l偶极技术可使我们在软地层中像在硬地层中一样测取偶极技术可使我们在软地层中像在硬地层中一样测取地层的横波。由于受到井眼、地层物理特性的限制，地层的横波。由于受到井眼、地层物理特性的限制，单极声波测井仪只能在声波传播速度大于井眼流体传单极声波测井仪只能在声波传播速度大于井眼流体传播速度的地层（即硬地层）中测取横波速度，但偶极播速度的地层（即硬地层）中测取横波速度，但偶极横波成像仪克服了这一缺点，在软地层中同样可以测横波成像仪克服了这一缺点，在软地层中同样可以测取横波速度。取横波速度。l偶极横波成像仪把新一代的偶极技术与最新发展的单偶极横波成像仪把新一代的偶极技术与最新发展的单极技术结合在一起，从而提供了当今测量地层纵波、极技术结合在一起，从而提供了当今测量地层纵波、横波和斯通利波的最好方法横波和斯通利波的最好方法

CDLCDipole声波声波l使用偶极声源，这种声源是一种定使用偶极声源，这种声源是一种定向的压力源，由两个相位相反且耦向的压力源，由两个相位相反且耦合在一起的单极声源组成。这种压合在一起的单极声源组成。这种压力源可使井壁产生小的弯曲，因而力源可使井壁产生小的弯曲，因而能在地层中激发弯曲波或挠曲波，能在地层中激发弯曲波或挠曲波，它是一种频散现象很强的波，当频它是一种频散现象很强的波，当频率很低时，其速度接近于横波速度，率很低时，其速度接近于横波速度，故可在软地层用来代替横波速度。故可在软地层用来代替横波速度。CDLCl偶极声波测井仪使用了具有方向性偶极声波测井仪使用了具有方向性的发射器和接收器。偶极发射器很的发射器和接收器。偶极发射器很像一个活塞，它使井眼一侧的压力像一个活塞，它使井眼一侧的压力增加，而使另一侧的压力减小，引增加，而使另一侧的压力减小，引起井壁出现小的扰动；起井壁出现小的扰动；l这样就在地层中直接激发出纵波和这样就在地层中直接激发出纵波和横波横波
