【摘要】 四维地震技术是利用间隔一定时间采集的三维地震数据的信息差异,来分析和监测油气藏内流体变化,作为油气藏动态监测的一种手段,已有效地应用于油气藏管理中.四维地震技术的发展与应用,主要包括四维地震的原理、特点及四维地震资料野外采集、处理、解释、应用等,最后展望了四维地震的发展方向.四维地震技术是一正在发展的新技术,虽然在国外它已进入应用阶段,但在国内还处于试验和研究阶段,应该把握机遇,加强这方面的研究,以缩小与国外油气勘探开发技术应用的差距,同时也满足国内油气田勘探开发现状对技术的迫切需求.更多还原

【Abstract】 4D seismic technology is a means of analyzing and monitoring the liquid change based on information difference of 3D seismic data collected at intervals.As a dynamic monitoring method,it has been effectively used in the oil and gas reservoir management.An overview of the development and applications of 4D seismic technology is given.The principle and characteristics of 4D seismic technology and the field collection,processing,interpretation,and applications of 4D seismic technology data are explained in detail.4D seismic technology is new and has been applied abroad,but is still being tested and studied in China.Further research is in urgent need to keep up with the foreign technology development and to satisfy the urgent needs of domestic oil and gas exploration and development.更多还原
