油藏监测中的时延地震技术
|
摘要
重点介绍第 6 5届EAGE年会中时延地震技术在油藏监测中的应用部分。首先 ,从数据采集、资料处理以及解释三个方面 ,概要介绍时延地震技术的新进展 ,包括采集设备的改进、震源不一致性校正、时延信号分解以及油气藏特征研究等 ;而后通过两个实例 ,展示时延地震技术在油藏动态特征监测中的最新应用成果 ,第一个实例是时延地震在油藏压力监测中的应用成果 ,第二个实例是多分量时延地震在强化采油监测中的应用成果 ;最后用少量篇幅对这次年会中的微地震技术进展进行简要介绍。
The applications of time -lapse seismic methods in reservoir monitoring are introduced in this paper, based on an analysis of the articles presented to the 65 th EAGE annual meeting. Firstly, advances in time-lapse seismic technology are briefly introduced in terms of data acquisition, processing and interpretation. The improvement of acquisition instruments and equipment, source inconsistency correction, time-lapse signal decomposition and reservoir property analysis are discussed. Secondly, two real data examples are analyzed. One is reservoir pressure monitoring by time-lapse seismic method. The other is multicomponent time -lapse seismic monitoring of a miscible CO 2 flooding. The advances in microseismicity for reservoir monitoring are also introduced.
