井地地震CT技术及其应用
|
摘要
井地地震是在井间地震方法基础上提出,其技术核心主要是观测系统设计以及数据的采集和处理。观测系统设计旨在增加探测目标的覆盖次数、均匀程度和提高工作效率;数据采集从震源和检波器两个方面优化,选用激发能量强、频率高、成本低、效率高的震源,以及灵敏度高、抗噪能力好的检波器;数据处理分为拾取初至、建立正演模型和反演层析成像。工程应用实例说明,井地地震具有很好的应用前景。
The principle and characteristic of Well-Ground seismic technology are reviewed systematically based on crosshole seismic method.Special emphasis of the technology of Well-Ground seismic is superior in imaging resolution,studying scope,wild production efficiency and production cost,ect.The data acquisition system(ob-servation system,ground seismic source and borehole seismic detector) and processing methods(ray tracing proc-essing and tomography imaging) are discussed.Then,the application areas and development of Well-Ground seis-mic technology are recommended.Finally,the development and application prospects of Well-Ground seismic technology are forecasted.
