渤海湾盆地QHD29-2区块东营组东三段沉积与构造-古地貌的响应
|
摘要
QHD29-2区块南侧石臼坨凸起的控边断层具有中部活动强、两侧逐渐减弱的构造活动特征,造就出中部陡、两侧缓的构造-古地貌格局,并对沉积体系发育的类型、沉积充填序列具有明显的控制作用。基于单井相、概率累积曲线、C-M图、薄片分析和地震多属性分析的综合研究,结果表明,研究区东营组东三段沉积相模式与中部陡、两侧缓的构造-古地貌格局具有良好的响应关系,中部构造活动强的陡坡带,发育平面呈扇形、朵形的近源快速堆积的扇三角洲沉积,两侧构造活动弱的缓坡带,发育平面呈条带状的长距离搬运后沉积的辫状河三角洲。
The Shijiutuo Uplift,which is located in the southern part of the Block QHD29-2 in the Bohai Bay Basin,is bounded by faults which controlled not only the boundaries of the uplift,but also the paleogeomorphic pattern characterized by a steep horst in the center and flat slopes outwards.Faulting was intensive at the center and gradually became weaker to the out sides.The structural pattern was obviously the main factor which controls the types of depositional system and the filling sequences.Integrated study has been carried out for well logging facies,cumulative probability curve,CM diagram,thin sections and seismic multi-attributes.Results show that the distribution pattern of sedimentary facies of the Ed3 of the Dongying Formation in the study area is consistent with the paleogeomorphic features of a steep center surrounded by flat sides.The fan-shaped or flower-shaped fan deltaic deposits are distributed around the steep slope of the central uplift where occurred intensive tectonic activity and rapid and near-source deposition,whereas the braided river deltas,which were in a zonal pattern,are distributed on both sides of the steep uplift,where the tectonic activity was weak.
