolution has a high confidence and is benificial to the study of teservoir description. The deconvolution is also useful in reusing and studying old seismic data. Therefore the proposed technique is cost-effective and can greatly Anprove the resolution without increasing exploration expenditure.
