摘要 河流相储层在大庆油田的产油层中占有重要比例,河流相储层的平面连续性是影响其晨均质的主要方面,是油藏精细描述和建模的基础和关键。近的来,众多得采用露头调查类比的方法进行油田地下储层的精细描述和建模工作,但受限于沉积环境,沉积条件的不确定性,该方法具有一定的局限性。 Fluvial reservoirs cover a fairly important proportion of production reserves.Areal continuity is a predominant factor that affects their heterogeneities,which also is essential for detailed reservoir description and modeling .In recent years,researchers made reservoir description and modelling by taking the techniques of outcrops investigation analogy.However,the application of outcrops analgy investigation is limited by the uncertainties of sedimentary environment and deposition condition.Based on the abundant static and dynamic state data,analysis of comprehensive utilization of sedimentary process ,sandbodies boundary,log curves and dynamic state were applied into subsurface study for detailed description of fluvial in area.Discussion is focused on subdividing of genetic unit,microfacies study, recognition of sandbodies of single channels and detailed description of their continuites.The achivements provide successful experiences for geological study of reservoir modeling and residual oil study of old oilfield during EOR.
