| 摘 要： | 利用穆格莱德盆地有代表性的19口井的高分辨率六臂倾角测井处理结果，及地层产状“蝌蚪图”在断层附近的变化特征，对比过井地震剖面上的断层显示特征，探讨走滑伸展盆地背景下断层的倾角显示模式及其成因。应用彩色模式分析倾角，用一种类似常规测井曲线形态分类方法对倾角模式进行分类，将该盆地中的断层倾角模式划分为圆滑形、尖峰形、伞形、箱形、膝形、雁列形及各种形态的组合形。结果表明研究区内以圆滑形和尖峰形出现最多，膝形最少见，组合形以尖峰化的圆滑形和雁列一尖形组合为主，对各类形态所对应的断层倾角模式及沉积条件进行了探讨。

| Abstract: | On the basis of 19 representative wells of high-resoluted six-arm dipmeter processing results,the fault dip patterns variance characteristics are discussed. The tadpole plots,representing stratal dip and azimuth are compared with the seismic profiles. The color patterns are used to analyse the fault dip with a new dipmeter assorting method similar to conventional logging curve types. Based on this method,the fault dips are divided into smooth,aiguille,umbrella,box,knee,goose style in pattern,and with combinating pattern. The smooth and aiguille patterns displayed more than other patterns,the knee pattern is the least one. The combinating pattern is mainly combined by aiguilled smooth and goose style-aiguille patterns. The genesis of all these patterns and the sedimentary conditions were discussed also. |
