Abstract:The No.2 fault of Yitong graben is an important fault of Yitong graben,which is divided into Luxian fault depression and Chaluhe fault depression,both sides of fault developed two important hydrocarbon-bearing structural zones: Liangjia and Wuxing hydrocarbon-bearing structural zones.After fine interpretation of high-quality of 3-D seismic data,the paper studied geometric feature of No.2 fault,analyzed its specially variated characters,dynamic evolution and relation to hydrocarbon accumulation and considered that the No.2 fault not only laterally cuts Yitong graben,but also plays the role of controlling basin: it connected with east-edged fault of Chaluhe fault depression eastward and its evolution experienced early tensional and torsional actions and latter press and torsional actions,which has evidently controlling role of development of structural zones on both sides,the paper also considered that the fault is an important fault of oil-source,which has controlling role of hydrocarbon accumulation.
