【摘要】：作为我国中、新生代陆相盆地重要油气储集层系类型之一,辽河奈曼油田为加快油气勘探步伐,进一步搞好产能建设,需要进行精细油藏描述及剩余油分布研究。本文将地质、地震、测井、油藏工程、数值模拟等统一于油藏精细描述之中,结合新增的油藏静、动态资料,确定油层的划分标准,并对地层对比与划分到单层。对储层构造形态等进行研究,描述微构造剩余油富集的有利圈闭及微构造与剩余油的关系。分开发单元、主力小层进行微构造研究,建立分油层组、砂岩组的宏观构造模型和分开发单元的微构造模型。应用资料进行沉积微相研究,重点研究不同微相对开发的影响。开展储层的成岩作用、物性、非均质性、注水后变化特征研究;开展测井储层评价,建立储层地质模型。通过对流体的性质等在开发过程中的变化研究,建立油藏流体模型,分层编制不同流体平面分布图。最后,在沉积模型、构造模型、油藏流体模型及储层地质模型的基础上,建立九上段油藏三维综合地质模型,进行油藏地质综合评价。进行九上段油藏储量复算。剩余油分布富集规律研究。
[Abstract]:As one of the important types of oil and gas reservoirs in Mesozoic and Cenozoic continental basins, Liaohe Neiman Oilfield needs to study the fine reservoir description and the distribution of remaining oil in order to speed up oil and gas exploration and further improve productivity construction. In this paper, geological, seismic, logging, reservoir engineering and numerical simulation are unified in the fine description of the reservoir. Combined with the newly added static and dynamic data of the reservoir, the criteria for the division of the reservoir are determined, and the stratigraphic correlation and division to a single layer are made. The structure morphology of reservoir is studied to describe the favorable trap of microstructural residual oil enrichment and the relationship between microstructure and remaining oil. The microstructural model of the oil reservoir, sandstone formation and the sub-development unit is established by studying the microstructures of the main layers and the development units. The sedimentary microfacies were studied by using the data, and the effects of different microstructures on the development were studied. The reservoir diagenesis, physical property, heterogeneity, characteristics of changes after water injection are studied, well logging reservoir evaluation is carried out and reservoir geological model is established. Through the study of the change of fluid properties in the development process, the reservoir fluid model is established, and different fluid plane distribution maps are compiled by stratification. Finally, on the basis of sedimentary model, structural model, reservoir fluid model and reservoir geological model, a three dimensional comprehensive geological model of the upper segment of Jiujiu reservoir is established for comprehensive evaluation of reservoir geology. The reservoir reserves of the upper segment of Jiu are recalculated. Study on the Law of remaining Oil Distribution and enrichment.
