中文摘要:
      文章主要讨论了通过测量超声纵波、横波在地层岩心中的传播速度获取地层岩心弹性力学参数、确定地层岩心主应力方向的原理和方法,并通过对胜利油田五个区块、不同井深地层岩心的实际测量,结合地磁定向,给出了相应岩心主应力相对于地理北极的方向。
英文摘要:
      The principle and method for determining elasticity mechanics parameters and main stress direction of stratum rock using velocity of longitudinal and transverse ultrasonic waves are introduced.Stratum rocks in five different areas and at different depths in Shengli Oil Field are measured.Taking into account the direction confirmed by using a geomagnetic method, the main stress direction of stratum rock with respect to the directions of the geographic poles is obtained.
