| 摘 要： | 交叉偶极子声波测井可以实现常规声波测井无法实现的对软地层的横波测井。利用交叉偶极子声波测井资料,可分析由裂缝和不均衡地应力等引起的地层各向异性,通过分离出的快、慢横波的时差和波至时间,计算出地层各向异性系数,评价地层各向异性;还可以利用斯通利波估计裂缝的张开度和评价地层的渗透性。本文介绍了哈理伯顿生产的交叉偶极子声波测井仪WSTT的基本结构和测量原理,主要用途和测井操作时的注意事项,以及在地层评价中的应用。

| Abstract: | The cross-dipole acoustic tool can achieve the shear wave logging which conventional acoustic tool can not actualize in soft formation.It uses its logging results to analyze formation anisotropy caused by fracture and unbalanced stress,and calculates the anisotropy coefficient by separating the DT and arrival time of fast shear wave and slow shear wave to evaluate formation anisotropy;it also uses Stoneley wave to estimate the stretch open extent of fracture and evaluates the permeability of formation.It introduces the specification and logging principle,usage and operation notice,application of WSTT made by Halliburton. |
