摘　　要：提出了用脉冲激光全息干涉法测量石油井下小尺寸岩芯的表面波速率,进而获得其动态弹性参数的方法,测量了大庆油田不同井位、不同层位3块岩芯的动态弹性参数,综合测量误差不大于5％,满足工业测量要求。This paper introduced a method to get the dynamic elastic parameters of smalldimension core by using pulse laser holography to measure the surface wave velocity of core. Thedynamic elastic parameters of three pieces of core samples that are get from different well and layersof Daqing oil- field are measured. The synthesis measuring error is less than 5% the measuringresult can meet the measuring requirement of industry.
