Roncador是在1996年发现的位于深海Campos盆地的一个大型油田。油田开发面积111km2,水深1500～1900m。Roncador有巨大的含油储量,包含不同类型的原油,油田内部表现出不同的地质特征。开发方案由4个含油气单元组成。第一个含油气单元即含油气单元1A,在正断层构造的上盘形成油气藏。含油气单元2、含油气单元3和含油气单元4在下盘形成油气藏。本文描述了油藏的主要发育特征,排水系统的模拟和设计,为克服油藏中主要的不确定因素所采取的措施,不确定因素包括流体类型、连通性和净含油层厚度。
Roncador was a large oil field discovered in 1996 in the deep-water Campos Basin. Oilfield development area of 111km2, depth of 1500 ~ 1900m. Roncador has huge oil reserves, contains different types of crude oil, the oil field shows different geological characteristics. Development program consists of four units containing oil and gas. The first oil and gas unit, ie, oil and gas unit 1A, forms a reservoir on the upper plate of the normal fault structure. The oil-bearing unit 2, the oil-containing unit 3 and the oil-containing unit 4 form a reservoir in the lower plate. This paper describes the main developmental characteristics of the reservoir, modeling and design of the drainage system, and measures to overcome major uncertainties in the reservoir. Uncertainties include fluid type, connectivity, and net oil-bearing thickness.
