鉴于弯曲模式波在井孔中传播的基本原理,制作了用于模型井孔的单/偶极子换能器,在模拟硬、软地层的铝和有机玻璃的井孔模型中进行了测量,并与理论计算的频散特性作了对比.在声速各向异性的井孔模型中进行的测试表明.弯曲模式波在横向声速各向异性的井孔中,分裂为两种传播速度不同的快、慢弯曲模式波.实验结果表明,偶极子声波测井将能有效地探测地层的横向各向异性.
In view of the basic principle that bending mode waves propagate in wellbores, single / dipole transducers for model wellbores are made and measured in wellbore models of hard and soft formations of aluminum and plexiglass, And compared with the theoretical calculation of dispersion characteristics. Testing in a well model of sound velocity anisotropy shows. Bending mode waves are split into two types of fast and slow bending modes with different propagation velocities in wellbores with transverse sound velocity anisotropy. The experimental results show that the dipole acoustic logging can effectively detect the lateral anisotropy of the formation.
