Dongying depression is a Eogene down-fault lake basin. There are a series of subaqueous alluvial fans along the steep slope belt of its northern margin. This paper studies the sedimentary facies of the fan bodies in four parts of the north belt mentioned above, gives the details of the sedimentary facies features, the identifications of the fans in these areas and deals preliminarily with their forming conditions. Practice has shown that a variety of stratig-raphical and lithologic oil-gas pools of commercial value are often formed in different facies zones in the fan bodies, which are located in the downthrow of the boundary growth faults. Therefore, searching for the subaqueous alluvial fans has a practical significance for enlarging oil-gas exploration fields in eastern China down-fault lake basins.

东营凹陷为下第三系断陷湖盆,它的北部边缘陡坡地带分布着一系列水下冲积扇。本文对其中四个地区的扇体进行了沉积相的研究,阐明了该区水下冲积扇的沉积相特征及其识别标志,并初步探讨了它们的形成条件。实践表明,在边界同生断层下降盘一侧,扇体的不同相带中,常可形成具有工业价值的多种类型的地层岩性油气藏,因而,寻找这类水下冲积扇,对于我国东部断陷湖盆,扩大油气勘探领域,具有重要的现实意义。

The Miyang depression is a fault-depression lake basin holding continental deposits of Tertiary age. Though covering an area of only 1,000 square kilometers, the basin is rich in oil. The updip lithologic pinch-out pool formed of Shuanghe subaqueous alluvial fan is well-developed in the 3rd member of Hetaoyuan formation in the southern part of the depression. This alluvial fan is characterized by: (1) predominance of coarse clastics of poor sorting, with frequent occurrence of massive and graded bedding; (2) predominance of composite rhythmic sedimentation of flood turbidity flow, with grain sizes typical of the flow; (3) a fanlike planar distribution of deposits, posing as a wedge in the section; (4) a subdivision of three subfacies zones in the top, middle and bottom parts of the fan; (5) the occurrence of subaqueous channel turbidites at the top of the fan and (6) apparent reflection of the fan on the seismic profiles. The pool is mainly reservoired in the top and middle parts of the fan.

Both seismic and lithologic characteristics of BZ28—1 buried subwa- ter alluvial fan are quite distinct.There exist continuous reflections in front and above of the buried alluvial fan;on the top of the alluvial fan,there is overlap phenomenon;inside the fan,there is almost no reflection;and on its bottom boundary,strong reflections occur.Gravel is the dominant sediment in the proximal alluvial fan,sandstone in the middle fan,and sand-shale interbedding in the front fan.Drilling has shown that good source bed,reservoir bed and sealing bed exist in the alluvial fan,A comprehensive analysis of different seismic informa- tions of this fan can help us locate the hydrocarbon bearing interval, where seismic velocity and frequency decrease,and where the ratio of bandwidth energy to 10 Hz bandwidth energy increases and the hydrocar- bon content increases regularly.

BZ28—1水下沉积扇体的地震反射特征和岩相特征都比较清楚。扇体的前方和上方是连续的反射,扇体项面有超覆现象,扇体内部反射稀少,扇体底界有一组强反射。扇根部位的沉积以砾岩为主,扇体中部为砂岩,扇前缘为砂泥岩互层。钻井证实,此扇体具备良好的生储盖条件。综合多种地震信息可预测此扇体上的含油气聚集部位。在含油气部位上,速度和频率偏低,带宽能量和10Hz 能量百分比升高,碳氢指数有规律的增大。
