There are some kinds of gas source rocks, i.e. biologic limestone, black mudstone and coal in Taiyuan group of lower Permian in east part of Ordos basin. In there three gas source rocks, organic substance being mainly composed of humic material-sapropel and humic material have high organic carbon content, high extent of thermal evolvement and high potential of generating gas. It provides enough gas for forming of gas reservoir in Taiyuan group. The sandstone in north and limestone in south being the major places where gas accumulate, plus billabong in deltaicplain separating river channel and mudstone in swamps environment together constitutes the combination of self generation-self reserve-upper caprocks. Under control of sedimentary facies and trip of geologic conformation, we can find some massive lithologic trap in middle and westward of research area, meanwhile, we should also focus on finding small anticlinal trap in south, north and east of research area.
Key words: Ordos basin; East; Taiyuan group; Gas source rocks; Gas generation; Reserve.
