受边界断裂和滨县凸起的控制,滨南油田北部边缘下第三系发育了冲积扇、扇三角洲和浊积扇等不同成因的砂砾岩扇体。文中对砂砾岩扇体的沉积类型及相应的地震相进行了研究,建立了砂砾岩扇体的沉积模式及地震识别模式,并总结了砂砾岩扇体的空间展布规律以及成藏类型和规律。油气勘探实践证明上述规律和研究方法经济有效。

Controlled by boundary faults and the Binxian Uplift, sandy-conglomeratic fans of different geneses such as alluvial fans, fan deltas and turbidite fans were developed in the Lower Tertiary on the northern margin of Binnan oilfield. In this paper, the sedimentary types and corresponding seismic facies of sandy-conglomeratic fans were studied, their sedimentation pattern and seismic recognition pattern were established, and their spatial distribution regularities as well as pool-forming types and rules were summarized. The practice of oil and gas exploration showed that the rules and research methods above are economically effective.
