塔里木盆地富满油田超深海相碳酸盐岩油气资源丰富。受埋藏深度大、构造活动强的影响，其碳酸盐岩有利储层难以预测，严重制约富满油田的勘探开发。该文利用地震资料、测录井及试油资料，明确了走滑断裂纵向分层、平面分段的特征，结合走滑断裂破碎带的结构，探讨了不同特征走滑断裂带下有利储层的发育位置。研究表明：压扭段断裂有利储层发育在主干断裂中部；张扭段断裂有利储层位于两条主干断裂之间垂向断距较大一侧；走滑平移段断裂有利储层位于整个主干断裂带；复合段断裂有利储层为主干断裂附近垂向断距较大一侧。勘探结果证实，四种类型走滑断裂有利储层的发育位置与研究结果一致。该研究对富满油田碳酸盐岩有利储层的预测和井位部署具有借鉴意义。

The ultra-deep marine carbonate reservoir in Tarim Basin is rich in oil and gas. Affected by deep burial depth and intense tectonic activities, it is difficult to predict favorable carbonate reservoirs. This seriously restricts the exploration and development of Fuman Oilfield. On the use of seismic, logging and oil testing data, this paper clarifies the characteristics of vertical stratification and plane segmentation of strike-slip faults. Combined with the structure of strike-slip fault fracture zone, the development position of the favorable reservoir under the strike-slip fracture zone with different characteristics is studied. The study shows that the favorable reservoir in the compression-torsion section fault is mainly developed in the middle of the main fault; the favorable reservoir of tension-torsion section fault is located on the side with large vertical fault distance between two main faults; the favorable reservoir of the strike-slip translation section fault is mainly developed in the whole main fault zone; the favorable reservoir in the composite section fault is developed near the main fault with larger vertical fault distance. The exploration results show that the favorable reservoir locations of four types of strike-slip faults are consistent with the study. This study provides reference for favorable carbonate reservoir predicition and well location deployment.
