摘要

渤海莱州湾凹陷南部古近系沙三下亚段广泛发育陆源碎屑与碳酸盐混合沉积。通过对井壁取心、测井及综合化验资料的分析,对研究区混合沉积特征、发育模式及控制因素进行分析。结果表明: 研究区既发育同一岩层内的混合沉积,又发育碳酸盐岩与陆源碎屑的互层混合沉积。混合沉积形成于两大物源注入背景下的湖泊滨岸环境,可进一步分为泥坪、砂质滩坝、浅滩和半深湖等混合沉积亚相,主要体现为波浪和湖流作用的双重影响。沙三下亚段整体呈现出水退式发育的特点,主要发育湖侵域和高位域,湖侵域主要发育半深湖混合沉积和浅滩混合沉积,高位域主要发育砂质滩坝混合沉积。混合沉积物受古地貌、古气候、古物源和湖平面变化的控制,优势储集亚相为砂质滩坝混合沉积亚相和浅滩混合沉积亚相。该研究成果不仅为莱州湾凹陷南部古近系优质动用储量研究提供了指导,而且为下一步勘探指明了方向。

Abstract：

Mixed clastic-carbonate deposits were widely distributed in the Lower part of Paleogene E₂s₃ Formation,Laizhou Bay sag,Bohai Sea. This paper studied the characteristics,facies and development model of the mixed deposits in this area based on sidewall coring,well logging data and laboratory sample analysis.Results show that the characteristics of deposits were mixing deposited between terrigenous fragments and carbonate constituent in one layer, and interbedded strata between terrigenous fragment and carbonate in the study area. Mixed rocks developed in lacustrine shore zone with input from two large provenances,and can be further classified into the following types: Mud flat subfacies of mixed deposits,sandy beach-bar subfacies of mixed deposits,shoal subfacies of mixed deposits, and semi-deep lake subfacies of mixed deposits. The mixed deposits were both controlled by wave actions and lake currents. According to the seismic,drilling,logging and paleontology data,it showed a regressive sequence feature for the lower part of the E₂s₃ Formation which contains lacustrine transgressive system tract(mainly includes mud flat subfacies of mixed deposits and sandstone bank subfacies of mixed deposits)and high-stand system tract(mainly includes bar subfacies of mixed deposits). The mixed deposits were controlled by palaeogeomorphology,palaeoclimate,palaeosource and lake level changes. The study showed that sandy beach-bar subfacies of mixed deposits and shoal subfacies of mixed deposits are dominant facies belts providing implications for researches on high-quality development reserves and direction of further exploration.
