| 摘 要： | 以塔里木盆地为例,探讨高分辨率电成像测井资料在裂缝成因分析中的应用。根据电成像测井图像解释,利用裂缝图像的颜色(或灰度)和产状特征,结合岩芯标定和常规测井资料,可以有效地区分构造裂缝与非构造裂缝、张裂缝与剪裂缝,确定裂缝充填与否和充填物的成分,以及裂缝的溶蚀改造程度。利用从电成像测井图像上提取的共轭裂缝的产状信息,还可以恢复裂缝形成时古构造应力场的方向。 |

| Abstract: | High resolution borehole micro resistivity image logs (FMI) were used to investigate the origin of fracture structures, with Tarim basin in northwest China as an example. The result demonstrates that structural fractures and non-structural fractures (such as weathered fractures and fractures related to collapse of paleo-caves), extensional fractures and shear fractures, and the filling and solution characteristics of fractures can be differentiated with the help of borehole electric images combined with core calibration and interpretation of traditional well log curves. In addition, the attitudes of conjunctive fractures deduced from the borehole images provide important information for the direction of paleo-structural stress field. |
| Keywords: | borehole micro resistivity image logs fracture structure origin analysis paleostructural stress field Tarim Basin |
