井间地震波传播规律研究及应用
|
摘要
井间地震与地面地震的激发/接收方式不同,其波场特征和波场成分在地下介质中均存在差异。本文介绍其基本原理并提供了模拟垦71区块产生的波场快照、单炮记录、频谱响应、极性、叠加及偏移剖面,分析了薄互层油气储集体井间地震弹性波场特征,为分析研究井间地震的施工打下了良好的基础。
The crosshole seismic is different from the ground seismic on the type of shooting and/or receiving,so there are differences between their wavefield characteristic and components in the underground media.In this paper,the elastic wavefield characteristic of crosshole seismic of oil and gas reservoir in thinner alternating beds is analyzed by wavefield snapshots,single shot record,frequency response,polarity,stack and migration profiles from Ken 71 Block.These work lay good foundation for the the analysis and research of crosswell seismic.
