【摘要】：乍得GreatBaobab油田位于Bongor盆地中、西非裂谷系交匯部位,是受中非剪切帶影響發(fā)育起來的中新生代內(nèi)陸裂谷盆地,整體為一不對稱箕狀斷陷。油層為扇三角洲前緣沉積,發(fā)育多種微相類型,目的層埋藏淺、跨度大,油藏物性較好。文在地層格架、沉積微相進行分析的基礎上,對油田的構(gòu)造特性和儲層特性進行了分析,并對油藏特性進行了研究。通過對油藏劃分進行儲量動用狀況分析,計算了儲量結(jié)果并對儲量進行評價。同時建立三位地質(zhì)模型對儲量進行歷史擬合。
[Abstract]:The GreatBaobab oil field in Chad is located in the middle of the Bongor basin and the junction of the West African rift system. It is a Meso-Cenozoic inland rift basin developed under the influence of the non-shear zone. The whole basin is an asymmetrical graben-like fault depression. The reservoir is a fan delta front deposit with many microfacies types. The target layer is shallow buried and has a large span. The reservoir has good physical properties. Based on the analysis of stratigraphic framework and sedimentary microfacies, the structural and reservoir characteristics of oil fields are analyzed, and the reservoir characteristics are studied. The reserve result is calculated and the reserve is evaluated by analyzing the reserve production condition of reservoir division. At the same time, a three-bit geological model is established to carry out historical fitting of reserves.
