摘要

伊通地堑二号断层是依通地堑一条重要的断层 ,分隔鹿乡断陷及岔路河断陷 ,断层两侧发育有梁家和五星两个重要的含油气构造带。本文通过高质量的三维地震资料的精细解释 ,研究了二号断层的几何学特征 ,分析了其空间变化特征、动态演化特征及其与油气运聚关系 ,认为二号断层不仅横切伊通地堑 ,而且具有控盆作用 ,向东与岔路河断陷的东部边界断层连为一体 ,其演化经历了早期张扭作用及晚期压扭作用 ,对两侧构造带发育具有明显控制作用 ,同时认为该断层是一条重要的油源断层 ,对油气成藏有重要控制作用。
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.
