摘要: 渤海海域沙一、二时期混合沉积分布广泛，而在沙三段发现较少，其沉积特征及控制因素尚不明确.以莱南斜坡带沙三下亚段为例，通过壁心、薄片、钻测井、三维地震等多种资料，对研究区混合沉积特征开展综合研究，预测混合沉积平面及垂向的分布，并探讨混合沉积发育的主控因素.研究表明，莱南斜坡带沙三下亚段发育湖相与火山喷发伴生的混合沉积，在垂向发育组分式混合和互层式混合的2类混积样式；发育混积相、辫状河三角洲、火山碎屑岩相等3类沉积相类型，其中，早期陆源碎屑影响较大，发育远岸混积泥晶滩；晚期陆源碎屑影响较弱，但波浪作用增强，发育近岸和远岸共生的混积碎屑滩.温暖湿热的古气候、相对闭塞的浅水环境、同期火山形成的营养物质为混合沉积发育提供了良好条件；西部远物源和东部近物源供给控制了混合沉积发育类型；水下古隆起控制其平面分布位置及富集程度；局部火山活动形成了特殊的混合沉积岩性及其组合.该成果不仅完善和深化了渤海海域混合沉积新认识，对在沙三段寻找类似的混合沉积提供指导，也可为研究区优质动用储量及开发井网部署研究提供参考.Abstract: Mixed sediments were widely distributed in the Bohai Sea during the first and second periods of Shahejie Formation, but few were found in the third period. In this paper, taking the lower third member of Shahejie Formation of the Lainan slope belt as an example, the mixed deposit characteristics of the study area were comprehensively studied by means of various data such as wall core, thin section, drilling log and three-dimensional seismic data, etc., the distribution of mixed deposition plane and vertical direction were predicted, and the main controlling factors of the development of mixed deposition were discussed. The results show that the mixed sediments associated with lacustrine facies and volcanic eruption are developed in the lower third member of Shahejie Formation of southern slope belt of Laizhouwan sag, and that there are two types of mixed sediments associated with fractional mixing and interbedding mixing in the vertical formation. There are three types of sedimentary facies, including mixed facies, braid delta facies and pyroclastic rocks. Among them, the early continental detritus has a great influence on the development of far-shore mixed micritic beach. The influence of land-based detritus at late stage was weak, but the wave action was enhanced, and the mixed detrital beach developed. The warm and humid paleoclimate, relatively closed shallow-water environment, and the nutrients from volcanic formation during the same period provided favorable conditions for the development of mixed deposition. The supply of far source in the west and near source in the east controlled the development types of mixed deposition. Underwater paleouplift controls its plane distribution and enrichment degree. Local volcanic activities formed special mixed sedimentary lithology and its association. The results not only improve and deepen the new understanding of mixed deposition in Bohai Sea, but also provide guidance for the search for similar mixed deposition in the third member of Shahejie Formation, and also provide reference for the study of high-quality reserve utilization and well pattern deployment in the research area.
