摘　　要：红车断裂带结构特征及相关的成岩封闭作用是目前准噶尔盆地西北缘车拐地区断裂带研究中的热点,其内部结构能否准确、合理的划分对后续研究油气运移、断层封闭性等油气勘探中的关键问题具有十分的重要意义。本文综合利用野外地质露头、岩心资料,重点对红车断裂进行了详细的内部结构划分,其石炭系顶部断裂主要有北北西向、北西向、北东向和北东东向四个方向,主要发育平行式、网状、羽状、斜交式、梳式、交切式等平面组合关系,识别了红车断裂带南段发育的多条走滑断层,建立了多因素控制下断裂带内部结构发育模式。通过对断层控圈、裂缝输导、胶结封闭等方面的探讨,确立了断层对油气成藏的控制作用,为车拐地区的油气成藏及地震勘探井位部署提供了理论基础。At present,the hotspots in the fault zone research related to Cheguai area in northwestern margin of Junggar Basin are the structure characteristics of Hongche fault zone and corresponding diagenetic seals.If the internal structure of Hongche fault zone can be divided accurately and reasonably,it is of great importance to the key issues in the follow-up study of oil migration and fault sealing in oil and gas exploration.According to the data of field outcrop and core,the internal structure of Hongche Fault was divided in detail.The faults at the top of Carboniferous are mainly in four directions of NNW,NW,NE,NEE.And then the plane combination relationships are mainly developed,which are parallel,flat mesh,pinnate,oblique,comb and intersection types.It was identified multiple strike-slip faults developed in the Hongche fault zone.A development model for internal structure of fault zones was established under the control of multiple factors.Based on discussions on the control circle,crack transporting and cementing and sealing of faults,the reservoir forming control of faults was determined.So this provides a theoretical basis for oil-gas accumulation and well deployment of seismic exploration in the Cheguai area.
