印尼C油田为开发后期的老油田，如何进行三维地质模型的建立与运用是现阶段油田挖潜的关键。在层序地层学、沉积学、地质统计学等理论基础上，根据现有岩心、钻井、地震等资料，采用随机模拟方法，建立了精细的构造模型、地质约束下的微相模型和相控储层物性模型。通过地质建模，重新评估了油田采出程度，而沉积微相模型细化了沉积微相展布以及隔夹层分布，进一步明确了河道边缘类微相如决口扇、天然堤以及分布较稳定的隔夹层下部仍存在较高的剩余油潜力。三维地质模型的建立为后期剩余油研究打下了坚实基础。

It has been proven that C oilfield in Indonesia is at the late stage of development. How to build a subtle reasonable three-dimensional geological model is the major job at the present stage of remaining oil study. According to the core, wells and seismic data, the subtle structure model, geological constrained microfacies model and facies-constrained property model were established by using the stochastic simulation method at the theory of stratigraphy, sedimentary and geostatistics. By the geological model, the recovery degree was reappraised. Meanwhile, the distribution of the sedimentary microfacies and the interlayer were detailed by sedimentary microfacies to further indicate that potential of remaining oil existed at some microfacies like crevasse fan, levee and some sands under the regional interlayer. The establish of 3D geological model laid a foundation for the studying of the remaining oil distribution.
