摘要 

陆相储层稠油热采时移地震监测数据开展的互均衡处理结果表明,此项处理有利于有效时移地震异常的识别与热前缘位置的准确确定。当原始采集资料的一致性极差时,互均衡处理虽然可以改善资料的一致性,因此,提高野外采集震源子波和采集资料的一致性,是陆相薄互层油藏时移地震监测顺利实施的关键。振幅属性是陆相薄储层油藏时移地震监测的主要标志之一,笔者在振幅处理方面做了一些探索,取得一定效果。

Abstract

Till now, time-lapse seismic monitoring of continental thin-interbedding reservoir has not made a remarkable breakthrough, and hence the strengthening of the study and application of the time-lapse seismic method as well as the cross-equalization processing technique is of great significance. As a most effective method for improving the repeatability of time-lapse seismic data, the cross-equalization processing technique has been widely used with excellent results achieved. Through the cross-equalization processing of time-lapse seismic monitoring data obtained in the development of continental heavy oil thin-interbedding reservoir with the use of thermal recovery, it is shown that the cross-equalization processing is helpful to recognizing time-lapse seismic anomaly and determining the position of thermal front. Nevertheless, when the repeatability of original seismic data is very bad, such a processing can only improve the repeatability of time-lapse seismic data, but with no good seismic anomaly detected. The key to the successful performance of time-lapse seismic monitoring for the continental thin-interbedding reservoir is the enhancement of the repeatability of seismic wavelets and seismic data. The amplitude attribute seems to be one of the major criteria for the thinner reservoir.
