多层系油气藏时移地震匹配处理技术

针对多层系油气藏开发过程中时移地震时差、相位、频率和能量累积效应所导致的处理难题,文中提出了基于多标准层的时移地震分层匹配处理技术。该技术通过选择多层系油气藏顶部、内部和底部稳定的非储层或未动用储层作为参考标准层,进行分层系匹配处理,能够有效消除多层系油气藏时移地震累积效应的影响。通过南海X油田的实际应用,取得了较好效果。

Time-lapsed seismic matching processing technology for multi-reservoir

As is known,the exploration of multi-measures reservoir will cause a lot of time-lapsed seismic matching processing problems,such as time,phase,frequency,and energy difference accumulation caused by complex changes in multi-measures reservoir production.A new method called time-lapsed seismic matching processing technology based on multi-marker horizon is proposed in the paper.By using the stable non-reservoir or undeveloped reservoir at the top and emnploying the internal part and the bottom of the multi-measures reservoir as the reference marker horizon,the time-lapsed seismic matching processing for multi-reservoir is realized,which can effectively eliminate false appearance of lower reservoir time-lapsed seismic difference caused by upper reservoir development.It was applied effectively in X oil field of South China Sea.
