本文综合应用层序地层学、沉积学、石油地质学等理论和方法，通过钻井岩心观察、测井资料解释、薄片鉴定和储层岩性物性分析等手段，对文东的沉积相及砂体展布进行深入研究。 层序地层学方面研究，主要利用地层接触关系、相旋回特征和相界面、区域性特征界面最大湖泛面、河道砂体的叠置方式以及区域较好的对比标志层识别层序界面。将文东油田沙二下划分为一个构造超层序和八个三级沉积层序。利用小层对比划分原理并结合重点单井划分对比小层。 沉积相方面研究，首先研究沉积体系，借鉴前人的研究，结合对文东油田沉积环境、沉积相标志的重新认识和研究，识别出文东沙二下主要由漫湖、三角洲沉积体系组成，并进一步细分亚相及微相。 物源方面研究，沉积期存在多个物源区，即东部物源区、西部物源区、北部物源区、南部物源，具有多物源、多沉积中心的特点。其中鲁西隆起和内黄隆起是东西两大物源供给区。母岩主要有早古生代碳酸盐岩和白云岩、石炭—二叠纪含煤碎屑岩组成，少量太古代结晶变质岩和中、新生代中酸性花岗岩。近物源、洪水事件性沉积发育。 砂体方面研究，首先砂体的展布受控于沉积相的展布，呈南北方向条带状展布，同沉积断层控制着汇水体系和物源的位置，成为砂体输送通道。 总之，研究沉积及砂体展布规律为滚动勘探找岩性油气藏提供依据。

In this paper, to Wendong oil field, I have applied sequence stratigraphy, sedimentology, oil geology ,such as the theory and methods, through the observation of core drilling and interpretation of logging data and identification of core slice such as analysis of the means,and had a more in-depth studies on sedimentary facies and the distribution of sand body . First of all, on the study of sequence stratigraphy,with the strata contact relations, characteristics of the cycle of phases,phase surface, maximum lake flooding plane of the regional characteristic interface,overlain style of river sandbody and the good regional symbol , I have identified sequence boundary. Wendong oil field have been divided into a super-structure sequence and eight third-order sedimentary sequences. With the principle of comparison and contrast of sandbody ,combined with the focus of a single well, wendong oil field divided into a number of small layers. Secondly, on the study of sedimentary systems, through a new awareness of signs and research I have drawn on previous research, combined with oilfield sedimentary environment ,identified Wendong oil fied as mainly diffuse Lake, Delta depositional system components and divided into various sub-phase and microfacies types. Thirdly, on the study of sediment source, Deposition period of the existence of a number of source area, namely, is the eastern source area, the western source area, the northern source area and the southern source. The oil field have been multi-source, multi-center characteristic of sediment,in which Neihuang-Luxi uplift from the East and the West were the source of supply of the two areas. Early Paleozoic rock are mainly carbonate , dolomite, Carboniferous - Permian coal-bearing clastic rock and a small amount of Archean crystalline metamorphic rocks and Mesozoic-Cenozoic granite acid. Sedimentary of closely related source and flood events had been well developed. Fourthly, on the study of Sand body study, the distribution of sand bodies is controlled by the distribution of sedimentary facies, the direction is north-south banded distribution, syn-sedimentary fault charges water catchment system and source position as transmission channel of sand body. In short, the study of sand body deposition and distribution will provide a basis for in the progressive exploration and development on lithologic oil reservoir.
