摘要: 时移地震是一项解决油藏动态描述的有效技术,但自20世纪取得成功以来,受高昂成本和应用范围的限制,一直以来未得到广泛的应用。2007年以来,胜利油田针对高成熟探区二次地震采集普遍化的现状,提出了非一致性时移地震的思路,针对如何评估与消除非一致观测系统的影响、如何检测开采变化的微小差异、如何综合利用时移结果等一系列技术难题,历时十余年,创新形成了非一致性时移地震观测系统匹配技术、基于井数据的叠前互均化技术、叠前叠后敏感属性联合优化技术和基于油藏数值的时移地震综合解释技术等4项关键技术。配套形成了水驱型复杂断块油藏时移地震技术、小尺度气藏边界监测时移地震技术、蒸汽吞吐型稠油油藏时移地震技术,实施了6个区块300 km2的应用示范,展示了成果的广阔前景,拓宽了油藏地球物理技术解决开发难题的能力。Abstract: Time-lapse seismic survey is an effective technique for reservoir dynamic description,but it has not been widely used since its success in the last century due to the high cost and the limitation of its application range.Since 2007,Shengli Oilfield has put forward the idea of non-uniform time-lapse seismic survey in view of the current situation of the secondary acquisition seismic survey in high mature exploration area.Aiming at tackling a series of technical problems,such as how to evaluate and eliminate the influence of non-uniform acquisition system, how to detect the small difference of monitor changes and how to comprehensively use the time-lapse results,researchers have spent more than ten years to innovate the key technologies,i.e.,the matching technology of non-uniform time-lapse seismic acquisition system,the pre-stack cross equalization technology based on well data,the joint optimization technology of pre-stack and post-stack sensitive attributes,and the comprehensive interpretation technology of time-lapse seismic based on reservoir value.The time-lapse seismic technology of water-drive complex fault block reservoir,small-scale gas reservoir boundary monitoring and steam huff and puff heavy oil reservoir has been formed.The application demonstration of six blocks with an area of 300 square kilometers has been carried out,which shows the broad prospect of the achievements and broadens the ability of reservoir geophysical technology to solve the development problems.
