东营凹陷北带东段沙四上亚段地震沉积学研究
|
摘要
为了探讨深层砂砾岩体地震沉积学研究方法,在地质规律和地震沉积学理论指导下,以岩心、测井和录井资料为约束,利用90°相位转换,地层切片技术对东营凹陷北带东段沙四上亚段各四级层序进行地震沉积学研究。建立了深层砂砾岩体地震沉积学研究流程,明确了研究区发育的沉积相类型,分析了各沉积相类型分布与演化特征。研究表明:地震沉积学关键技术对深层砂砾岩体具有适用性,在井间沉积相研究中具有明显优势;沙四上亚段为完整的三级层序,分为5个四级层序;沙四上亚段时期,东营凹陷北带东段发育近岸水下扇相、滑塌浊积扇相、湖泊相3种沉积相类型,其中,近岸水下扇沉积近陈南断层分布,纵向上退积发育。
To research the approaches of seismic sedimentology on deep glutenite bodies were discussed,guided by geological laws and seismic sedimentology theory,and constrained by core and logging data,fourth-order sequences of the upper Es_4 in the eastern section of northern zone of Dongying sag were analyzed by using 90°phase shift and stratal slicing technology. The research procedure for deep glutenite bodies was established. The sedimentary facies types were confirmed and their distribution and evolution were analyzed. The results show that the key technologies of seismic sedimentology are suitable for interpretations of deep glutenite bodies and have significant advantages in interwell sedimentary facies. The upper Es_4 has a complete third-order sequence. It can be divided into 5 fourth-order sequences. In the sedimentary period of upper Es_4,nearshore subaqueous fan,slump turbidite fan,and lacustrine sedimentary facies were developed in the eastern section of northern zone of Dongying sag. The nearshore subaqueous fans were distributed near the Chennan Fault and the retrogradation depositional system was well developed in the vertical direction.
