Abstract

Abstract: The borehole falling and hydraulic fracture during drilling have a close relation with the distribution of stress field.According to the divided feature of fast and slow shear waves traveling in the anisotropic formation,the anisotropic properties of formation and ground stress direction were indicated by the fast and slow wave information drawn from DSI data.The distribution direction of the greatest principal stress was elementarily analyzed and discussed on the basis of relationship between direction of the current greatest principal stress and distribution direction of the effective fractures in the studied area.The studied result can provide a basis for successively ensuring drilling operation and acid-fracturing treatment.

Key words: image logging, dipole shear wave, formation anisotropy, stress field, borehole, fracture distribution

摘要： 钻井过程中井眼跨塌、水力压裂裂缝的形成与应力场的分布有十分密切的关系.从不对称应力所造成的裂缝、断裂等地层各向异性属性出发,根据横波在各向异性地层中传播时所导致的分裂现象,利用偶极横波成像测井(DSI)资料所提取的快、慢横波信息来指示地层的各向异性特性及其方向.利用现今地应力方向与有效裂缝展布方向关系,对研究区现今最大主应力的方向进行了分析和讨论,该研究结果为钻井施工的顺利进行和储层改造措施的实施提供了依据.
