摘要: 通过岩心和薄片观察及测井解释等手段,以揭示饶阳凹陷中央隆起带大王庄油田沙三段上部碳酸盐岩沉积特征及沉积模式为目的开展工作,得到以下认识:饶阳凹陷中央隆起带古近系沙三段上部发育碳酸盐岩滩坝沉积,藻砂屑云岩、鲕粒云岩、泥晶云岩及含陆源碎屑的藻屑—鲕粒云岩是本区主要的岩石类型。滩坝发育四种沉积微相,包括藻屑碳酸盐岩滩微相、鲕粒碳酸盐岩滩微相、泥晶碳酸盐岩湖湾微相及含陆源碎屑的颗粒碳酸盐岩滩微相。研究区碳酸盐岩的分布主要受到湖平面变化、古地形、构造活动强度及陆源碎屑物质供应程度的影响,中央隆起带古地貌微环境的不同,直接影响到岩石类型和沉积微相的差异,高部位形成藻屑碳酸盐岩和鲕粒碳酸盐岩,低部位的低能环境形成泥晶碳酸盐岩湖湾。藻屑碳酸盐岩滩和鲕粒碳酸盐岩滩微相是本区碳酸盐岩滩坝最有利的油气储集相带。该区沉积微相的研究及相模式的建立有助于饶阳凹陷中央隆起带大王庄油田下一步精细的储层预测,也为类似地区的碳酸盐岩储层预测提供了可借鉴的地质模型。

Abstract: Carbonate rock facies model of the upper third member of Shahejie Formation of central uplift belt in Dawangzhuang oilfield of Raoyang depression were studied by core observation, granularity analysis and well log analysis. It can be seen that the aim stratum in the study area develop carbonate rock shoal, and the type of carbonate rock consist of algalsandclastic dolomite, oolitic dolomite , micritic dolomite , clasticbearing sand clasticoolitic dolomite. Carbonate shoal develop four microfacies: algal shoal , oolitic shoal, micritic carbonate bend and terrestrial grain shoal. The alternation of lake level, ancient landform, the strength of tectonic action and the provision of terrestrial material affect the carbonate shoal, and the change of micromilieu in the central uplift belt palaeogeomorphology directly affect the rock type and sedimentary microfacies, high terrain develop algal shoal and oolitic shoal, micritic carbonate bend appear in low terrain with low energy. Algal shoal and oolitic shoal is the best reservoir in the studied area, sedimentary microfacies analysis and facies model establishment can help Dawangzhuang oilfield's reservoir forecast, and can be a useful geologic model for reservoir forecast in other similar areas.
