摘　　要：高精度储集层骨架模型是精细地质模型的重要基础。高分辨率层序地层学方法、储集层定量模拟技术以及密井网区精细储集层地质知识库的建立,是提高所建立砂体骨架模型精度的重要保证。通过使用变差函数,将地质、露头、三维地震、测井等静态和生产动态等各种信息有机地综合在一起,提高了井间砂体预测的精度,对于预测相似条件下稀井网地区的储集层分布也有理论指导意义。A fine geological model is presented based on a high-precision reservoir framework model, and the new technologies including high-resolution sequence stratigraphy, reservoir quantitative simulation technology and the foundation of fine reservoir geological database will be able to provide an important support for improving precision of framework model of sandstones. All kinds of data can be integrated by variation function. This method can apply all kinds of existing information, and improve precision of sandstone forecast between wells, and it will be meaningful for forecasting reservoir distribution in dilute well pattern zone with similar condition.
