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。
The method of measuring the surface wave velocity of small size core in oil well by pulse laser holographic interferometry and then obtaining its dynamic elastic parameters is proposed. The dynamic elastic parameters of three cores at different well positions and different layers in Daqing Oilfield are measured. Measurement error of not more than 5%, to meet the industrial measurement requirements.
