冀东南堡凹陷一号构造1-1区储层建模研究

Reservoir Modeling in the Block of 1-1 on No.1 Structural of Nanpu Depression in Eastem Hebei Oil Field

冀东油田南堡凹陷一号构造断层复杂、油水关系复杂、平面和层间差异大,油层评价难度大。受厚层玄武岩屏蔽影响,地震资料在低井控条件下不能满足储层分布研究需要。为此,需要建立一套低井控条件下的储层地质模型并形成相应的地质建模方法,为开发早期编制合理的开发方案提供可靠的依据。建模采用的是petrel建模软件,运用确定性建模与随机建模相结合的方法,即相控随机模拟法,建立了冀东油田南堡凹陷一号构造1-1区的三维地质模型。三维地质模型表征了储层的非均质性、揭示了油气的分布规律。

Owing to the complicated fault, the complicated relationship between oil and water, the deep gap between flat and level, the difficulty of reservoir evaluation in No. 1 structural of the Nanpu depression of eastern Hebei oil field, and because of the thick basalt, seismic data can not meet the research needs of reservoir distribution by the low well-controlled condition. So, a reservoir geological model with low well-controlled and forms the corresponding modeling method is need to establish, which provides geological foundation for the early development programs establishment. Petrel software is used in this block which combined deterministic modeling and stochastic modeling method,facies-controlled reservoir modeling,and established the 3D geological model in the block of 1-1 on No. 1 structural of Nanpu depression of eastern Hebei oil field. 3 D geological model have characterized reservoir heterogeneity and revealed oil and gas distribution.
