陇东侏罗系油藏类型与开发特征

针对陇东侏罗系油藏的开发现状,详细分析了陇东侏罗系油藏的地质特征,根据油藏地质特征将侏罗系油藏分为厚层块状油藏、连片层状油藏、边底水油藏以及特低渗透油藏等类型;同时,详细分析了不同类型油藏的开发历史与动态资料,总结了不同类型油藏在开发过程所表现的特征,提出了不同类型油藏剩余油分布的有利区域,对更好地开发同类型油藏具有一定的指导意义。

Types and Development Characteristics of Jurassic Reservoirs in East-Gansu

to the exploitation condition of Jurassic reservoir in East-Gansu, geologic characteristics of the reservoir were analyzed. According to the geologic characteristics, the reservoir was divided into four kinds, including heavy bedded reservoir, bitty reservoir, marginal basal water reservoir and very low permeability reservoir. The history of exploitation and dynamical data of different reservoirs were also analyzed. By summing up the features of different reservoirs during exploitation, the profitable area of the distribution of remainin oil in different reservoirs was selected, which had instructional value to exuloit the same twe reservoirs.
