摘要
利用地震、测井及录井资料,恢复古近系沙河街组三段沉积时期莱州湾凹陷构造-古地貌特征,分析构造-古地貌对沉积体系的控制作用。沙三段沉积时期,莱州湾凹陷可划分为8个构造-古地貌单元,包括东部断坡带、东北斜坡带、北部斜坡带、西部斜坡带、南部斜坡带、中央凸起带、北部洼陷带和南部洼陷带,西部和南部斜坡带存在明显沟谷。受构造-古地貌控制,沙三段沉积时期莱州湾凹陷的东部发育扇三角洲,西部和南部发育辫状河三角洲,三角洲沉积体系的主体发育部位明显受次洼的控制。受东部断坡控制形成的扇三角洲砂体,受西部和南部缓坡及沟谷控制形成的辫状河三角洲砂体,特别是受西部缓坡控制在北部洼陷发育的大型辫状河三角洲砂体,是油气勘探的重要目标。
Based on seismic and logging data,the characteristics of tectonic-paleogeomorphology of the Laizhouwan sag during the sedimentation of the Paleogene Shahejie Formation Sha 3 member(E2s3) were restored and the control of tectonic-paleogeomorphology on sedimentary systems was analyzed.During the sedimentation of E2s3,the Laizhouwan sag can be divided into eight tectonic units,including the eastern fault-slope zone,northeastern slope,northern slope zone,western slope zone,southern slope zone,central uplift belt,northern sub-sag and southern sub-sag;gullies occur in the western and southern slope zones.Controlled by the tectonic-paleogeomorphology,the fan delta was developed in the eastern Laizhouwan sag and the braided river delta was formed in the south and west of the Laizhouwan sag in the sedimentary period of E2s3,and the developmental place of the main part of the deltaic depositional system was significantly controlled by sub-sags.The fan delta sand body,controlled by the Eastern fault ramp,the braided river delta sand body controlled by the Western and Southern gentle slopes and the gullies,and especially the large braided river delta sand body in the northern sag controlled by the western gentle slope,are important exploration targets for oil and gas.
