通过对C20块蒸汽驱试验区地震监测野外采集方法和室内处理技术的研究,以及监测地震资料在油气开发中的解释应用,分析了地震监测的野外观测系统及施工工艺方法,采用了特殊的资料处理流程和处理参数等四维地震资料处理手段,成功地监测到了注入蒸汽的波及前缘成像,指出了注入蒸汽在河流相地层的运移规律。

The authors conducted researches on the field acquisition methods and inhouse processing techniques of seismic monitoring in the vapour flooding testing area of the C20 block. By analyzing the field observation system and working technology, as well as adopting special data processing flow and parameters, the authors have monitored the involving front image of injected vapour, pointed out the law of injected vapour migration in river facies strata, and determined the draining thick oil area and residual oil area.
