南堡凹陷柳赞油田扇三角洲储层地质建模

Geologic Modeling of Fan-Delta Reservoir of Liuzan Oilfield in Nanbao Sag

针对扇三角洲储层物性变化大、建模难度大的特点,以南堡凹陷柳赞油田扇三角洲储层为例,进行地质建模研究。应用岩石地层学、层序地层学、地质统计学等理论为指导,综合利用地震、钻井、测井和生产动态等地质资料,应用三维地质建模软件PETREL对工区进行构造建模、沉积相建模和储层物性建模,模拟出储层的三维空间分布,实现了储层地质特征的定量化和可视化,同时,对建立非均质性十分严重的扇三角洲储层地质模型进行方法和技术上的摸索,为同类油藏研究提供思路和方法的借鉴。

The fan - delta reservoir is characterized by the great variation of physical property and modeling difficulty. Studies on geology modeling is conducted by taking the fan - delta reservoir in Liuzan oilfield in Nanbao sag as an example. Based on lithostratigraphy, sequence stratigraphy and geostatistics, combining geologic data such as seismic, drilling, logging and production performance, structural modeling, precipitation facie modeling and reservoir physical property modeling of target area are established by using 3 - D geologic modeling software PETREL, and 3 - D distribution of the reservoir is simulated, which realize the quantification and visualization of the reservoir geologic characteristics.
