| 摘 要： | 红车断裂带中断裂十分发育，体系复杂，且主断裂延伸长，空间上不同部位断裂特征及控藏作用差异明显.利用测井、岩心、高精度地震数据体资料，根据断裂性质、组合样式及活动强度差异性等在平面上将红车断裂分为南北两段，北段主要发育逆断裂，南段主要发育走滑断裂；在剖面上分为上下两层断裂体系，上层为张性断裂体系，下层为压性断裂体系.红车断裂带深部断裂结构发育，成岩胶结作用强.对流体包裹体及裂缝胶结程度研究表明，红车断裂深部早期封闭性较差，但随成岩胶结作用进行，北段封闭性逐渐变好.断裂带浅部为砂泥岩互层，断裂结构不发育.利用断层泥比率、断裂带泥质含量、断面正应力及紧闭指数评价其封闭性，显示浅部封闭性在不同时期变化较大：白垩纪早期南段好于北段，古近纪中晚期—新近纪早期北段好于南段.红车断裂带北段油气比南段更为丰富，在北段为阶梯状成藏模式，南段为“花状”成藏模式.

| Abstract: | Fractures in the Hongche fault belt are highly developed with complex system and a long extension of major fault. There are obvious differences in the fault characteristics and reservoir-forming control in different spatial parts. Based on the logging, core and high-precision 3D seismic data, according to the differences in fault property, combination style and activity intensity, the Hongche fault belt, in plane view, can be divided into two segments of north and south which are dominated by reverse and strike-slip faults respectively; while in profile, divided into upper extension and lower compression fault systems. The fault structure is developed in deep with strong cementation. The study on the fluid inclusions and cementation degree of fractures indicate that the sealing capacity of deep fault is poor in the early stage, yet that in the north getting better with the cementation process. The fracture is undeveloped in the sand-mudstone interbedded shallow part of the fault belt. The results of SGR, Rm, F and IFT suggest that the sealing of shallow part vary greatly in different periods. Specifically, the sealing of north segment is better than that of south in Early Cretaceous, while the case is the opposite during Middle and Late Paleogene-Early Neogene. The reservoir in the north is more abundant than that in the south, corresponding to ladder-like and flowerlike accumulation models separately. |
