大庆T30井区注水时移地震监测可行性研究

迅速发展的油田强化开采时移地震监测技术已被成功地应用于稠油热采监测中，但油田注水时移地震监测，特别是陆相薄互层油藏注水监测的研究却刚刚起步，时移地震能否用于监测注水动态，可行性分析是关键，利用Lumley等人（1997）给出的时移地震监测技术风险定量评价方法，对大庆T30井区葡一组油层注水时移地震监测的可行性进行了初步分析。结果表明，在现有条件下，在大庆油田开展注水时移地震监测工作是比较困难的，至少对T30井区葡一组油层而言，这一结论基本上是可信的。

Feasibility study of time-lapse seismicmonitoring of waterflooding in Daqing well-T30 area

Time lapse seismic monitoring in enhanced recovery has achieved a rapid development in recent years, and it has been successfully used in monitoring thermal recovery of thick oil field. However, time lapse seismic monitoring of waterflooding, especially the waterflood monitoring in thin inter bedded reservoirs of land facies, is still in its infancy. Whether or not time lapse seismic method can be used to monitor waterflood performance, the key is feasibility analysis. For Pu 1 reservoir of well T30 area in Daqing, the feasibility of time lapse seismic monitoring of waterflooding is analyzed using the Lumley' quantitative assessment method(1997). The results show that it is hard to monitor waterflood performance by time-lapse seismic method in present conditions in Daqing oilfield. It is true at least for the Pu-1 reservoir of well-T30 area of Daqing.
