| Chad GreatBaobab oilfield is located in Bongor basin, west African rift system, where is affected by the china-africa shear zone in the development of new generation inland rift basin, overall a basket shape asymmetry fault depression. For the fan delta front sedimentary formation and development of a variety of microfacies type, purpose layer shallow, big span, reservoir physical property is better. In stratigraphic framework, sedimentary microfacies analysis, on the basis of the structural characteristics and reservoir characteristics of oilfield are analyzed, and the reservoir characteristics are studied. Through the study of the reserves producing status of reservoir classification analysis, to calculate the reserves of the results and evaluate the reserves. At the same time three geological model is established for history matching reserves. |
