| 摘 要： | 从露头、钻孔岩芯、电测曲线及地震剖面入手对百色盆地进行了相分析及古流向分析,提出了盆地发育的四种沉积体系:冲积扇、河流、三角洲及湖泊。它们在空间上有一定展布规律,构成沉积体系域。它们在时间上前后相继,展现出盆地充填序列。油气及煤的聚集发生在盆地扩展期。富煤带及油气富集与扇—三角洲—湖体系域密切相关,分别位于该体系域的三角洲平原和三角洲前缘及扇砂体中。

| Abstract: | The analyses of facies and paleocurrents have been made
for Baise basin, Guangxi, based on the outcrop, drilling well core, resistivity logs and seismic sections, upon which a series of basin analytical maps have been compiled. The authors suggest that four depositional systems-alluvial fan, fluvial, delta and lacustrine were developed in this basin. Their spatial distribution is regular, constituting some depositional system tracts. The systems occur sequentially in age, indicating the sequence of basin filling. The accumulation of oil, gas and coal took place during the stage of basin expansion. Coal-rich zone and oil, gas-rich area are closely related to the tract of fan-delta and lacustrine system; the former, is located in the delta-plain of the tract, the latter, in the delta-front and fan sand bodies. |
