黑龙江省东部第三系盆地传递断层带特征及其石油地质意义

CHARACTERISTICS OF TRANSMISSION FAULT BELT AND ITS PETROLEUM GEOLOGICAL SIGNAFICANCE IN THE TERTIARY BASIN OF THE EAST PART OF HEILONGJIANG PROVINCE

传递断层作为拉伸盆地中的一种特有的断层类型，在盆地构造演化中协调着正断层的位置、间距和倾斜能不同所造成的矛盾，传递断层的存在对盆地所造成的分割作用在很大程度上控制了生油岩相及储集岩相的分布。在多年研究的基础上，通过综合分析，总结出黑龙江省东部第三系盆地中存在３种类型传递断层，分析了其特征及形成机理，指出了传递断层的石油地质意义，认为传递断层带是有利的油气富集带。

As a peculiar fault pattern in extensional basins, transmission fault coordinates the contradictions resulted from normal fault position, interval and different inclination energy. The basin segmented action resulted from the transmission fault controls the distributions of oil source rock facies and reservoir rock facies to a great extent. On the basis of studies for several years and through comprehensive analysis, the paper concludes three kinds of transmission fault existing in the Tertiary basin of the east part of Hielongjiang province and analyzes their characteristics and genetic mechanism. Finally the paper points out the petroleum geological signaficance of this kind of fault and regards the transmission fault belt as a favorable one of oil and gas enrichment. 
