Geological Modeling of the Terminal Fan Reservoir in Hai120 Block of Jilin Oilfield

Terminal fan system is distinguished in Hai120 block, which consists of three different microfacies proximal subfacies, middle subfacies and distal subfacies are identified by combining the core observation, log interpretation and electron microscopy viewing, each subfacies includes a number of microfacies. Reservoir characterization plays an essential role in quantitative reservoir description, it can improve capacity of understanding reservoir, thus in this paper we mainly detailedly characterise microfacies, which have prominent impacts on the reservoir properties, herein presents the connection between reservoir properties and the facies, plus applying stochastic modeling method to build reservoir properties model. This study has a direct role in guiding the oil field development.
