摘要
本研究以沉积学为理论指导,充分以研究区岩石颜色、沉积构造、结构特征、测井资料以及区域地质资料为主,来对延9进行详细的沉积微相研究,研究表明,本区延9为曲流河沉积体系,主要发育河道、天然提、河漫滩微相,其中河道是研究区主要沉积相带。本研究为绥靖油田席麻湾-白于山地区延9层的进一步勘探和开发提供了地质线索。
Based on the regional geologic background,using the rock color and texture, sedi- mentary structure, and sedimentary sequence combining with logging curves are applied to study the sedimentary microfaciesof Yah 9 in Ximawan-Baiyushan of Suijing Oilfield. The result shows that the target stratum in the study area is a suit of sinuosity rive, consisting of distributary channel, natural levee and fluviatile flood-plain, and the distributary channel sand bodies constitute the dominated reservoir, which provides geological foundationfor the further exploration and development in the target stratum.
